Author Steve Silberman has won the £20,000 Samuel Johnson Prize for Non-Fiction for his book about autism.

The judges said Neurotribes: The Legacy of Autism and How to Think Smarter About People Who Think Differently was a "tour de force" of journalistic and scientific research.
It is the first popular science book to win the prize in its 17-year history.
The shortlist had included Jonathan Bate's Ted Hughes: The Unauthorised Life and Robert Macfarlane's Landmarks.
Historian Anne Applebaum, chair of the judges, praised Silberman's "compassionate journalism" and said he excelled at using stories and anecdotes to explain complex medical issues to a wide audience.
The American author, who is based in San Francisco, has been a science writer for Wired and other magazines such as the New Yorker, the MIT Technology Review, Nature and Salon for more than 20 years.
"We admired Silberman's work because it is powered by a strongly argued set of beliefs: that we should stop drawing sharp lines between what we assume to be 'normal' and 'abnormal', and that we should remember how much the differently-wired human brain has, can and will contribute to our world," Applebaum said.
"He has injected a hopeful note into a conversation that's normally dominated by despair."
Neurotribes, she added, was "a tour de force of archival, journalistic and scientific research, both deeply researched and widely accessible".
In its review of Silberman's book, The Guardian described Neurotribes as "a gripping narrative written with journalistic verve".
The £20,000 Samuel Johnson Prize was won last year by Helen Macdonald's H is for Hawk.


Dunfermline ended promotion hopefuls Greenock Morton's year-long unbeaten run at home with a narrow Championship win at Cappielow.

Nat Wedderburn scored the only goal of the match after a mistake by Morton goalkeeper Derek Gaston.
The hosts pressed in the second half but found Pars keeper Sean Murdoch in wonderful form.
Callum Morris netted but the goal was disallowed for a foul by the Dunfermline defender.
Jim Duffy's side, who play leaders Hibernian on Wednesday, miss the chance to go second as they remain level with Falkirk and four points ahead of fourth-placed Dundee United while Allan Johnston's men are four above the relegation zone.
Morton were bright early on, Lee Kilday's header flying over the bar and Lawrence Shankland going clean through on goal only to be stopped by Lee Ashcroft's intervention.
But it was Dunfermline who went ahead. Kallum Higginbotham's corner was not dealt with at all by Gaston and Nicky Clark flicked the ball on to Wedderburn, who applied the tap-in and was booked for going into the crowd to celebrate.
Shankland was in on goal again following Mark Russell's pass but shot wide and Morton's Ross Forbes was booked for simulation in the Pars' penalty area.
Michael Doyle and Andy Murdoch were denied by Sean Murdoch as the home side searched for an equaliser.
And the Dunfermline stopper produced an impressive point-blank save to prevent Kudus Oyenuga scoring.
Gaston was also tested, doing well to keep Clark's effort out.
The Pars thought they had doubled their lead but Morris's header was chalked off for pushing.
It mattered little, though, as Dunfermline held on for the three points and bounced back from last week's home defeat by Ayr United while Morton can only reflect on a frustrating and disappointing day.
Dunfermline Athletic manager Allan Johnston: "It was an incredible record to go a full year unbeaten at home; it just shows you the consistency they've shown since the start of the season.
"Jim Duffy has done a great job here so we're delighted to come here and get the three points. The win is massive, but the work rate today was exceptional from not just the defence, but the midfield, the wide players getting back in, the strikers dropping back in, it was real team performance today."
Morton manager Jim Duffy: "It's extremely disappointing; a lot of aspects were below par. One or two individuals did ok but defensively I don't think we were anywhere near good enough.
"I think in midfield, the creativity was missing and up front I felt we lacked a spark. Credit to Dunfermline, they score from a mistake but overall, I don't think we can complain about losing that today.
"In open play I didn't feel we were quite calm enough in the final situation, and you've got to show that composure. That's the difference - top players show composure at key moments and I felt that when we got wide, we kind of rushed a cross, or scuffed a cross, things like that. Dunfermline deserved to win."

World Rally champion Sebastien Ogier has won the Wales Rally GB for a fourth successive year.

