The acquittal of former Kosovo Prime Minister Ramush Haradinaj of war crimes, coupled with the recent acquittal of two Croatian generals, has revived suspicions in Serbia that the international court in The Hague is biased against them.

On the drive into Novi Sad you can pick up a ghost on the airwaves. Radio Krajina is a taste of their lost home for the Croatian Serbs who now live in Serbia's third-largest city.
There are requests, phone-ins and plenty of turbo-folk, the mash-up of traditional Balkan music and electronic beats that reached its peak popularity during the conflict of the 1990s.
It was the soundtrack to the end for the long-standing Serb community in Croatia's Krajina region. In August 1995, more than 200,000 people fled before, during and after Operation Storm - a massive military push by Croatian forces.
They came over the border in a ragged convoy of cars, lorries and tractors, carrying whatever possessions and livestock they could. Many ended up settling in Novi Sad and the surrounding region of Vojvodina.
Almost two decades later the refugees still come through the doors of the Humanitarian Centre for Integration and Toleration in the city centre. Some clutch plans and land titles for their former homes. A few dream of returning - most just hope to sell up so they can improve their lives in Serbia.
Dusan Starcevic is one of them. He says he walked for 11 days with his pregnant wife and infant son after their car broke down as they left Croatia in 1995.
Once a judge, he now practises law in Novi Sad - though his jacket and shirt suggest that either he does not care for expensive clothes, or he simply cannot afford them.
"Everything has gone," he says, holding back tears, before insisting that he no longer wants to talk about the past.
But he is keen to discuss recent events at the International Criminal Tribunal for the Former Yugoslavia (ICTY) in The Hague.
In particular, the decision of the appeal court to acquit two Croatian generals previously convicted of conspiring to drive Serbs out of Krajina.
"This verdict is very disappointing and inexplicable," says Mr Starcevic. "As a human being, I'm convinced that relations between people, states and groups are based on ethics and logic. This verdict is a severe attack on both of those."
But he admits the decision was not a complete surprise. Like many Serbs, Mr Starcevic is not convinced of the impartiality of the ICTY. The acquittal of the generals means that no Croatians have been convicted of crimes against Serbs during the conflict.
The 1995 offensive followed years of conflict between ethnic Serb nationalists and the newly-independent state of Croatia.
In 1990-1991 Serbs in Krajina declared their loyalty to the Serbian government led by Slobodan Milosevic and got help from elements in the Yugoslav federal army.
Croatia is set to join the European Union next year, and the cynical view here is that the Hague verdict ensures a clean slate. But it leaves Croatian Serbs who suffered during the conflict without justice - or much hope of it ever coming.
The founder of the Humanitarian Centre is another Croatian Serb - though Ratko Bubalo left a year before Operation Storm.
He offers smiles and a glass of home-made schnapps, before explaining the plight of the refugees. His organisation has dealt with 130,000 of them since 1995.   This does not just have local significance - it might shake Europe in the long term. "This does not just have local significance - it might shake Europe in the long term."
"They are a very vulnerable part of the population. Sixty-five percent of them don't have resolved housing and there are still some people in refugee centres."
Mr Bubalo is still trying to help the refugees recover their former properties - not just in Croatia but Kosovo and Bosnia as well. The proceeds of a sale could make a big difference to the lives of the displaced families.
But he says they are no longer expecting much in the way of satisfaction from the ICTY.
"Today it is difficult to talk about the tribunal. All hope for international justice faded away. This does not just have local significance - it might shake Europe in the long term."
Skourta Redjepi and her daughter Djila admit they no longer follow the tribunal at all. Members of a Roma family, they lived in Jablanica, where the Kosovo Liberation Army established a notorious base.
One day in 1998 a masked man came to the family's door and told them they had five minutes to leave. Djila says she hasn't seen her father since.
"We could never return to Kosovo - how could we?" she asks, rubbing her face. "We are afraid to go back. There is no justice."
In its latest decision, the tribunal cleared Kosovo's former prime minister Ramush Haradinaj of any involvement in atrocities at the Jablanica camp.
This prompted celebrations in Pristina - but anger in Belgrade. "Another slap in the face" was the pithy analysis of local media outlet B92.
The recent verdicts have left Serbs with little faith in the tribunal's ability to find justice for their suffering in the conflicts of the nineties.
Under the Milosevic administration, Serbian forces committed serious crimes in Bosnia, Croatia and Kosovo - and many of its former leaders have gone on trial in The Hague. But thousands of Serb civilians were also killed, and the ICTY has been rather less successful in holding to account those responsible.
As founder of Belgrade's Humanitarian Law Centre, Natasa Kandic campaigned to bring the perpetrators of the atrocities of the Balkans conflict to justice. She handed evidence to the ICTY which helped to convict the Serb perpetrators of the Srebrenica massacres in Bosnia.
But now she says the tribunal has failed to help victims come to terms with what happened - and that a new approach is needed for there to be any hope of reconciliation in the region.
"We need new thinking - we have to forget hostility and see all victims as equal. It is true that more Muslims, Croats and Albanians were killed than Serbs. But the Serbs who were killed also deserve justice."
It now seems unlikely that this will come through the ICTY. But Natasa Kandic believes that moving beyond a judicial process is the best answer to preventing future conflicts.
"We need a non-judicial body which will deal with victims, organise public testimony and show respect for all victims. That would change the current culture in our relations to victims. Today all societies in the region only have respect for their own victims."
"Without empathy for others, it is impossible to build a future, rule of law and reconciliation."


A rights watchdog has found the Republic of Ireland violated a European charter by not banning all corporal punishment, including smacking at home.

Corporal punishment was banned in Irish schools in 1982 and, by 1996, it was a criminal offence to hit schoolchildren.
However, the Republic of Ireland is one of the few European countries that does not ban physical punishment by parents.
The European Committee of Social Rights made its ruling after a formal complaint from a UK-based charity.
The Association for the Protection of All Children (Approach) lodged its complaint in February 2013 to the committee, which is part of the 47-nation Council of Europe.
The charity alleged that the Republic of Ireland has taken "no effective action" to remedy violation of Article 17 (the right of mothers and children to social and economic protection) of the European Social Charter by prohibiting all corporal punishment and other "cruel or degrading forms of punishment of children".
Approach said the existence, under Irish Common Law, of the defence of reasonable chastisement "allows parents and some other adults to assault children with impunity".
In its decision, published on Wednesday morning, the European Committee of Social Rights said none of the Irish legislation referred to it expressly banned "all forms of corporal punishment of children that is likely to affect their physical integrity, dignity, development or psychological well-being".
The committee concluded unanimously that Irish domestic law violates Article 17 of the European Social Charter.
The Irish Minister for Children James Reilly told the state broadcaster, RTÃ‰, that his department has started talks with the Department of Justice and Equality on removing the defence of reasonable chastisement from Irish law.
Mr Reilly said that in recent years, most parents have used other ways of disciplining their children.
However, he said he wanted to see the options available on abolishing the reasonable chastisement defence before considering any new legislation to ban parental smacking.
The minister added that he has instructed his officials to prepare regulations that would explicitly ban corporal punishment of children in foster homes or in the care of the state.
Corporal punishment was banned in Irish schools and some care settings under the Children Act of 2001, but it is still not explicitly banned in the home.
The United Nations and other organisations that protect children, including the Children's Rights Alliance, Barnardos and the Irish Society for the Prevention of Cruelty to Children (ISPCC) have been campaigning for some years to change the law on smacking.
The ISPCC said on its website that it believed "comprehensive, quality support and education of parents is essential in actively discouraging slapping and promoting positive, non-violent forms of discipline".
"A legal ban would serve the purpose of removing slapping as an option for parents and would steer and support parents to find alternative disciplinary methods," it said.
The European Social Charter is a legally-binding social and economic counterpart to the European Convention on Human Rights. The Republic of Ireland is a signatory to the charter.
The European Committee of Social Rights is made up of independent legal experts who assess whether countries are in compliance with their commitments under the charter.


A Hindu tailor has been hacked to death in a district of central Bangladesh, police say, the latest of a number of Islamist killings in the country.

Nikhil Joarder, who was in his early 50s, was attacked as he sat outside his shop in Tangail on Saturday afternoon.
Police said he had been arrested in 2012 for allegedly making derogatory comments about Islam, then released.
Islamic State claimed the attack although the authorities deny the group is active in the country.
A number of similar recent killings in Bangladesh have been claimed by various Islamist militant groups.
On Monday, Xulhaz Mannan, a leading gay rights activist and editor at the country's only LGBT magazine, was hacked to death along with another man in his Dhaka flat.
A Bangladeshi militant group affiliated to al-Qaeda, Ansar al-Islam, said it was behind those killings.
Last year, four prominent secular bloggers were also killed with machetes.
The four bloggers had all appeared on a list of 84 "atheist bloggers" drawn up by Islamist groups in 2013 and widely circulated.
The grim list of those who have fallen victim to attacks by Islamist militants in Bangladesh is growing ever diverse.
Secular bloggers, academics, gay rights activists, and members of religious minorities including Shia, Sufi and Ahmadi Muslims, Christians and Hindus have all been killed, many of them hacked to death.
That a university professor whose family said believed in God could also be murdered suggests the list of those at risk has widened further.
Who exactly is behind the attacks remains murky. Bangladesh has myriad extremist groups and there have been few convictions over the attacks.
Bangladesh has disputed claims by so-called Islamic State or al-Qaeda-linked groups for the attacks, instead often blaming opposition parties or local Islamist groups.
But until the killings stop the government itself will face accusations of not doing enough to protect minorities in the Sunni-dominated nation.


More than a quarter of people in Scotland do not take time to look after their mental health despite recognising its importance, according to a survey.