The 32-year old Frenchman finished 10.2 seconds ahead of second-placed Ott Tanak of Estonia.
Ogier secured his fourth consecutive WRC title in October, alongside his Volkswagen Motorsport co-driver Julien Ingrassia. His victory in Wales was his sixth of the season.
Belgium's Thierry Neuville was third at the end of the 22 stages.
Neuville is in contention for second place overall in the WRC.
Kris Meeke and Citroen co-driver Paul Nagle were the best British competitors in fifth place.
Wales' Osian Pryce was 19th after stage 19 at Alwen, but had to withdraw when he suffered a hole in a radiator on the approach to the 20th stage at Clocaenog.
The final round of the WRC starts in Australia on 17 November.


Two people, who were killed when two cars collided on a road in South Yorkshire in the early hours of Saturday were teenagers, police said.

A Vauxhall Astra and a Peugeot 206 were involved in the crash on Blackburn Road in Sheffield at 01:00 GMT.
A 19-year-old Rotherham man died in the Astra and a Sheffield man, also 19, died in the Peugeot.
One man, 20, was arrested on suspicion of causing death by dangerous driving and failing to stop at the scene.
Three other men who were travelling in the Peugeot were injured and taken to hospital for treatment.
They were a 24-year-old and an 18-year-old from Rotherham, and a 21-year-old man about whom no other details were released by police.
The nature of their injuries is not known.


Crawley Town have parted company with head coach Dermot Drummy by mutual consent after one year in charge of the League Two club.

Assistant head coach Matt Gray has also left the club.
Former Chelsea youth coach Drummy signed a two-year deal to replace Mark Yates as Reds boss in April 2016.
Crawley, who host Mansfield in their final game of the season on Saturday, are 21st in League Two and seven points clear of the relegation zone.
Drummy, who had no previous managerial experience in the EFL, won 15 of his 54 games in charge of the club.
A club statement said: "The club would like to thank Dermot and Matt for their hard work in the last 13 months and wish them all the best for their future careers."
BBC Sussex & BBC Surrey Crawley commentator John Barnett
"The appointment of Drummy, whose background was as a vastly experienced development coach, was an interesting one, not least in terms of the style of football he had pledged to instil.
"The early signs were promising, with the club reaching fifth place by mid-October and fans clearly appreciative of the brand of football on offer.
"Despite some poor away form, the home record remained strong into February, but once a losing sequence at the Checkatrade Stadium stalled their progress somewhat, the passing game seemed to abate.
"Just three wins since mid-January started to frustrate the supporters, and clearly Turkish owner Ziya Eren, who parts company with a second manager in little over a year.
"Drummy's contribution to matters off the field and the club engaging with its fans should not be overlooked, and some important groundwork and more has been laid in that respect."


Police have been called to deal with a small flock of sheep loose near Inverness city centre.

The animals were happily munching in the front garden of a house in Drummond Road close to its junction with the busier Culduthel Road.
Police received calls from members of the public who were both concerned for the sheep and seeking to reunite the animals with their owner.
Officers helped to have the sheep rounded up and returned to their home.
It is understood the animals are kept locally.


Arsene Wenger is a "specialist in failure", according to Jose Mourinho.

Media playback is not supported on this device
The Chelsea boss was responding to the Arsenal manager's claim that other Premier League bosses are playing down their title chances because they "fear to fail".
Chelsea hold a one-point lead over the Gunners at the top of the table.
"Unlike Arsenal, we sought success and tried to build it through a concept of the game using English players." November 2007, regarding Wenger's policies at Arsenal
"I think he is one of these people who is a voyeur. He likes to watch other people. There are some guys who, when they are at home, have a big telescope to see what happens in other families. He speaks, speaks, speaks about Chelsea." October 2005, after Wenger criticised Chelsea's transfer policy
Mourinho said: "If he is right and I am afraid of failure it is because I didn't fail many times. Eight years without silverware, that's failure."
Under Wenger, Arsenal have not won a trophy since the 2005 FA Cup.
"He's a specialist in failure," continued Mourinho. "If I do that in Chelsea, eight years, I leave and don't come back."
The Portuguese manager, who won the Premier League twice in his first spell as Chelsea manager between 2004 and 2007, has won league titles in four countries, as well as the Champions League with Porto and Inter Milan.
This is not the first time Mourinho has criticised Wenger, the Blues boss having described the Frenchman as a "voyeur" in 2005 after his rival questioned Chelsea's transfer policy.
"He likes to watch other people," said Mourinho in October 2005. "There are some guys who, when they are at home, have a big telescope to see what happens in other families.
"He speaks, speaks, speaks about Chelsea."
"He's out of order, disconnected with reality and disrespectful. When you give success to stupid people, it makes them more stupid sometimes." November 2005, after Mourinho called Wenger a "voyeur"
"I know we live in a world where we have only winners and losers, but once a sport encourages teams who refuse to take the initiative, the sport is in danger." August 2005, talking about Chelsea's tactics
Former England striker and Match of the Day presenter Gary Lineker said Mourinho had gone "over the top" with his latest remarks.
"Mourinho is out of order and wrong with Wenger comments," Lineker wrote on Twitter.
"He's won trophies galore all over the world, playing delightful football.
"Yes, Wenger hasn't won anything for a number of years, but he hasn't, until very recently, had the budget of others. Club is in great shape."
Ex-Manchester United and England defender Gary Neville also entered the debate on social media.
"Getting to the business end!" he wrote on Twitter. "Jose lobbing grenades out! Anyone going to take him on?"
Chelsea, preparing for Saturday's FA Cup fifth-round tie against Manchester City, host Arsenal on 22 March in a match likely to have a significant bearing on the title fight.