The Scottish Association for Mental Health (SAMH) is calling for people to talk to friends or family more about mental health issues.
A poll for the charity found most Scots believe their mental health is as, or more, important than physical health.
The online survey was filled in by more than 1,000 people in Scotland.
SAMH conducted the research earlier in the month to coincide with World Mental Health Day on 10 October.
The charity said figures showed that 86% thought their mental health and physical health were equally important, while 8% thought their mental health was more important than their physical health.
Jo Anderson, director of external affairs at SAMH, said: "We all have mental health, just as we all have physical health, and it's important that we look after it.
"This Mental Health Awareness Week we want to get people thinking about their own mental health and the kind of things that improve it.
"Throughout the week we'll be highlighting ideas and inspiration, and hope that people will get involved and share their own experiences."
The Scottish government said it had increased funding for psychiatric services since coming to power in 2007 and was committed to extending services.
MSP Clare Haughey, a registered mental health nurse and deputy convener of Holyrood's Health and Sport Committee, said: "Ensuring everyone is able to get effective mental health treatment is an important step in our efforts to create a healthier, happier society - and the increased funding to sit at nearly Â£1bn for psychiatric services is a positive development.
"The SNP is strongly committed to tackling mental health problems across Scotland - evidenced by this funding and the creation of a dedicated mental health minister in the Scottish government."


Derby Cathedral is to close midweek for more than four months as it undergoes its first refurbishment for 40 years.

The cathedral was given a grant of £500,000 to spend on heating and electrics and has raised another £170,000 for decorating.
Work will start in April with midweek services held in St Mary's Roman Catholic Church and the Chapel of St Mary on the Bridge until August.
The cathedral still needs to find almost £20,000 for the work.
The Dean of Derby, the Very Reverend Dr John Davies, said the decision to close the cathedral on Monday to Friday was a difficult one - but necessary.
"We really need to give the place over to the people who do the work otherwise it will go on for months and months and months," he said.
The paint that will be used in the decoration is specially-designed by Farrow and Ball and is described as "white with a hint of cream", called Derby stone.
The funding for the boiler came from the government's First World War Centenary Fund.


Prestatyn's former Ty Nant council offices will become a new medical centre for 23,000 patients, after being given the go-ahead by councillors.

The decision to lease the building to the local health board comes ahead of the closure of two GP practices.
Both practices will be merged into the new Healthy Prestatyn Iach centre, which health bosses said would create a "better and more responsive service".
The centre will open on 1 April, and will move to Ty Nant from December.
Healthy Prestatyn Iach will be run by the Betsi Cadwaladr University Health Board (BCUHB), and will have nine GPs, with one more due to be appointed alongside nurses, physios, occupational therapists, pharmacists, community workers, and midwives.
It will run alongside Healthy Rhuddlan Iach, where another GP practice is also due to close.
BCUHB central region's medical director Dr Chris Stockport said the decision was taken after the three existing GP practices experienced recruitment difficulties.
"Pendyffryn, the larger practice in Prestatyn, had lost three or four GPs over the past couple of years and those who remained were struggling with the workload.
"GPs at the other practices were finding it difficult to get time off as nobody could be found to cover for them."
The Ty Nant offices, which have been vacant since 2014, have attracted little interest since being put on the market.
Jamie Groves, Denbighshire council's head of assets and housing, said: "Reducing the budget through closing administrative buildings means we can protect valuable frontline services to the public."


A woman accused of murder injected herself with heroin after she allegedly stabbed, bound and gagged a pensioner in his home, the High Court has heard.

Margaret Henderson, 30, is accused of killing 67-year-old Eddie Girvan in his home in Greenisland, County Antrim.
The court heard claims that Mr Girvan pointed a sword at her during a row at the house on Station Road.
She was refused bail in the hearing. Defence lawyers said she denies the murder charge.
They added that her actions were in "self-defence".
Prosecutors said Mr Girvan's body was discovered tied up and seated inside his home on Station Road where he collected antiques and jewellery.
He had stab wounds to his chest and his shorts were round his ankles.
The court heard that officers had gone to the address to investigate a suspected burglary linked to a hit-and-run road collision at Donegall Quay in Belfast.
A Hyundai car belonging to the victim is believed to have been involved in the accident.
Henderson, a mother-of-two who was staying in a hostel on Verner Street in the city, had been arrested at that time on a separate bench warrant.
While she was being taken into custody police found keys for the Hyundai and a satellite navigation system registered to Mr Girvan's address, the court heard.
The vehicle was later recovered outside the hostel.
During police interviews Henderson allegedly admitted stabbing the pensioner, taking his car and also a gold chain she coerced others into pawning for her at a shop in Belfast.
Prosecution lawyers said Henderson claimed to have been with Mr Girvan when an argument led to him producing a sword and pointing it at her.
"She said she stabbed him with a knife used to cut cakes and then tied his hands and gagged him with kitchen roll to stop him shouting," the barrister said.
"She then stated that she injected herself with heroin at his house, stole his car and key, drove his vehicle which was involved in a collision on Donegall Quay and drove off back to her address where she was arrested."
As part of opposition to bail it was claimed that Henderson's drug addiction may lead to further offences.
A defence lawyer confirmed his client denies the murder charge.
"Based on the facts outlined this was certainly not a frenzied attack," he said.
"Ms Henderson describes being in fear, she describes being scared and she explains that her actions were in self-defence."
The court was told that the accused's continued addiction is linked to a family tragedy, but that she has been drug-free and achieved stability in her life since going into custody.
But denying bail, Mrs Justice Keegan cited the risks of re-offending and potential interference with the course of justice.

England's opponents in the tournament which runs from 8-20 August will be Italy, Netherlands and holders France.
The draw was made on Thursday at a ceremony staged at the City Hall in Belfast.
The matches will be played at Ballymena Showgrounds, Portadown's Shamrock Park, Mourneview Park in Lurgan and National Stadium at Windsor Park in Belfast.
Northern Ireland are playing in the final stages of the tournament for the first time.
The group winners and runners-up will face each other in the semi-finals at Windsor Park.
"Taking on Spain, who were finalists last year, in the first game will be a great occasion. They are a superb team from a top footballing country," said Northern Ireland coach Alfie Wylie.
"This is a fantastic opportunity for our girls to test themselves against the best teams in Europe."


Vulnerable eastern Europeans were trafficked to Plymouth and ordered to "urinate in bottles" and "eat outside", a court has heard.

Plymouth Crown Court was told the victims from the Czech Republic were brought to the UK and forced into compulsory labour.
The jury heard victims slept on a floor and in garages while the defendants pocketed their wages.
Five people deny trafficking and other charges.
The defendants are:
Judge Paul Darlow told the jury an earlier trial had to be stopped after concern about one of the interpreters.
Malcolm Galloway, prosecuting, told the court how the victims, some of whom worked as house servants, were sometimes threatened with violence or told their families at home were at risk.
The trial continues.


A man has been charged with manslaughter after the death of a 48-year-old in Gateshead.

David Swales died after a disturbance on Durham Road at about 23:00 BST on Wednesday.
Brian Elliott, 44, of Durham Road, who was originally arrested on suspicion of murder, has been charged with manslaughter.
He is due to appear at South Tyneside Magistrates' Court on Monday.
A 29-year-old woman who was arrested has been released without further action.


The economic impact of a week-long bike festival in the Borders has been estimated at more than £500,000.

The second edition of the TweedLove event was staged in the region in June this year.
National agency EventScotland has said that it generated significant additional spending in the area.
Festival director Neil Dalgleish said it was a "clear sign" of how important "cycling and bike culture" were to the Scottish Borders.
"I know that we can do even better if we continue to get support from our amazing bike community in the Borders together with businesses and government agencies," he added.
"Mountain biking and road cycling are more or less year-round activities in the Tweed Valley.
"We're very lucky to have such facilities on our doorstep and it's great to see what a contribution they can make."
He said it was important to keep developing trails and road routes throughout the area.
Tweedlove has also announced a sponsorship deal with Alpine Bikes for next year's event which will be extended to 10 days between 26 May and 5 June.


Boston Dynamics - the robotics firm owned by Google - has created a humanoid that is able to withstand all manner of bullying and still achieve its task.

Researchers push, kick and tease the remarkable new Atlas robot, which is an upgrade of models we've seen from the firm previously.
Despite the distractions, Atlas continues with its task of picking up and moving boxes.
In one instance, a member of the Boston Dynamics team gives Atlas such a severe whack to its upper back that it falls over, face first on to the floor.
After a moment of reflection, the robot pushes its arms out and jolts itself upright, before somewhat dejectedly walking out of the building.
Other demonstrations shown in the video posted by Boston Dynamics show Atlas walking around in the snow, righting itself whenever it encounters difficult terrain.
"It is electrically powered and hydraulically actuated," the company explained.
"It uses sensors in its body and legs to balance and LIDAR and stereo sensors in its head to avoid obstacles, assess the terrain and help with navigation."
The robot is 5ft 9in (175cm) tall and weighs 180lb (82kg).
We learned in December last year that plans to develop a four-legged dog-like robot had been shelved after it was deemed too noisy for its purpose on combat zones.
It had been hoped that the robot would be able to follow troops while carrying extra kit.

The sister of a Thai murder victim has criticised the police inquiry into the case and says she got death threats.

Hannah Witheridge, 23, from Norfolk and David Miller, 24, of Jersey, were killed on the island of Koh Tao.
Laura Witheridge said police "bungled" the investigation and had "nothing to tell us". She said she feels frightened after being sent defaced photographs from people in Thailand.
The Thai Embassy and Royal Thai Police have been asked to comment.
Burmese migrants Zaw Lin and Wai Phyo were last month convicted of the 2014 murders and sentenced to death.
Laura Witheridge made her comments in a public post on Facebook, which has since been shared more than 4,000 times, but has declined to speak to the BBC about the claims.
It comes after the family of Isle of Wight bricklayer Luke Miller, found dead in Kao Tao last week, said it had concerns over the inquiry into his death.
Miss Witheridge said her family had been expecting a briefing when they travelled to Thailand soon after Hannah's death to collect her body, but were instead "ambushed by a mob of hungry journalists" at police headquarters.
"The Thai police chief had no intentions of giving us an update… after all, the bungled investigation meant he had nothing to tell us," she said.
She claims she has had "many death threats from Thai people" since her sister's murder, has been sent crime scene photographs and been chased in her car.
"They defaced photographs of me saying that the killers had only done 'half the job'… people commented on these photographs saying things like 'there is still time', and 'tick tock tick tock'.
Miss Witheridge, who claims Thailand's "aesthetic beauty can lure you into a very dangerous trap", said she was now frightened of her own shadow and is constantly looking over her shoulder.
"I am exhausted, but frightened to sleep because of the nightmares. I miss my sister desperately," she said.
"My heart is heavy and my mind is tired."
Amnesty International has called for an independent inquiry over allegations Thai police tortured both defendants during the inquiry.
On their conviction in December Michael Miller, David's brother, urged those who had doubted the accused's guilt to respect the court's decision.


A fire at a children's playground in Staffordshire is being investigated by police.

The blaze happened in the village of Brown Edge early on Saturday.
People living in the area contacted police after noticing flames at about 01:30 BST. Residents said they were both angry and upset at the damage.
The Staffordshire force was chasing what it called "a number of lines of enquiry" and said it had suspects. No arrests have been made.


Vacuum cleaner manufacturer Dyson has lost its bid to change European energy labelling laws.

The company's founder, Sir James Dyson, argued vacuum cleaners were only tested when they were empty of dust.
He claimed that meant the tests misled "consumers on the real environmental impact of the machine they are buying".
In separate legal actions, the UK firm has claimed some rival vacuum cleaners are achieving misleadingly good ratings in tests.
The EU's General Court dismissed Dyson's action "in its entirety" because the company - best known for its bagless vacuum cleaner - had failed to show there were more reliable and accurate tests.
It said: "Dyson states that the regulation misleads consumers because the cleaning performance is tested only when the vacuum cleaner's receptacle is empty and not during use.
"The court acknowledges that the suction performance and energy efficiency of a vacuum cleaner with a dust-loaded receptacle will be reduced due to dust accumulation.
"It observes, however, that the [European] Commission could not use tests conducted on the basis of a dust-loaded receptacle, as they are not reliable, accurate and reproducible, as required by the regulation."
The court also dismissed Dyson's claim that current EU energy labelling laws "discriminates" in favour of bagged vacuum cleaners.
A Dyson spokeswoman said it was "deplorable" that the ECJ "endorses tests that don't attempt to represent in-home use, and we believe this is causing consumers to be misled."
The company added: "By this judgment, the ECJ has given its support to unrepresentative tests devised by the Commission with a small group of European manufacturers which in our view disregards the interests of consumers in Europe.
"The judgment is all the more surprising in view of the revelations about car testing in the VW scandal where the tests do not reflect real life usage.
"We don't believe the ECJ is acting in the interests of consumers and will continue to fight for testing and labelling, which is."
The ruling is a setback for Dyson, which last month began legal action against rivals Bosch and Siemens, alleging that they were misleading consumers in behaviour "akin to the Volkswagen scandal".
It claimed that independent testing had shown that machines made by Bosch and Siemens could draw more than 1600W of power when used in the home while containing dust, despite having a rating of 750W gained in dust-free testing.
That would mean that a rating as high as AAAA in test conditions could drop to an E or F in the home.
Last month, BSH Home Appliances, the parent company of Bosch and Siemens, said it planned to sue Dyson over the "unfounded and untrue" statements.
BSH chief executive Karsten Ottenberg said: "We have long since been aware that James Dyson has a history of taking a very aggressive approach against his competitors and has a desire to be in the public eye."
The company said all its vacuum cleaners were tested in accordance with the EU Energy Label and Ecodesign Directive for vacuum cleaners and met the standards in full.


A 40-year-old man has died after a crash with a fire service van near Crieff.

The man was driving a red Ford Fiesta which was involved in a collision with the van.
The incident happened on a stretch of the A85 Crieff to Perth Road, at the small village of Fowlis Wester, at about 18:20 on Saturday.
Three people who were in the van were taken to Ninewells Hospital in Dundee and treated for minor injuries.
The fire service van was returning to Perth from a routine call-out when the crash happened.
Any witnesses to the crash have been urged to contact police.


Doctor Who fans are getting a fresh opportunity to travel back in time with the discovery of two missing episodes from the long-running BBC series.

The 1965 and 1967 episodes star William Hartnell and Patrick Troughton, the first two actors to play The Doctor.
They are among more than 100 instalments which were not retained by the BBC.
The announcement was made on Sunday at Missing Believed Wiped, an event held at the British Film Institute (BFI).
The BFI, based in London, has been working with broadcasters and film collectors to recover missing recordings of many different television series.
Television programmes only began to be routinely recorded in the late 1950s. Previously, they were broadcast live.
Even when it became possible to make recordings, video tape was so expensive that most transmission tapes were wiped, so they could be re-used.
In the 1970s, the BBC commissioned a report by the historian Lord Briggs. His findings prompted efforts to improve the archiving of television programmes.
Although original transmission tapes did not survive, programmes were transferred on to film for broadcasters abroad and it is these prints that the BFI sometimes recover.
Doctor Who was sold all over the world in the 1960s.
The latest two episodes to be found were in the private collection of a retired broadcast engineer, Terry Burnett, who bought them at a school fete in Hampshire in the 1980s.
Mr Burnett had no idea the BBC did not have the recordings - it was only when he mentioned them casually in conversation to Ralph Montagu, head of heritage at Radio Times, that their significance was recognised.
Airlock is the third episode of a four-part story called Galaxy Four, transmitted in the autumn of 1965.
Hartnell is accompanied by Peter Purves, later a presenter on the children's series Blue Peter, and Maureen O'Brien, now better known as a novelist.
The plot involves the desperate attempts by the Drahvins, a race of cloned females, to escape a planet which is about to explode. The story also marks the only appearance in the series of tiny robots known as the Chumblies.
The other re-discovered episode is the second part of The Underwater Menace, from early 1967.
It sees a mad scientist attempting to restore Atlantis by draining the ocean into the Earth's core.
Patrick Troughton, in only his third appearance as The Doctor, was apparently unimpressed with the production.
In a recent biography, his son Michael says he argued with the director Julia Smith - who went on to become the original producer of EastEnders - complaining bitterly about the "ridiculous costumes and make-up of the fish people".
Innes Lloyd, who produced The Underwater Menace later admitted, "it did look like something from a '50s American 'B' movie".
The find makes only a modest dent in the number of missing episodes, with 106 instalments broadcast between 1964 and 1969 still being sought.
Among other items recovered and shown at Sunday's event were Emergency Ward 9, a play by Dennis Potter, and a comedy sketch featuring Peter Cook and Dudley Moore.


Campaigners are urging the government not to "cherry pick" different parts of the economy for special trade agreements with the EU after Brexit.

Three pro-EU MPs argue this approach risks creating "losers" because almost all sectors are linked to the EU.
Tory Anna Soubry, Labour's Chuka Umunna and Lib Dem Nick Clegg all want the UK to remain in the EU single market.
Pro-Brexit Tory Michael Gove says the single market is a "bureaucratic web" which the UK should leave.
The three pro-EU MPs are part of Open Britain, which replaced the official Remain campaign after the EU referendum.
At an event in London, they will present a report looking at different sectors of the UK economy and their links with the EU.
Written by the Centre for Economics and Business Research, it says every sector appeared to benefit from trade within the single market with 3.25 million UK jobs directly or indirectly linked to EU trade.
Manufacturing would "certainly suffer significantly" from restricted access to the single market, it says, while banking and insurance and professional services also have a "very strong link" to the EU and other sectors have "indirect" links.
"Although it might seem theoretically possible to cherry pick a number of sectors and negotiate trade agreements for the sectors, there is considerable linkage between the sectors," the report says.
"It has taken a quarter of a century to negotiate the single market as it exists today and could take nearly as long to renegotiate a new arrangement on a sectoral basis."
Any attempt to choose "winners" for free trade deals with the EU "cannot be achieved without the risk of creating 'losers' through reduced access and reduced future mutual benefits", it adds.
Ms Soubry will say: "There are no inevitable outcomes. There is no mandate for one particular Brexit option. The only question on the ballot paper was whether to leave, which we will, but how we execute our extraction must be debated."
The single market - which allows EU states to trade free of tariffs and other barriers - is central to the debate on what kind of deal the UK should seek when it leaves.
EU leaders have said access to, or membership of, the single market is dependent on the UK continuing to accept the principle of free movement, while Downing Street says people voted for greater control over the UK's borders and says it will not compromise on immigration controls.
Ministers have yet to set out in detail their negotiating aims, but say they want maximum possible access to the single market.
Prime Minister Theresa May has also said the UK will not seek to replicate other countries' trading arrangements with the EU, saying she will be pressing for a "bespoke" deal.
A spokesman for the Department for Exiting the EU said: "The government has been clear that we want to give British companies the maximum freedom to trade with and operate in the single market - and let European businesses do the same here.
"But we have also been clear that the UK should make its own decisions on controlling immigration and the authority of EU law should end.
"It's not in the UK's interest to give a running commentary on our thinking that could undermine our negotiating position."
On Sunday, ex-minister and Vote Leave campaign chief Mr Gove told the BBC's Andrew Marr Show: "I think when people voted to leave the European Union they voted to take back control of our money, our laws, trade deals and our borders.
"That means that the single market, that is basically a bureaucratic web, we need to be out of."
In other Brexit news, 81 MPs and peers have signed a letter to European Council President Donald Tusk calling for a deal to protect the rights of both Britons living in other EU countries and EU nationals in the UK.
The letter, co-ordinated by Conservative MP Michael Tomlinson, says people are not "bargaining chips" and calls for discussions to "move forward quickly".


Mae'r arweinydd Llafur, Jeremy Corbyn wedi ymweld ag etholaeth Gogledd Caerdydd ar ei ymweliad cyntaf â Chymru ers cyhoeddi'r etholiad cyffredinol buan.