Mourinho has previously said his side are not contenders, describing the Blues as a "little horse" in the Premier League race.
Brendan Rodgers, manager of fourth-placed Liverpool, continued that analogy on Thursday by saying his side "may be the chihuahuas that run in between the legs of the horses" as they look to make a late challenge.
Wenger insisted the title was "Chelsea's to lose" but said Arsenal would "give everything" to win it.
"Many teams are in it and it will be very tight until the end," said the Frenchman, who became Gunners boss in 1996.  "We will absolutely give everything and if we don't do I will take responsibility for it."


A taxi driver who bribed a 13-year-old girl to take sexually explicit photos of herself and send them to him on Facebook has been jailed.

Paul Gorman, 46, offered Â£40 to the girl to supply indecent images.
She took the pictures on her mobile phone in the toilets of her school.
Gorman, of Kilwinning, was jailed for 15 months at Kilmarnock Sheriff Court and placed on the sex offenders register for 10 years.
Police were called after a family friend spotted suspicious Facebook messages between Gorman and his victim, who is now 15.
Officers raided his home in Kilbirnie and seized a laptop containing pictures of young children being sexually abused.
Computer forensics experts found Gorman had visited a website which hosted child sex images.
During his trial, Gorman admitted taking or making indecent images at a house in Dalry in May, 2014.
A jury found him guilty of causing a child to engage in sexual activity by photographing herself and sending him pictures, and asking her to make an indecent video.
Four charges of lewd and libidinous behaviour and sexual assault of the girl and her friend, also 13, were found not proven.


Police in China have formally charged a labour activist with disturbing public order, reports say, following one of the country's biggest strikes in years.

Lin Dong, who works at a labour dispute service, was charged with helping to organise protests, his colleague said.
Workers at the shoe factories in the southern city of Dongguan have been protesting for more than two weeks over their social security contributions.
The Taiwanese firm Yue Yuen makes shoes for brands like Nike and Reebok.
More than 40,000 workers in Dongguan, Guangdong province, had refused to report to work.
They had been pushing Yue Yuen's Taiwanese parent company, Pou Chen, for increased social benefits, compensation for overtime, housing benefits and a salary increase.
On Thursday, police detained Lin Dong and another activist, Zhang Zhiru, who was released a day later.
A majority of the workers have reportedly returned to the factories. However, details surrounding their return were not immediately clear.
Strikes are common in the city of Dongguan one of China's main manufacturing hubs, says the BBC's Martin Patience in Beijing.
But the scale and duration of this walk-out would have worried the authorities, fearing it could trigger wider social unrest, our correspondent adds.


You can preview the story of the coming election in London by focusing on just a fraction of the 73 constituencies in the capital.