Mae Llafur yn gobeithio ail-gipio'r sedd ymylol wedi iddyn nhw ei cholli i'r Ceidwadwyr yn 2010.
Wrth siarad am y tro cyntaf yng Nghymru dywedodd Mr Corbyn mai'r unig beth mae'r Ceidwadwyr yn cynnig yw "ofn a digalondid."
Roedd rhai cannoedd yn y dorf a dywedodd Mr Corbyn ei fod wedi "laru" ar y syniad bod Prydain heddiw yn wlad o "ddigartrefedd a banciau bwyd."
"Dw i'n eich annog chi i ddod gyda ni ar y daith yma o obaith a chynnwrf, ddim y siwrne o ofn a digalondid y mae'r Ceidwadwyr yn gynnig."
Roedd Prif Weinidog Cymru Carwyn Jones ymysg y rhai ddaeth i gyfarfod Mr Corbyn ar ei ymweliad a Chaerdydd.
Pan waeddodd aelod o'r gynulleidfa arno i "stopio Brexit", dywedodd Mr Corbyn mai Llafur oedd y blaid i gynnig gobaith a chyfleoedd i bawb.
Fe wnaeth ganmol Llywodraeth Lafur Cymru am ei pholisiau addysg a thlodi plant, gan feirniadu Llywodraeth y DU am gwtogi'r gyllideb i Gymru.
Ychwanegodd y byddai ei blaid yn sicrhau fod pensiynau'n cael eu diogelu ac na fyddai cwmnïau mawr yn cael closio at Adran Gyllid a Thollau ei Mawrhydi.
Dywedodd y byddai Llafur yn "rhoi diwedd ar Brydain glyd" lle roedd y breintiedig "yn rhoi swyddi i'w gilydd".
Roedd Llafur wedi dweud y byddai Mr Corbyn yn defnyddio'r ymweliad i drafod addysg, ar ôl iddo ddweud bod plant yn Lloegr yn cael eu gwasgu i mewn i ddosbarthiadau "enfawr" yn Lloegr.
Cafodd hynny ei feirniadu gan y Ceidwadwyr Cymreig, gan ddweud bod Llywodraeth Lafur Cymru wedi bod yn gyfrifol am gynyddu maint dosbarthiadau yng Nghymru.
Mae addysg wedi ei ddatganoli i Gymru.
'Crensian dannedd'
Mae arweinydd y Ceidwadwyr Cymreig, Andrew RT Davies yn honni y bydd tîm Llafur Cymru yn "crensian eu dannedd" yn ystod yr ymweliad.
Fe wnaeth y Ceidwadwyr ddal eu gafael ar Ogledd Caerdydd yn 2015 gyda mwyafrif o 2,137.
Dywedodd llefarydd Llafur ar Gymru, Christina Rees: "Y blaid Lafur yw'r unig ateb synhwyrol i'r Ceidwadwyr, a phleidleisio dros Lafur yw'r unig ffordd o gael gwared â Theresa May a'r Ceidwadwyr o lywodraeth."
Atebodd Mr RT Davies trwy ddweud: "Mae pleidlais dros Lafur yn bleidlais dros fwy o fenthyca, mwy o ddyled, Brexit anhrefnus ac amddiffyn gwannach."
Dywedodd Jonathan Edwards, AS Plaid Cymru dros Ddwyrain Caerfyrddin a Dinefwr: "O ystyried y gwendid ac anhrefn yn y blaid Lafur, mae'n ffantasi meddwl amdanynt fel llywodraeth Lafur y DU.
"Yng Nghymru fe fydd yr etholiad yma rhwng Plaid Cymru a'r Ceidwadwyr... Plaid Cymru sydd wastad wedi brwydro dros Gymru yn San Steffan ac fe fyddwn ni'n parhau i wneud hynny."
Dyw'r rhestr o gadfeysydd gwleidyddol Cymru ddim wedi newid llawer ar hyd y blynyddoedd, gyda rhestr bur faith o etholaethau lle'r oedd Llafur yn cwffio â'r Ceidwadwyr, a set o seddi lle roedd Plaid Cymru neu'r Democratiaid Rhyddfrydol yn herio.
Mae 2017 yn wahanol - os ydy'r polau yn weddol agos ati, ac os na fydd newid yn ystod y saith wythnos nesaf.
Mae'r seddi ymylol traddodiadol fel Gogledd Caerdydd, Bro Morgannwg ac Aberconwy yn ymddangos yn ddiogel yng ngholofn y Ceidwadwyr, tra bod rhai o fancyrs Llafur fel Delyn, Pen-y-bont a Gorllewin Casnewydd o dan fygythiad gan y don las.
Mae'r Ceidwadwyr wedi cipio'r tair sedd olaf yna o'r blaen ond roedd hynny yn ôl yn 1983 yn hirddydd haf Margaret Thatcher - annus mirabilis y Ceidwadwyr Cymreig pan etholwyd 14 o Dorïaid o Gymru.
Mae hyd yn oed yn bosib nad 14 yw'r uchafswm y tro hwn, wrth i lefydd fel De Clwyd a Wrecsam droi'n gystadleuol.
Ac nid y Torïaid yw'r unig bobl sy'n llygadu'r ceiri Llafur. Fe fydd Plaid Cymru yn cwrso yn Ynys Môn, sedd aeth i Lafur o drwch blewyn y tro diwethaf, tra bydd y Democratiaid Rhyddfrydol yn awchu am ddial yn eu cyn-gadarnle yng Nghanol Caerdydd.
Ar y cyfan mae'r etholiad yma'n cael ei gynnal ar yr adeg waethaf posib i Lafur, ond o leia' mae'n ymddangos bod y bygythiad gan UKIP yn yr ardaloedd ôl-ddiwydiannol yn pylu.
Ond, ac mae'n ond fawr, mae etholiadau'n bethau rhyfedd ac mae'r amseroedd gwleidyddol yn rhyfeddach fyth. Mae'n bosib y bydd y Ceidwadwyr yn cyrraedd y lan ac y bydd Mrs May yn ennill y fuddugoliaeth fawr y mae'n ei chwennych, ond peidiwch â betio'ch cot ar hynny.


More than 100 people have protested outside a site where unmanned aerial vehicles (UAVs) are tested.

Protesters from CND Cymru and other groups gathered at Parc Aberporth in Ceredigion and called for the end of military drone testing.
It was planned to coincide with a vigil at the Excel Arms Trade Fair taking place in London.
The Ministry of Defence (MoD) said the UAVs only flew at designated testing areas at Parc Aberporth.
"We're trying to raise awareness that Wales is part of the war machine," said John Cox, chairman of CND Cymru.
"Most people are unaware that Wales is part of the development of drones.
"They don't have bombs on board but they are testing out drones here."
QinetiQ, which works on UAVs, is one of a number of defence contractors working at Parc Aberporth.
An MoD spokesperson said: "Watchkeeper, an unarmed Remotely Piloted Air System (RPAS), only flies at the designated testing area at Parc Aberporth.
"Other UK RPAS aircraft, such as Reaper, only operate in Afghanistan under the legal authority of UN Security Council resolutions.
"These aircraft have played a vital role supporting military operations and have saved the lives of countless UK and allied forces by providing essential Intelligence, Surveillance and Reconnaissance."


An Australian firm has unveiled plans for a £70m mineral refinery on Teesside which would create up to 100 jobs.

Perth-based Peak Resources said a site on the Wilton complex, near Redcar, had been earmarked for the development.
The refinery would process minerals for use in a range of products including mobile phones, wind turbines and automotive parts.
The company said the devaluation of sterling since the EU referendum had made the project more cost-effective.
The Wilton site is already home to several major chemical companies.
If the proposals are approved by planners, production could start in 2019, the company said.
Managing director Darren Townsend said: "The choice of Tees Valley as the location for the refinery was compelling.
"Whilst the long-term impact of Brexit is not yet fully understood, the devaluation of the pound is expected to improve operating costs and the UK's progressive stance on maintaining competitive corporate fiscal regimes post Brexit are both positives."
Sue Jeffrey, leader of Redcar and Cleveland Council and Tees Valley Combined Authority member, said: "It is great that our area has been recognised as a preferred location by a company from the other side of the world, signalling a very clear indication of our global reputation for successful manufacturing."
Peak Resources currently mines and processes neodymium and praseodymium - two soft metals, found mainly in Tanzania.
Both are already used in the manufacture of components for electric cars and bikes, and wind turbines.


A 20-year-old man from Eritrea is nursing serious leg wounds after being shot twice by people he says were Eritrean soldiers stationed near the border with Ethiopia.

"Even after I fell down, I could hear the bullets whizzing past me," Weldab tells me from a clinic bed in Mai-Aini refugee camp in Ethiopia.
"I was lucky that I escaped. There were 10 of us in total; I don't know what happened to the rest of my friends."
This was the young man's second attempt to leave his homeland.
He walked for most of the journey. Many of the refugees I met walked, mostly at night to avoid being detected.
Some told me they paid traffickers between $100 and $700 (Â£65 and Â£450) to show them the way.
Others said that relatives in Europe have been known to pay the traffickers directly.
They would be taken by car part of the way and then shown the "safest" route by foot.
Although there is no war or famine in Eritrea, it accounts for the second largest number of asylum-seekers arriving in Europe, after Syria.
Weldab, who did not want to give his full name, had paid a fee to go to Europe the first time he tried to flee.
But it went wrong at the border with Sudan, when he was arrested on the Eritrean side and spent three weeks in police cells.
He told me that back home he only dreamt of two things: Playing football and going abroad - because he wants to avoid being conscripted into the army.
The UN has witnessed a huge rise in the number of people crossing from Eritrea into Ethiopia in May and June.
In just two days I saw nearly 500 refugees coming through dozens of illegal routes on the heavily guarded border.
Like Weldab, most are young people wanting to avoid conscription, which is compulsory after finishing school for both men and women.
It is supposed to last 18 months, but if not picked to continue their studies after this time - people can be forced to stay in the army until their 40s.
Many of the refugees are women, some carrying babies on their backs.

Eritrean migrants face new asylum battle
In one of the Ethiopian military camps that we visited, a section had been turned into a temporary shelter for those arriving.
Women and babies shared a few mattresses laid down on the floor of a structure made from wood and corrugated iron.
Outside in the scorching sun, more women sat in groups under the shades of trees.
Some young men covered their faces with their clothes and hands as we approached them, too afraid to be filmed.
"They won't talk to you," one elderly woman carrying a baby told me through an interpreter. "They are all scared."
Sitting next to the woman was a man in military camouflage, who said he had deserted the army after he was not allowed to leave despite being diagnosed with a serious ear problem.
"How could I continue serving under such pain?"
He left his wife and seven children behind and walked to the border with his gun; it took him just a day because he knew the area well.
"It is a tough choice as I don't know if I will ever see them again. But I know they will understand; it was a matter of life or death. At least here, they will know I am safe and alive."
He joins more than 150,000 Eritrean refugees living in Ethiopia and will get a new home in one of the six camps in the Tigray and Afar regions in the north of the country.
Young children have also been caught up in the exodus. In July alone, hundreds as young as seven made it to Ethiopia unaccompanied.
I met 13-year-old Yordhanos, who with her four friends now lives at special section of the camp reserved for children.
She too said she had left to avoid being conscripted when she left school.
"It was hard leaving our friends and families behind but we just ran because of fear," she says, explaining they literally ran over the border, terrified of being shot.
The area is heavily fortified because of a border war fought more than 15 years ago.
The children's compound has a football and basketball area and children are able to attend informal classes.
"I had an uncle here in Ethiopia, he came here nine years ago. But I don't know where he is," says Yordhanos, who hopes to make contact with him.
To try and discourage young people from carrying on to Europe, the UN refugee agency (UNHCR) and others have started projects like metal- and wood-workshops at the camps.
There are also computer and dress-making courses.
But UNHCR field officer Safi Ilunga tells me the migration continues.
"We try to show them how it is dangerous and risky to go."
Only three of the people I spoke to openly admitted they wanted to go to Europe, the rest were guarded about their plans.
But this is still Weldab's intention despite his injury - and despite the fact that the journey could end tragically in a desert or the Mediterranean Sea.
Europe is his goal, and he is determined to get there.


For amateur actors across the country, it is a dream come true.

The Royal Shakespeare Company has announced that 14 local theatre groups will join a company of professionals on a national tour of A Midsummer Night's Dream.
Over 12 weeks, 84 amateur actors will play the Mechanicals, the bungling labourers who put on a play for a wedding celebration.
The tour kicks off in Stratford-upon Avon, Warwickshire, in February 2016.
The RSC's Erica Whyman, who will direct A Midsummer Night's Dream: A Play for the Nation, said Shakespeare's comedy was "a very affectionate and fitting way to celebrate amateur actors everywhere".
In theatres across the UK, the local amateur company will share the stage with 18 professional actors, while Titania's fairy train will be played by local schoolchildren.
Like their Shakespearean counterparts, the amateurs playing "rude Mechanicals" - Quince, Bottom, Flute, Starveling, Snout and Snug - have a range of professions.
Becky Morris, from Ashfield in Nottinghamshire, is one of two women playing Bottom on the tour.
She will appear with the Lovelace Theatre Group at the Nottingham Theatre Royal in May 2016. "It's a gift of a part because the lines are so funny and there's a lot of physical theatre," she said.
"I've been in plays where the audience has numbered no more than 19. Capacity at the Theatre Royal is about 1,200, so I have no idea what that's going to be like."
Peter Cockerill, a pub landlord, will play Bottom at Newcastle's Northern Stage. He told the BBC he was "absolutely thrilled" to hear that he had won the part.
"It was a rigorous selection process with several auditions. I'm looking forward to working in a professional environment."
Mr Cockerill, who runs the Old Well Inn in Barnard Castle, County Durham, is a member of the Castle Players who are about to put on Shakespeare's The Merry Wives of Windsor.
"I'm learning lines for that," he said. "It's tempting to start learning the Bottom lines, but I don't think I should until I get this one out of the way."
The full list of amateur companies:
Whyman, the RSC's deputy artistic director, said: "We have cast people from all kinds of backgrounds, with a wonderful range of voices, shapes and sizes.
"But every single one of them has already demonstrated tremendous courage, skill and hard work to have survived the audition process and be selected to star in A Midsummer Night's Dream.
"And they have done all this whilst holding down a huge range of demanding jobs in the daytime. These first steps in creating a true 'Play for a Nation' have been inspiring, humbling and very refreshing."
A BBC One documentary series, The Best Bottoms in the Land, will follow the progress of the tour in spring 2016.
It is part of a series of programmes next year marking the 400th anniversary of Shakespeare's death.


Scotland has exceeded a target to reduce greenhouse gas emissions by 42% - six years early.

New statistics show its 2014 emission levels were 45.8% lower than in 1990.
The Scottish government had set a target to reduce emissions by at least 42% by 2020, and 80% by 2050.
Climate Change Secretary Roseanna Cunningham welcomed the "outstanding progress" and confirmed that the government would now set a "new and more testing 2020 target".
Figures published on the Scottish government's website also revealed that Scotland met its annual climate change targets for the first time since 2010.
But environmental campaigners said the loss of heavy industry and warm winters contributed more to the cut in emissions than bold government policy.
Ms Cunningham said a reduction in residential emissions in 2014 may have been due to something as simple as people turning down their heating.
"This underlines that small individual actions, if repeated on a large scale, can have a big impact in tackling climate change," she said.
The minister added: "This is an especially important time for climate change, in light of the international agreement reached in Paris last December and it is great news that Scotland continues to show ambition and demonstrates the progress that can be made.
"We will continue to rise to the challenge and the first minister has already confirmed that the Scottish government plans to establish a new and more testing 2020 target.
"We are not complacent and we will continue to take action and encourage others to do their bit to tackle climate change."
The government said the statistics showed that Scotland had outperformed the rest of the UK as a whole.
There was a 39.5% drop in Scottish source emissions between 1990 and 2014, compared to the UK's 33% reduction over the same period.
Jim Densham, of Stop Climate Chaos Scotland, said it was "great news" that Scotland had hit its target and it proved it was possible to cut emissions "while building a progressive and productive society".
"However apart from the electricity and waste sectors, it's hard to see a bold fingerprint of Scottish government policy driving the transition to a zero carbon economy," he said.
"This target has been met because of the loss of heavy industry, warmer winter weather, our changing share of European emissions credits and some government policies.
"Individual action is important but the Scottish government needs to lead with the big policies for major emission reductions."
The Scottish Greens' climate change spokesman Mark Ruskell said the figures show things are "moving in the right direction".
But he added: "Transport remains the Scottish government's weak spot, with road traffic back to where it was in 2007 and the hugely-polluting aviation sector doubling its impact.
"If we're to stretch our climate targets further, ministers are going to have to transform their policies and budgets, and the Scottish Greens stand ready to help them make those changes."
Claudia Beamish, of Scottish Labour, said it was "no time to be resting on laurels", despite the welcome news.
She urged the government to target a 56% reduction in emissions by 2020 and to aspire to generate 50% of "our heat and transport demand" from renewables by 2030.
In March this year, the UN climate change secretary praised Scotland's progress on climate change as "exemplary".
Christiana Figueres told BBC Scotland that she was impressed by the pace of change, and described the reduction in emissions since 1990 as "quite impressive".
The Scottish government will give a ministerial statement on greenhouse gas emissions at about 14:20, watch it live at Holyrood Live.


A Brighton arts centre is to be renamed in honour of Richard Attenborough when it reopens later this year.

The Gardner Arts Centre on the University of Sussex campus, closed since 2007, is undergoing a multi-million pound refurbishment.
It will be known as the Attenborough Centre for the Creative Arts (ACCA) when it reopens in September.
Lord Attenborough, who died last year, was the former chancellor of the university.
Early in his career, Lord Attenborough was hailed for his 1947 portrayal of teenage hoodlum and murderer Pinkie in Brighton Rock.
The university said the ACCA was also intended to be a memorial to his daughter Jane, a Sussex alumnus, who died in the tsunami on Boxing Day 2004.
Vice-Chancellor Professor Michael Farthing said the university was tremendously excited about the reopening of the grade II* listed arts centre.
"Our ambition is to see the ACCA become a dynamic cultural focus for the university campus and wider community, providing a home for the creative arts and creativity in its widest sense and serving as a catalyst for innovation and learning," he said.
The building, designed by Sir Basil Spence, was opened in November 1969 and originally named after local businessman Dr T Lyddon Gardner.


Broadcaster ITV has posted positive results for the start of the year, beating expectations.

The broadcaster, which airs popular drama Downton Abbey, said it had seen 14% growth in net revenue for the three months ending March 2015.
Total revenue was Â£665m, up from Â£585m during the same period last year.
Broadcast and online revenue was also up by 10%, to Â£530m, along with the studios division, which saw revenue increase by 17%.
Adam Crozier, ITV chief executive, said: "We've had a strong start to the year with further growth across all parts of the business.
"In April we completed the acquisition of Talpa Media, the creator of entertainment formats including The Voice, The Voice Kids, Utopia and Dating in the Dark, which marked an important step forward in our strategy of building a world-class production and distribution business."
ITV's results came out as staff staged a 24-hour strike to coincide with the company's annual meeting.  Unions have rejected a 2% pay rise, saying they should get a higher increase in view of the TV company's profits.
ITV's share price had dropped 1.5% by lunchtime.


Home Secretary Theresa May and former mayor of London Boris Johnson are set to enter the race to become the next Tory leader and prime minister.

They will declare their candidacies, setting out how much support they enjoy and how they propose to unify the party after the Brexit vote.
Ex-minister Liam Fox is also throwing his hat into the ring, joining Work and Pensions Secretary Stephen Crabb.
The outcome of the contest to succeed David Cameron is due on 9 September.
Mr Cameron, who has been Tory leader for 10 years and led the country since May 2010, is stepping down after losing the vote on the UK's future membership of the EU.
He has said fresh leadership is required to take on the task of negotiating the UK's separation from the EU.
The make-up of the field will become clear when nominations close on Thursday, although Mrs May, Mr Johnson and Dr Fox are expected to announce their intentions in a series of speeches in London.
Mrs May, who has been home secretary since 2010, told the Times newspaper that she was capable of "uniting Britain" and healing the divisions exposed by the Brexit result.
"Following last week's referendum, our country needs strong, proven leadership to steer us through this period of economic and political uncertainty, and to negotiate the best possible terms as we leave the European Union," she wrote.
The BBC understands Mrs May will announce a plan for a senior minister with a dedicated department to focus on the Brexit negotiations.
She has already won the support of cabinet colleague Justine Greening who told the Evening Standard that she had the "steeliness and professionalism" to secure the best outcome for the UK in Brexit negotiations and was also a "role model" for women coming into politics.
In the Times article, Mrs May calls for an ambitious programme of social reform to improve the life chances of those from disadvantaged backgrounds for whom job insecurity is the norm.
She also stresses her long experience in a top government role.
"Frankly, not everybody in Westminster understands what it's like to live like this," she writes. "And some need to be told that what the government does isn't a game, it's a serious business that has real consequences for people's lives.
She also wrote that the role of the state needed to be thought of differently.
"Instead of thinking of it always as the problem, we should acknowledge that often it is only the state that can provide solutions to the problems we face.
"So yes, the state needs to be small, but it needs to be strong."
In contrast to Mr Johnson, who was a leading supporter of the UK leaving the EU, Mrs May backed a Remain vote although she kept a low profile during the campaign and also indicated she would favour restrictions to freedom of movement rules if the UK stayed in.
Mr Johnson is expected to place Brexit at the heart of his "optimistic vision" for the country, saying the greater self-determination that leaving the EU will bring is an opportunity to "believe in ourselves and the values of our country".
The ex-London mayor has won the backing of figures on other sides of the EU referendum argument, including Environment Secretary Liz Truss who said his two victories in London showed his ability to "reach out" to people beyond the Conservative base.
She has said the Brexit vote meant "leadership must now come from someone who believes in, and campaigned for, leaving the EU".
Mr Johnson's campaign is being run by Justice Secretary Michael Gove, who was also a central figure in the Leave campaign. But an e-mail from Mr Gove's wife Sarah Vine to her husband, which emerged on Wednesday, suggested possible obstacles to a Johnson victory.
In it, she urged her husband to get "specific assurances" from Mr Johnson about what role he would have in a future government.
The e-mail, in which a member of the public is mistakenly believed to have been copied in, suggested party members, and press barons like Rupert Murdoch, would not have the "necessary reassurance" to back Mr Johnson without Mr Gove's input.
The two-month contest is inevitably being seen through the prism of the Brexit vote and who is best placed to negotiate an exit from the EU which protects the UK's economic interests while meeting the expectations of those who voted leave about controls on immigration.
Mr Fox, who finished third in the 2005 leadership election and was defence secretary between 2010 and 2012, said there could be "no backsliding" on referendum pledges on immigration, tweeting that "access to the single market does not require free movement".
He later told LBC Radio that "experience and background" were important characteristics in a future leader and that the leadership campaign could not be totally dominated by Europe - and that issues such as health and defence must feature too.