That's because the election is won and lost in marginal seats - those which are winnable, by the BBC's definition, through a swing of 5% in the vote. They are the close contests.
Most but not all of the seats below are marginal. Nearly all are targets, identified by the parties as those they have to win to achieve their overall nationwide electoral dreams.
Sarah Teather was 29 - then Britain's youngest MP - when she won a by-election in 2003 for the Liberal Democrats at the height of the Iraq war.
She announced in late 2013 she wanted to move on. Labour claimed, naturally, it was because she knew she couldn't win.
Others put it down to her disillusionment with life in the Coalition, not least after she was moved from her position as children's minister in 2012.
Her successor as candidate is Ibrahim Taguri. In January, his party attempted to give him a boost in profile by making him the Lib Dems' 'race equality champion'.
For Labour, Dawn Butler is seeking to resume her parliamentary career and needs a swing of 1.5% to win.
The seat covers an area that is often described as the most diverse in Britain.
It was Labour-held with thumping majorities of over 20% in 1997 and 2001, but the story of expenses claimed on second homes is held to have done for Ann Keen in 2010.
Now the Conservatives' Mary Macleod faces a tall order in hanging on for more than one parliamentary term. A Conservative majority of just under 2,000 here would disappear with a swing of 1.8% to Labour's Ruth Cadbury, a Hounslow councillor.
Some might argue every time London's mayor Boris Johnson voices his suspicions that more Heathrow concrete is the Treasury's chosen way, it makes the coming task a little more difficult for Macleod.  She and her opponents, of course, talk up the economic and social value of Heathrow Airport as a major employer in the area.
Given the recent poll ratings, you have to start taking more seriously the possibility that the Liberal Democrats could lose this seat to their senior Coalition partners - despite a swing of nearly 6% being required.
The Blair revolution in 1997 benefited not just Labour. It also saw Liberal Democrats get a toehold in south-west London.
Tom Brake defeated Conservative Nigel Forman, who had been MP for 21 years, and he has held on ever since.
The Evening Standard reported on a leaked memo from Conservative chairman Grant Shapps 'urging' Tory activists in Carshalton and Wallington to campaign instead in neighbouring Croydon Central where Conservative MP Gavin Barwell is facing a difficult task to cling on.
This is likely to be one of the most closely fought contests, with Labour needing a swing of 2.9% to remove Gavin Barwell, a former senior Central Office staffer, who won the seat from Labour in 2010.
The Conservatives lost control of the council to Labour in last year's local elections and their campaigners are quite open about the threat posed by UKIP who polled 17.5% of the vote then in the wards which make up the Croydon Central constituency.
If those UKIP sympathisers are mainly former Tories, and if they do not intend to come back to the Conservatives this May, then Barwell's position looks precarious.
Having spent eight years as a London assembly member, watching the rise and fall of Ken Livingstone, Angie Bray knows that things can drop from your lap as abruptly as they land in it. She won in what was a three-way marginal in 2010, and the Lib Dem factor will be crucial.
An Ashcroft poll had her in trouble. An Evening Standard poll had her losing too.
Labour's candidate -who needs a swing of just under four percent to win it - is Rupa Huq, sociologist, writer and older sister of TV presenter Konnie.
What has added a more complex dimension to this battle is the recent apparent movement in support for the Greens. They have chosen Tom Sharman to contest the seat. He is the Green Party's national policy communications manager.
It was the demise of Michael Portillo in the ultra-safe neighbouring seat of Enfield Southgate which came to embody the 1997 Labour landslide. While that leafier constituency reverted to the Conservatives in 2005, the one-time Home Office minister Joan Ryan hung on in Enfield North until 2010 when she was defeated by Conservative Nick de Bois.
She publicly challenged Gordon Brown's leadership in 2008 and was sacked as a vice chair of the party. She said boundary changes counted against her, but there was also the matter of the money she'd spent sprucing up her then 'second home' in the constituency, at the time fully within the rules but inviting questions. She later paid back about Â£5,000.
But it has led to some wondering whether it was a wise choice for Labour to re-select her to try to win the seat back in 2015.  That said, she must be favourite at this stage to restrict Nick de Bois to one term, given a swing of just 2% is needed.
Last time round this was a key target for the Conservatives. They had been in charge of the borough council, promoting an aggressive cost-cutting agenda and lopping pounds off their residents' council tax bills year on year. David Cameron had let it be known this was his favourite council. However Labour's Andy Slaughter won with a majority of over 7%.
Then, Labour won back control of Hammersmith & Fulham last year after a campaign which focused on threats to local hospital provision, estate regeneration and affordable housing.
The demographics are changing rapidly here and huge developments at Westfield, White City and Earl's Court look set to entrench the area as a haven for professional middle class couples who long ago recognised they had no chance of settling in Westminster, Kensington or Chelsea. The Tories have chosen a local councillor, Charlie Dewhirst, to try to achieve the 3.8% swing needed to win.


Police in Londonderry are seeking to trace two men in relation to a robbery connected to the death of 25-year-old Conall Kerrigan.