A prisoner was freed in error because he had the same surname as a convict due for release, it has emerged.

Anthony Douglas was released from HMP Hewell, near Redditch, on Wednesday instead of another offender who had completed his sentence.
Douglas, in his 20s and originally from Burton upon Trent, was arrested on Thursday after police were notified of the mistake. He is now back in jail.
The Prison Service said it had started an investigation.
"We take public protection extremely seriously and this type of incident is a very rare but regrettable occurrence," a spokesperson said.
The Ministry of Justice refused to confirm how long Douglas had left to serve on his sentence, or the details of his conviction.


China has said Japan is endangering peace in the region after it passed controversial laws expanding the role of its military abroad.

Japan should learn "profound lessons from history", China's defence ministry said after Japan's parliamentary vote.
The vote allows Japanese troops to fight overseas for the first time since the end of World War Two 70 years ago.
Tensions between China and Japan have escalated in recent months over a group of islands to which both lay claim.
The security laws were voted through Japan's upper house late on Friday, with 148 lawmakers voting in support and 90 against.
It followed nearly 200 hours of political wrangling, with scuffles breaking out at various points between the bills' supporters and opposition members attempting to delay the vote.

The government says that the changes in defence policy are vital to meet new military challenges such as those posed from a rising China.
But China's defence ministry said on Saturday they "run counter to the trend of the times that upholds peace, development and co-operation", the Xinhua news agency reports.
"The move has breached the restrictions of Japan's pacifist constitution," the ministry added.
Many Japanese who opposed the bills - which prompted large public protests - were also attached to the pacifist provisions in the constitution that banned fighting overseas.
China also urged Japan to "heed the security concern" of its Asian neighbours and do more to promote regional peace and stability.
South Korea, which also has a tense relationship with Japan, has warned Tokyo not to exercise the new defence laws without its approval.
But the US, Japan's ally, and the UK have both welcomed the changes.
UK Foreign Secretary Philip Hammond said he looked forward to Japan "taking an increasingly active part in peacekeeping operations".
Japan's post-World War Two constitution bars it from using force to resolve international conflicts except in cases of self-defence.
The new security legislation allows Japan's military to mobilise overseas when these three conditions are met:
What's behind Japan's military shift?
Critics say the changes violate the pacifist constitution and could lead Japan into US-led wars abroad.
Supporters of the measures insist they are essential for the defence of Japan and its regional allies, and will permit greater involvement in peacekeeping activities around the world.
Critics have focused on what they say is ambiguity in how the principles of the legislation will be interpreted, and the possibility that future governments will interpret them more broadly.


A Tintin comic strip by Belgian cartoonist Herge has fetched a record 1.6m euros (£1.1m) at auction in Paris.

The double-page strip from Tintin, King Ottokar's Sceptre was published in Le Petit Vingtieme in 1939.
The dramatic clear-line drawing contains an impression of Tintin and his dog Snowy aboard a crashing plane.
The artwork, which sold at auction house Sotheby's, had a guide price of up to 800,000 euros (£575,000), but sold for almost double the estimate.
It was sold following a bidding war between four potential buyers, the auction house said.
'Admirable catalogue'
The auction saw 65 original items by some of the biggest names in European and American cartoons go under the hammer.
The collection had belonged to Jean-Arnold Schoofs, one of the world's leading strip cartoon collectors.
Following the sale, Mr Schoofs said he was "very happy with the results, which were worthy of an admirable catalogue and did justice to all the authors - not only the most famous in the field, but also several somewhat forgotten by history".
"I am particularly happy with the results obtained by some pages by Herge and Graton that are very rarely seen in the market," he added.
A total of 2.7m euros (£1.9m) was raised, with five lots breaking world records.


Four days of Diamond Jubilee events have culminated in an appearance by the Queen on the Buckingham Palace balcony in front of huge crowds.

There was also a flypast by World War II aircraft and the Red Arrows.
The Queen had earlier attended a service at St Paul's Cathedral where the Archbishop of Canterbury praised her "lifelong dedication".
But her consort, Prince Philip, has been absent from her side as he remains in hospital with a bladder infection.
The Earl and Countess of Wessex
          visited the Duke of Edinburgh on Tuesday afternoon
.
Afterwards, Prince Edward said: "He's feeling better." The countess added: "He's in good spirits; he's on good form."
The Queen has recorded a two-minute message of thanks to the nation which will be broadcast at 1800 BST on radio and television in the UK and across the Commonwealth.
Crowds built up from early morning outside St Paul's and Buckingham Palace.
There was a fanfare as Her Majesty, wearing a mint green outfit of fine silk tulle, embroidered with tiny star-shaped flowers, arrived at St Paul's for the service at 10:30 BST and the crowds chanted "God save the Queen".
Prime Minister David Cameron, who gave a reading, led the large representation from the government, military personnel and members of the royal household, at St Paul's alongside diplomats and foreign leaders.
Following the service at St Paul's, the Queen attended a reception at nearby Mansion House - the official residence of the Lord Mayor of London.
The Prince of Wales and Duchess of Cornwall, the Duke and Duchess of Cambridge and Prince Harry were at a similar event at the Guildhall.
All of the senior royals then moved on through crowd-lined streets to a lunch at Westminster Hall where they dined on salmon, followed by Welsh lamb, grilled Isle of Wight asparagus, Jersey Royal potatoes and chocolate delice, bread and butter pudding and berry compote with apple sauce.
The Queen travelled in an open-topped coach with the Prince of Wales and the Duchess of Cornwall back to Buckingham Palace.
Princes William and Harry and the Duchess of Cambridge followed in a second coach.
They were led along The Mall by soldiers from the Household Cavalry Mounted Regiment, and the King's Troop, Royal Horse Artillery, then fired a 60-gun salute.
The day culminated with an appearance by the Queen and other senior royals on the balcony for the flypast, which had been in doubt due to the threat of bad weather.
The BBC's Gerry Holt, on The Mall, said the deafening sound of the flypast drowned out the crowd's cheers. She said that after the Red Arrows had passed overhead there were cries from youngsters of "The sky's turned red, white and blue!"
BBC royal correspondent Peter Hunt
 said the choice to have only six members of the Royal Family - the Queen, Prince Charles, the Duchess of Cornwall, Princes William and Harry and the Duchess of Cambridge - sent a message demonstrating both continuity and restraint at a time of austerity.
Among other Jubilee news:
Other highlights of the Jubilee weekend included a star-studded concert outside Buckingham Palace on Monday night.
At the show, Prince Charles paid tribute to his mother, describing her as "mummy" and a "very special person" but said there was  disappointing edge to the night because his father could not be there.
Afterwards the Queen came on to the stage to press a diamond-shaped crystal into a pod, igniting a beacon in The Mall to mark her 60 years on the throne. It was one of more than 4,000 lit across the UK and the Commonwealth.

A Fife businessman is facing a jail sentence after being convicted of abusing a primary school girl.

Shamas Ali, 47, forced the youngster to massage him and touch his legs before carrying out sex acts.
Ali had denied the indecency offence committed at houses in Dunfermline but was found guilty by a majority verdict at the High Court in Edinburgh.
He was found guilty of abusing the girl when she was aged between seven and 11, up to August 2003.
The victim, now aged 22, gave evidence against Ali, who is from Dunfermline.
Defence solicitor advocate John Scott QC asked that Ali's bail be continued after the verdict.
He said Ali had no criminal record of any significance and no breaches of bail.
Mr Scott said: "Whilst a custodial sentence is all but inevitable, there is no reason to think he would fail to comply with bail conditions."
The judge told Ali: "You have been convicted of a serious sexual offence."
Lady Wise said she was prepared to continue his bail while a background report was prepared ahead of sentencing next month.
But she told Ali: "You should not be under any illusion that says anything about the ultimate disposal."
Ali was placed on the sex offenders' register.


Charges have been dropped against two Blackpool fans accused of harassing the football club's chairman Karl Oyston.

Stephen Reed, 58, and David Ragozzino, 33, were charged after an investigation into text messages sent to Mr Oyston.
Mr Reed, of Common Edge Road and Mr Ragozzino, of Oakwood Close, both Blackpool, appeared before city magistrates earlier.
The court heard the Crown Prosecution Service has discontinued the case after a review of the evidence.
A CPS spokeswoman said: "After receiving further information from the police we have conducted a review of all the evidence in the case and have concluded that there is no longer a realistic prospect of conviction against either defendant for a charge of harassment and have therefore taken the decision to discontinue the case."


The next ice age may have been delayed by over 50,000 years because of the greenhouse gases put in the atmosphere by humans, scientists in Germany say.