The Claudy man was found dead in the city centre on Sunday 23 August.
The robbery occured at around 02.34 BST on Sunday 23 August on the Derry walls at Bank Place leading to Foyle Street.
"We do not believe Conall's death was a result of a crime, however, we believe that his wallet was stolen before his death," said Det Insp Conor McStravick.
He added that no wallet was found on Mr Kerrigan, but was found sometime later after extensive searches.
Mr Kerrigan had been at the Metro Bar in the city earlier, but left and was later seen on the city walls.
He was last seen on the walls near Foyle Street at around 03.03 BST on 23 August.


One of the highlights of the Royal Family's summer calendar got under way on Tuesday, with the opening of Royal Ascot.

Temperatures were so hot that members of the public were allowed to remove their jackets for the first time in the event's history.
But the first day of the annual racing festival started on a sombre note as Her Majesty led a minute's silence to remember the victims and those affected by recent tragedies.
She was joined for a day at the races by senior members of the Royal Family as the temperature rose well above 30C.
Prince William went to the races with the Duchess of Cambridge, who wore an Alexander McQueen dress with a bespoke hat.
Prince Charles and the Duchess of Cornwall arrived during the Royal Parade, after the Queen, before the start of racing.
Former England rugby player Mike Tindall, who is married to the Queen's grand-daughter Zara Tindall, enjoyed a joke with some of the younger royals, including Prince William, Princess Beatrice, and the Duchess of Cambridge.
The Princess Royal joined the Cambridges along with the Earl and Countess of Wessex.
Prince Andrew was seen enjoying a joke with his sister-in-law the Countess, as Prince Charles and the Duchess of Cornwall chatted to a guest.


A mother arrested on suspicion of killing her two-year-old daughter in a crash in Birmingham has been released without charge.

The 22-year-old woman's car hit a tree in Gibbins Road, Selly Oak, on Thursday at 15:55 BST.
She was held on suspicion of causing death by dangerous driving and child neglect.
West Midlands Police said the woman would be interviewed in connection with the collision at a later date.
She was one of four people who had been travelling in the car and needed treatment following the crash.
West Midlands Ambulance Service said the toddler was confirmed dead at Birmingham Children's Hospital.
A post-mortem examination would take place in due course to determine the precise cause of death, police said.
The child's uncle, Brendan O'Reilly, said she "was always smiling, and never stopped smiling - she was a happy-go-lucky little girl".
He said the last time he had seen the girl was the night before the collision, when she had been her usual happy self.
"She had beautiful blue eyes," he said. "I cannot believe it."
Henna Rai was one of several members of the public, including a medical student, who tried to resuscitate the child at the roadside.
In tears, she returned to the scene on Friday clutching a bunch of flowers.
She said: "We were trying to resuscitate her, and I gave her mouth-to-mouth. A doctor came over to help.
"I just held her, and just wanted her to make it through. When I held her, I saw my own daughter - she was so peaceful."


Iraqi forces have retaken the main government offices in Mosul as the offensive continues to oust the so-called Islamic State (IS) group.

The advance could pave the way for an attack on the heavily populated old city, where the militants are still entrenched.
Thousands of civilians are streaming out of the city every day.
Mosul is the last stronghold for IS in Iraq.  The east of the city was recaptured in January.
The Iraqi forces launched a surprise attack overnight to storm the government buildings.
Although the structures are reported to be largely destroyed, they are a strategic and symbolic win.
The forces have also captured the central bank's main branch, which was looted by IS when they took over the city in 2014, and the nearby courthouse.
The court was used by IS to deliver harsh sentences, including stonings, throwing people off rooftops and chopping off hands, according to Reuters news agency.
On Sunday, Iraqi forces began a new push into the western part of Mosul after bad weather slowed them down.
The following day, they captured the al-Hurriya (Freedom) Bridge over the River Tigris.


Labour is effectively two political parties, due to the split between its MPs and wider membership, ex-Labour First Minister Rhodri Morgan has said.

It follows 66 Labour MPs voting to extend air strikes to Syria, a policy opposed by party leader Jeremy Corbyn.
Mr Morgan told BBC Wales most party members were "very loyal" to Mr Corbyn and "few" backed wider military action.
But he said most Labour MPs were "not really Corbynistas", so the party was having to deal with a "new phenomenon".
Speaking on the Good Morning Wales radio programme, Mr Morgan said: "In effect we have two Labour parties and this is a bit of a new phenomenon, so we've got to try to let it settle down and work out what's the best way forward."
Mr Morgan called a suggestion by the Labour MP and former minister Frank Field that the party should have two leaders was "quite clever" but "not very workable".
Mr Morgan's comments came as Labour celebrated victory in the Oldham West and Royton by-election.
Deputy party leader Tom Watson called the result "very, very good" for Mr Corbyn, and urged MPs to "swing behind" their leader after a "difficult week".


Former Arsenal, Fulham and Aston Villa defender Philippe Senderos is training with Rangers.

Ibrox boss Mark Warburton is keen to add a defender to his squad before the transfer window closes this month.
Swiss international Senderos, 31, most recently played his club football with Grasshoppers in his homeland.
"He is training for a week with us," Warburton told the Rangers website. "He is a very talented player with a very impressive CV."
Capped 57 times, he has played in three World Cup finals and a European Championship.
His spell with Grasshoppers last season followed an injury-hit 18 months at Villa.
Senderos, an FA Cup winner with Arsenal in 2005, has made over 200 senior club appearances.
"It is a case of he has not been training with a team so he is in for a week with us and nothing more than that," added Warburton.
"He looks very good technically from his background and physically he looks in good shape so we will have him in for a week and then see what that leads to."


National League club Eastleigh have confirmed they will not be renewing the contracts of eight first-team players.

The Spitfires, who reached the FA Cup third round this season, missed out on a place in the promotion play-offs.
Lee Cook, Josh Payne, Lewis Noice, Paul Reid, Kaid Mohamed, Jack Midson, Will Evans and Matt Fanimo have all been released by the Hampshire club.
New deals, however, have been offered to Andy Drury, Jamie Turley, Ben Strevens and Yemi Odubade.


A Bafta-nominated actor has been charged with possessing a fake firearm.

John McEnery, 73, was arrested after reports of a man with a gun at the Leading Light pub in Preston Street, Faversham at 08:20 BST on Tuesday.
Armed Kent Police officers were deployed and a man was arrested just before midday in Faversham Creek.
The former husband of Stephanie Beacham, Mr McEnery, of no fixed address, appeared in Girl with a Pearl Earring and Merlin.
Mr McEnery is due to appear before Maidstone Magistrates' Court on 25 August.
He has been charged with possessing an imitation firearm with intent to cause fear of violence.
Mr McEnery, who was born in Birmingham, joined the National Theatre Company in 1966.
He was nominated for a Bafta for best supporting actor for his portrayal of Mercutio in Franco Zeffirelli's 1968 film version of Romeo and Juliet.
The actor was married to Dynasty star Ms Beacham and the couple had two children before they divorced in 1978.
Hollyoaks and Ballykissangel actress Kate McEnery is the daughter of his actor brother Peter McEnery and Julie Peasgood.


A man has died after being shot in the head in a suspected ambush in west London.

The 24-year-old was found at about 21:30 GMT on Monday and pronounced dead after shots were reportedly fired near restaurants on Walham Grove in Fulham.
Police believe the victim, who was with a friend, had stopped for something to eat at a fast food restaurant.
The Met said "it would appear that the gunman had been lying in wait" for the pair to return to their car.
The victim was shot as he was getting into the front passenger seat of the silver and black Renault Captur.
The man has not been formally identified and a post-mortem examination will take place in due course, police said.
Detectives from the homicide and major crime command are investigating, but no arrests have been made.


Nottingham Forest midfielder Ben Osborn says the manner of their defeat by Wigan in the third round of the FA Cup was "embarrassing".

The Reds were beaten 2-0 as they suffered a fifth successive defeat.
Osborn, 22, told BBC Radio Nottingham: "It was shocking, especially in the second half. It was two teams low on confidence in the first half.
"They grew in the second half. At times they were playing around us and I felt embarrassed out there at times."
Fellow Championship strugglers Wigan had lost their previous six home matches, but eased their way into Monday's fourth-round draw.
Osborn continued: "Everyone is trying to come together. I just think 50-50 battles on the pitch, they won the majority, which has been the same in recent weeks.
"At the moment, we think we are better than we are. We need to go back to basics, we need to be disciplined and hard to break down, instead of being absolutely all over the place."


The UK has been found to be in breach of EU laws over the amount of sewage and waste water discharged into the sea off Carmarthenshire.