They analysed the trigger conditions for a glaciation, like the one that gripped Earth over 12,000 years ago.
The shape of the planet's orbit around the Sun would be conducive now, they find, but the amount of carbon dioxide currently in the air is far too high.
Earth is set for a prolonged warm phase, they tell the journal Nature.
"In theory, the next ice age could be even further into the future, but there is no real practical importance in discussing whether it starts in 50,000 or 100,000 years from now," Andrey Ganopolski from the Potsdam Institute for Climate Impact Research said.
"The important thing is that it is an illustration that we have a geological power now. We can change the natural sequence of events for tens of thousands of years," he told BBC News.
Earth has been through a cycle of ice ages and warm periods over the past 2.5 million years, referred to as the Quaternary Period.
This has seen ice sheets come and go. At its maximum extent, the last glaciation witnessed a big freeze spread over much of North America, northern Europe, Russia and Asia.
In the south, a vast expanse of what are now Chile and Argentina were also iced up.
A fundamental parameter determining what dips Earth into an ice age is the changing nature of its orbit around the Sun.
The passage around the star is not a perfect circle and over time our planet's axis of rotation also rocks back and forth.
These movements alter the amount of solar radiation falling on the Earth's surface, and if a critical threshold is reached in mid latitudes in the Northern Hemisphere then a glaciation can be initiated.
Dr Ganopolski colleagues confirm this in their modelling but show also the role played by the concentration of greenhouse gases in the atmosphere.
And one of their findings is that Earth probably missed the inception by only a narrow margin a few hundred years ago, just before the industrial revolution took hold.
"We are now in a period when our (northern) summer is furthest from the Sun," the Potsdam researcher explained.
"Under normal circumstances, the interglacial would be terminated, and a new ice age would start.  So, in principle, we are in the perfect conditions from an astronomical point of view. If we had a CO2 concentration of 240 parts per million (200 years ago) then an ice age could start, but luckily we had a concentration that was higher, 280ppm." Today, industrial society has taken that concentration to over 400ppm.
The team says that an interglacial climate would probably have been sustained anyway for at least 20,000 years, and, very probably, for 50,000 years, even if CO2 had stayed at its eighteenth century level.
But the almost 500 gigatonnes of carbon that has been released since the Industrial Revolution means we will likely miss the next best astronomical entry point into a glaciation, and with a further 500 gigatonnes of emissions the "probability of glacial inception during the next 100,000 years is notably reduced", the scientists say in their Nature paper.
Add a further 500 Gt C on top of that and the next ice age is virtually guaranteed to be delayed beyond the next 100,000 years.
Commenting on the study, Prof Eric Wolff from the University of Cambridge, UK, said: "There have been previous papers suggesting that the next ice age is many tens of thousands of years away, and that the combination of seasonal solar energy at the latitude where an ice sheet would form, plus CO2, is what determines the onset of an ice age.  But this paper goes much further towards quantifying where the limits are.
"It represents a nice confirmation that there is a relatively simple way of estimating the combination of insolation and CO2 to start an ice age," he told the Science Media Centre.
And Prof Chris Rapley, from University College London, added: "This is an interesting result that provides further evidence that we have entered a new geological [Epoch] - 'The Anthropocene' - in which human actions are affecting the very metabolism of the planet."

GoPro has announced a new camera that is smaller and lighter than its earlier models.

The US firm already dominates the action-cam market, having sold more than $363m (Â£233m) worth of goods over the first three months of the year.
The Hero4 Session benefits from being waterproof without needing a special case, but cannot go as deep as models fitted with separate housings.
One expert said the firm risked having a "confusing" choice of products.
GoPro is marketing the new camera as being 50% smaller and 40% lighter than other Hero4 models.
It is:
Although the new camcorder may appear to have lower specifications than the firm's other options, GoPro suggests that its compact form coupled with a new dual-microphone system - designed to better handle wind noise - should appeal to customers intending to use it on a regular basis.
"We challenged ourselves to produce the smallest, lightest, most convenient GoPro possible," said the firm's founder Nicholas Woodman.
"Sound quality is as important as image quality and we're very excited about the stunning audio advancements we've made."
Costing Â£330, the Hero4 Session is only outpriced by the company's top-end Hero4 Black.
One tech industry watcher said it would probably have "niche" appeal, but added that GoPro's current line-up risked bewildering consumers.
"GoPro owns so much of the market that this is about trying to scoop up whatever is left," said James Trew, deputy managing editor of the Engadget news site.
"It used to have just three cameras - good, better and best - and you paid for the one you thought was your level.
"Now, in an effort to grow, I think there is a risk that it will start confusing customers, especially when the price of the Session is very similar to what are, on paper, better products.
"But there will be some people it will call out to - for instance, people who might think this looks better on their helmet."
GoPro faces a growing number of rivals, with EE, Xiaomi, Garmin and HTC among companies to have launched their own action cameras over recent months.
The California-based firm notes, however, that it currently accounts for all of the US's top five best-selling products in the digital camera/camcorder category, according to data published by market research firm NPD.
Even so, Mr Trew suggested that executives might feel they need to prove they are not complacent.
"GoPro went public last year so they have a whole new set of pressures to deal with," he explained.
"I think that's part of why we're now seeing more different stuff - including 360-degree camera mounts, virtual reality systems and broadcast technologies - to illustrate that it is staying ahead of the game in the face of increased competition."


Scientists says the condition of Australia's Great Barrier reef  is getting worse and some of the corals are degrading.

It's one of the seven natural wonders of the world and the only living thing on earth visible from space.
Scientists says an Australian government plan to protect the Reef in the future won't work.
They say it doesn't look at the damage caused by climate change, poor water quality and fishing.
Professor Terry Hughes, from the Australian Academy of Science, says it also doesn't take into account expansion of coal ports along the Queensland coast.
They want much better action to maintain the reef as it is now and also protect it in the future.
The public have been putting forward ideas  on how to protect and manage the  reef  from 2015 to 2050.
A plan drawn up as a result, will be studied by the World Heritage Centre in January.
Today, the Australian Environment Minister Greg Hunt said : "We have a clear plan and a strong commitment to ensure the reef is healthy and resilient.''
"Water quality in the World Heritage area is improving as farmers and governments stop using fertilisers, chemicals and reduce sediments running off farming land into the rivers and creeks along the Queensland coast."


The number of older people affected by chronic conditions and disability is set to soar in the next eight years, experts have warned.

Latest research suggests that by 2025 there could be nearly three million people over the age of 65 needing care in England and Wales - a 25% increase since 2015.
The Health Foundation last year estimated pressures on social care in Wales would rise by about 4.1% a year over the next 15 years due to population changes, the nature of complex and chronic conditions and rising costs.
It is a challenge that all levels of government have to grasp.
Social care covers everything from help in an individual's home for tasks such as washing and dressing, to round-the-clock help in a care home or nursing home.
The way the system works is different, depending on which part of the UK a person lives in.
But unlike the NHS, social care is not usually free.
Some people aged 65 and over will get help towards their costs, but others can pay the full cost.
Social care for the elderly takes up around a third of Welsh councils' social services budget - more than £550m in 2016-17.
IF SOCIAL CARE IS DEVOLVED, DOES UK POLICY STILL MATTER?
The devolved governments in Wales, Scotland and Northern Ireland each set their own rules.
But that is not to say that decisions made on social care in England would have no bearing at all on policy in Wales for example.
If the UK government decided that the state should contribute less and that a higher proportion of the social care budget in England should be paid for by the personal savings and incomes of individuals receiving care and their families.
Then that could mean less money being allocated to Wales from Westminster through the Barnett funding formula.
SO WHAT IS THE SITUATION IN WALES?
1: Care in own home
The maximum someone has to pay in Wales for care in their own home is capped in Wales at £70 per week.
Those with savings of less than £24,000 (not including the value of their own home) - could pay less.
But it is up to councils to determine whether a person's needs are severe enough to make them eligible for help - and most set the bar at the two highest levels - "substantial" or "critical".
However, from April 2016, everyone has a right to have their needs assessed.
The Welsh Government says 20,000 people in Wales benefit by paying this maximum or less for care in the home.
Councils get £13m to operate this cap.
2: Care homes
People with assets of more than £30,000 (including the value of their home if it is unoccupied) pay the full cost of their residential care but if your resources fall below £30,000, you then qualify for financial help.
The amount an individual then has to pay is determined on the basis of their income (e.g. from pensions or benefits).
The Welsh Government has pledged to increase the limit to £50,000 by the end of this assembly term in 2021. They say that could benefit about a quarter of the 4,000 or so people who currently pay the full cost of their care.
People who need nursing care (because of a health need) can get a contribution from the NHS towards their costs - and some could even get all their fees met.

WHAT ABOUT ENGLAND?
As things stand, those with individual assets of more than £23,250 have to pay for the full cost of that care regardless of whether it is in a care home, nursing home or in their own home.
The value of a home (as in Wales) is only included if a patient receives care at a care or nursing home.
But from April 2020 - the UK government had delayed the original 2016 date - the cost of care was set to be capped at £72,000 from the age of 65 onwards.
However, that sum only included the care element. Some £230 a week of the costs charged by the care home will not count, as these are being classed as living costs that people would have to pay in the community to cover things such as accommodation, food and bills.
As in Wales, people needing nursing care get a contribution from the NHS towards their costs.
The Conservatives in their manifesto proposed a further revamp.
Under the plans nobody who has assets of less than £100,000 would have to pay for care.
But crucially that calculation included the value of the house - for people paying for care in their own homes.
If their assets are above £100,000 they will have to pay until their value reaches that cut-off point.
The party said nobody would have to sell their house in their lifetime, or that of a surviving partner, but ultimately care costs would be taken from their estate.
But following criticism the prime minister announced there would be an "absolute limit" on the money an individual would have to pay - although the manifesto mentioned no such cap.
SCOTLAND
In Scotland, anyone over 65 is entitled to free personal care if they are assessed as needing help.
It is up to local authorities to set their criteria for who is eligible. Most have set it at substantial or critical level.
Personal care includes support to wash, dress and prepare meals. It does not, however, cover the cost of supplying the meals or for tasks such as help with shopping.
Anyone who needs care which requires a qualified nurse have that provided free by the NHS.
If an individual is in a care or nursing home they will get £171 towards personal care and £78 towards their nursing care if they have a medical need.
However, they may be entitled to some help if their assets - and that could include their house - fall below £26,250 (it will rise to 26,500 in June 2017).
They will be assessed to see how much they can contribute.
Everyone is entitled to keep at least £16,250 (rising to £16,500 in June 2017).
NORTHERN IRELAND
Social care is much more integrated in Northern Ireland. There are five health and social care trusts, which assess the help people need.
For people over the age of 75 most care in the home is provided free.
Those who are under the age of 75 may have to pay towards their care. Any charges are at the discretion of the local trust.
If someone needs to be looked after in a care home or nursing home, those with assets of over £23,250 - and that may include the value of the individual's property - pay for the full cost of their care.
Those with less may be entitled to some help - and everyone gets to keep at least £14,250 of assets.