Overflow pipes at the Burry Inlet near Llanelli are used to help stop flooding.
But the European Court of Justice ruled this broke clean water laws in a special conservation area.
The Welsh Government, Natural Resources Wales and Welsh Water said they were investing in improvements.
Though the UK has not been fined, it will have to pay legal costs in a case that also found a number of other breaches around the handling of waste water in England and Gibraltar.
The problems stem from the UK's ageing Victorian sewers, engineering marvels of their time, but now out of date.
The pipes were designed to mix both sewage and rainwater but over the years new housing developments and more frequent storms as a result of climate change have put pressure on the system.
Welsh Water has 3,000 special overflow pipes which act as relief valves to deal with the extra sewage and rainwater but go straight into rivers and the sea.
At the Burry Inlet there are 14 overflow pipes which discharge into an area supposed to be protected by UK and EU laws.

The local cockling industry has also been hit but Welsh Water insisted this was not due to their discharges.
It is investing in a Â£113m project to reduce the number of spills.
RainScape involves reducing the amount of water that reaches the sewers through planting green spaces on streets and roofs to absorb rain and building channels to capture surface water.
The UK argued the improvements would mean it could comply with EU clean water laws by 2020.
However, the ECJ - which rules on disputes involving EU legislation - found the UK had acted "too late" and was failing in its obligations.
Judges ruled spills contributed to the deterioration of water quality in the Loughor Estuary.
A Welsh Government spokesman said: "We will continue to work with Natural Resources Wales and Dwr Cymru on a Â£113m programme to reduce the number of spills, improve water quality and reduce the risk of local flooding by 2020."
Welsh Water added: "We have met the legal permits for water quality in the Loughor estuary and are aware of ever increasing environmental standards and the need to manage long-term challenges, such as climate change, in a truly sustainable away."
The UK Government said all sites in England included in the judgement "now comply with the directive and plans are in place elsewhere across the UK to deliver compliance by 2020 at the latest".


The animator who co-created the 1980s children's TV hit Trap Door has died.

Terry Brain, from Bristol, "passed away peacefully" on Friday morning, at the age of 60, after a two-year battle with cancer, his son David Brain said.
"He was my hero - an amazing guy, funny. Right up until the last time I saw him... he was still trying to crack jokes through it," he said.
Along with fellow animator Charlie Mills, he was also behind Stoppit and Tidyup.
The pair were referred to as "Brainbox Mills".
Paying tribute to his father, Mr Brain said: "Dad was a smiley, relaxed person - and a veteran in the industry, who inspired many young animators."
He added: "Right up to the end he was making his own series in his spare room.
"He was four seconds of animation away from finishing a 12-part series he'd been doing, and we're going to try and get someone to finish it off for him. So there's still more to come.
"He wouldn't have wanted people to know he was in pain, just enjoy his stuff."
The animator, from Fishponds, was discovered by television artist Tony Hart, and joined his programme Hartbeat.
After working across the road from Bristol-based Aardman Animation, he joined them and worked on some of their biggest hits, including Shaun the Sheep, Chicken Run and Wallace and Gromit.
Mr Brain said: "Making people laugh was his priority. And if you look at his work, Trap Door and stuff, people grew up with it and see it as a kids show - but if you watch it now, you see the adult and risquÃ© humour in it, and that was the humour my dad brought with him."
A total of 40 episodes of Trap Door were produced, starring a blue-coloured character named Berk and a cast of monsters.
The animator had two children and three grandchildren.


JK Rowling has told an inquiry into media ethics of the scale of media intrusion into her private family life.