Renaming Cardiff Airport in memory of Princess Diana would boost international recognition, a former councillor has said.

Mohammed Sarul Islam believes changing the name would generate publicity and act as a memorial.
The former Cardiff councillor has put forward a petition calling on the Welsh Government to change the name.
Assembly members will consider the petition, which gathered 16 signatures, on Tuesday
A petition needs a minimum of 10 signatures to be discussed by the Assembly Petitions Committee, under current assembly rules.
Mr Sarul Islam, president of the Commonwealth Business and Investment Council for Wales, said rebranding the airport with such a well-known name would attract international customers.
It is not the first time calls have been made to rename the airport, bought by the Welsh Government for Â£52m in 2013.
Previous suggestions include rebranding it the Robert Owen International Airport of Wales - after the Welsh pioneer of the Cooperative Movement - and Dylan Thomas International Airport Cardiff.


Investors in a financing scheme aimed at helping the UK film industry are being asked to repay "multiple millions of pounds" following a court ruling.

HMRC is pursuing investors in the Eclipse scheme, including celebrities, financiers and sports stars, for up to 20 times their original investment.
Courts ruled that the film investment partnership was in reality a tax avoidance scheme.
But an adviser to many of the investors said some of them now faced bankruptcy.
Nick Wood, a partner at Newport Tax Management, said: "There are a large number of people who have been left completely distraught.
"They have been given a three-month window to come up with what in some cases will be multiple millions of pounds."
The Eclipse partnership lost a Supreme Court appeal earlier this year over its use of tax breaks introduced by the government in 1997 to encourage investment in the film industry.
Now HMRC is demanding that investors repay their original investment many times over, because of the way the scheme was designed.
BBC business correspondent Joe Lynam said that to make a £1m investment, an Eclipse partner might contribute only £20,000 of their own money and borrow the rest.
"The tax relief on the whole amount would have been up to £400,000, or 20 times what they had risked. Here, HMRC may seek to recover the full £400,000," he said.
Labour MP Margaret Hodge, who chairs the all-party group on responsible taxation, said HMRC was right to pursue investors.
"If somebody cheats the benefit system, they have to pay the money back and are named and shamed. If somebody cheats the tax system, they should be treated in exactly the same way," she said.


Middlesbrough have signed Watford's Algeria midfielder Adlene Guedioura on a two-and-a-half-year contract for an undisclosed fee.

Guedioura, 31, has made over 170 appearances since arriving in England in 2010 for Wolves, Nottingham Forest and Crystal Palace, as well as Watford.
He was linked with a move to Boro's Premier League rivals Hull City.
Guedioura is the club's fourth January signing after forwards Rudy Gestede, Mikael Soisalo and Patrick Bamford.
Gestede, 28, joined from Aston Villa, Soisalo, 18, made the switch from Finland's Ilves Tampere while Bamford, 23, has moved from Premier League leaders Chelsea.
Middlesbrough are 15th in the Premier League table, two points above the relegation zone.

Police are investigating whether a street stabbing in Renfrewshire at the weekend was football-related.

A 40-year-old man was attacked in Westburn Avenue, Paisley, at about 14:55 on Sunday - shortly after the Rangers v Celtic game at Hampden ended.
The victim is in a stable condition at a hospital in Glasgow.
Police are following a positive line of inquiry. It is understood the incident is being treated as attempted murder and possibly football-related.
The injured man was taken by ambulance to Paisley's Royal Alexandra Hospital after the attack and later transferred to the Queen Elizabeth University Hospital in Glasgow.


It is almost 19 years since Davide Gualtieri scored the goal that still has people asking him for his autograph - and left Graham Taylor wondering whether his time as England manager really was cursed.

Just 8.3 seconds after San Marino kicked off their World Cup qualifier with England on 17 November 1993, Stuart Pearce's under-hit backpass allowed Gualtieri to nip in and prod the minnows into the most unlikely of leads.
"I will never forget that moment," Gualtieri told BBC Sport. "I had dreamt about it but I never thought it would happen. It was so hard for us to score against anybody, let alone a team as big as England."
"The stage is set for England's last and decisive match in this World Cup qualifying group. England in red, San Marino in blue, England needing to win by a seven-goal margin and hope that Poland can do them a favour in Poznan against Holland. [Whistle sounds to start game.] I'm sure you're aware now what's at stake. And Nicola Bacciocchi the number nine picks the ball up straight away and San Marino launch the first attack, oh and a mistake by Stuart Pearce and San Marino have scored. I don't believe this."
When I spoke to him this week, Taylor could not remember the name of the player who inflicted on him the final ignominy of his time as national manager, but he did not need reminding that the goal remains the fastest scored in a World Cup match - qualifiers or finals.
With  for the first meeting between the two nations since, I felt slightly guilty asking Taylor to relive some of the agony it involved - although it clearly hurt him a lot more at the time.
Taylor told me: "When the ball went into the net, I looked up towards the sky and just said quietly to myself 'god, please tell me what I have done wrong'.
"I can laugh about it now because that is a true story. Normally I would accept responsibility for every result, and every goal but, I mean, we were eight seconds into the game. I knew we would go on and win but you think to yourself 'what the hell is happening here?'
"His name hasn't stuck in my memory but I can picture the goal as I'm talking to you now. I can see Stuart and David Seaman and the San Marino player slipping in and putting it into the net. I can see it happening, but I still can't stop it!
"Good luck to the guy, though. I wish him well."
England went on to win 7-1 in what was Taylor's last game in charge, with Ian Wright scoring four goals. But it was a hollow victory.
To reach USA '94, England had been left needing to win their final game of a calamitous campaign by seven goals and hope Poland beat the Netherlands. The score at half-time in Poznan was 1-1 but Dennis Bergkamp put the Dutch ahead before the hour mark and Ronald de Boer's late goal extinguished all hope.
Back in Bologna's Stadio Renato Dall'Ara, where San Marino played their home games, England were by now well on their way to a one-sided victory but the mood was bleak.
"Nearly everyone in the ground was following what was going on in Holland's match," Taylor added. "In fact, it was difficult to stop people telling you what was happening.
"So there wasn't any enjoyment to be had from our game. We had beaten San Marino 6-0 at Wembley so we put 13 goals past them in total but we had still only done what people expected and, of course, we knew the Dutch had won too so we were out no matter how many we scored.
"It was a very hard trip and one of the worst aspects of it was that we flew back to Luton Airport and had to fight our way through the press and photographers.
"We had no security and no-one to meet us and we had to get our luggage and fight our way to our cars on our own. You wouldn't have that now - it's a completely different world.
"I was pushing against the photographers who were deliberately getting in the way of the trolley in the hope I would stop, but I kept pushing. I think I caught a few shins that day but, to tell you the truth, I was quite happy to because cameras were being shoved pretty much into my face."
Taylor resigned six days later. Things were turning out rather more happily for Gualtieri, meanwhile, who got Pearce's shirt as a souvenir at the final whistle but did not speak to any of the England players because "they were all a bit angry".
Gualtieri did not find out his goal was a world record until journalists told him after the game, and he did not realise he had made the front page of several British newspapers until he was sent a copy of the Daily Mirror, with the headline "End of the world" and his picture on it.
England team: David Seaman; Lee Dixon, Gary Pallister, Des Walker, Stuart Pearce; Stuart Ripley, Paul Ince, David Platt, Andy Sinton; Ian Wright, Les Ferdinand.
England scorers: Ince (21 mins), Wright (34), Ferdinand (38), Wright (46), Ince (63), Wright (78), Wright (90).
He has had plenty of attention since then, too, including more than 270,000 views of his goal on YouTube. Gualtieri, who also owns a video of the game, last watched it about six months ago but he is expecting it to get plenty more viewings this week.
Now 41 and a computer salesman in San Marino with a lot less hair than he had in 1993, he does not speak any English but, with his wife Caterina translating, I asked him how he became aware of what turned out to be an enduring fame - and a particular popularity with Scotland supporters.
Tales that Scottish fans paid for his drinks on a night out when they came over for a European Championship qualifier against San Marino a couple of years later turned out to be an invention, but Gualtieri's brother did benefit from some Caledonian hospitality.
"Over here, nobody really knew what was going on but in England there was a big fuss," Gualtieri explained.
"Even now, some fans from around the world are always coming into my shop with pictures of me and shirts for me to sign.
"And, when my brother went to Scotland on holiday, they found out who he was and bought him drinks and a meal too. But that was my brother, not me."
When I ask him which player he used to compare himself to, Gualtieri describes himself with a laugh as "a poor man's Roberto Baggio". But, despite only ever being a part-time player, he is a full-time member of footballing folklore, and will stay that way even if his record is eventually broken.


Chelsea's out-of-contract winger Gael Kakuta has joined La Liga side Sevilla.

Kakuta, 23, moved to Stamford Bridge from Lens in 2007 and was on loan at Rayo Vallecano last season, where he played 35 games.
The Frenchman played 16 times for the Blues, but spent time on loan at six different clubs.
In September 2009, Chelsea were barred from signing new players after being found guilty of inducing Kakuta to break his contract with Lens.
The ban was lifted by a court in February 2010 after the two clubs reached an agreement on his signing.
It is thought Sevilla have had to pay a fee for Kakuta because he is under 24.
In October 2014, failed footballer Medi Abalimba was sentenced to four years in prison after masquerading as Kakuta.
Manchester Crown Court heard Abalimba went on a £20,000 shopping spree at Selfridges, stayed at top hotels and even hired a helicopter.