The Harry Potter author said a reporter had once tried to contact her by slipping a note into her five-year-old daughter's schoolbag.
She said clearly she could not put an "invisibility cloak" around her children to protect them.
Earlier, Lord Justice Leveson heard from actress Sienna Miller and former motorsport boss Max Mosley.
The inquiry, which is being held at the Royal Courts of Justice, heard:
Ms Rowling told the inquiry that children deserved privacy and that she had always tried to protect her private family life from the press, by taking measures which included wrapping them in blankets to hide them from paparazzi.
"They (children) have no choice over who their parents are or how their parents behave.
"A child, no matter who their parents are, deserves privacy. Where children are concerned the issue is fairly black and white."
By Peter HuntRoyal correspondent
A harsh and unforgiving light has been shone this week on some of the practices of the popular press.
The complainants have included those who chose fame and those who were flung out into the public glare.
All have detailed their woes at the hands of reporters and many have spoken of the power of newspapers and the strength needed to take them on. As JK Rowling put it, if you fight back against certain sections of the press, you can expect retribution.
The problems have been highlighted, but what of the solutions? Workable ones, which will please everyone, are so far thin on the ground.
The litany of malpractices will continue next week. More people who believe they have been wronged in the past will give evidence to Lord Justice Leveson in the hope he'll put it right for the future.
Witness statements
She said that when her daughter was in her first year at primary school, she unzipped her schoolbag one evening and "among the usual letters from school and the debris that a child generates, I found a letter addressed to me and the letter was from a journalist".
She added: "I felt such a sense of invasion that my daughter's bag.. it's very difficult to say how angry I felt that my five-year-old daughter's school was no longer a place of complete security from journalists."
The author also recalled how the PCC found in her favour after a photograph of her eight-year-old daughter in a swimsuit on a beach in Mauritius was published in OK magazine.
"I feel that given fact that an image has a life that cannot be recalled... I'm sure it is still out there, that's the particular harm of an image."
The writer said shortly after her son was born she was besieged by photographers.
After a week had passed she believed they had disappeared so she decided to leave the house and take her children out, however she soon realised that a photographer with a long lens was there.
"I rather absurdly gave chase. How I thought I was going to outrun a 20-something paparazzo while pushing a buggy. The cumulative effect, it becomes quite draining."
The author also told the inquiry how she had to sit down with her daughter to say an unpleasant character in a Harry Potter book was not based on her ex-husband, which was a "wholly untrue" story the Daily Express had published.
Ms Rowling then went on to discuss how she had been 'blagged', which is when somebody unknowingly reveals personal information.
She said in one instance shortly after she had moved house she received a phone call from somebody purporting to be from the Post Office saying they had a package for her and wanted to confirm her address.
"When I was blagged I realised half-way through giving the person details that I was being blagged," she said.
"This man said to me 'I am from the Post Office, I've got a package for you, what's your address?' Then I said 'Wait! You're from the post office, well what does it say on the package?' and he hung up."
Ms Rowling also said her then boyfriend (now husband) was duped by a journalist who pretended to be from the tax office into giving out personal information.
"He gave them everything - address, pay grade, National Insurance number. The next day flashes went off in his face - the paparazzi had found him."
The author added: "Like a lot of people who have agreed to give evidence at this inquiry, we are not asking for special treatment.
"We are simply asking for normal treatment... and I am simply asking for that on behalf of my children."
Ms Rowling confirmed she had not been a victim of phone hacking as "she hardly used her phone in the 90s".
Mr Mosley, who had won Â£60,000 in damages from the News of the World after a judge ruled that its story about his sex life had invaded his right to privacy, earlier told the inquiry of his outrage that photographs of him at a sadomasochistic orgy were published.
He said his son, who has since died, resumed taking drugs as he could not cope after seeing the photographs.
Mr Mosley also said a second story, purporting to be the account of a woman who had filmed the orgy, was later found to have been written by News of the World reporter Neville Thurlbeck, who he said had forced the woman to put her name to it.
Earlier, Ms Miller - who has been the subject of media attention for her relationships with partners such as actor Jude Law - told the inquiry about incidents where she said paparazzi had driven dangerously and illegally while following her.
She questioned why having a camera made it legal for people - sometimes as many as "10 to 15 men" - to chase her. "I would often find myself - I was 21 -  at midnight running down a dark street," she said.
In his evidence, lawyer Mark Thomson - who has represented celebrities including Jude Law and Lily Allen - argued for a stronger regulatory system for the press.
"I really don't think that just a few adjustments to the PCC (Press Complaints Commission) will work," he said. "Some of the worst offenders are photographic agencies and paparazzi, and the PCC can't control them."
Lord Justice Leveson's inquiry is looking at the "culture, practices and ethics of the media" and whether the self-regulation of the press works.
A second phase of the inquiry will commence after the conclusion of a police investigation into News of the World phone hacking and any resultant prosecutions. It will examine the extent of unlawful conduct by the press and look at the police's initial hacking investigation.


The mayor of Buenos Aires has announced that his administration has taken over the running of the city's zoo after a series of scandals about the condition of its animals and buildings.

It will now become an eco-park promoting environmental conservation.
Its 2,500 animals will be moved to sanctuaries in other parts of Argentina and abroad where they can be housed in better conditions.
Mr Larreta said the animals had been living in degrading conditions.
The zoo has been in existence since 1875, run by a private company which won a concession to manage it.
The zoo attracted very bad publicity in recent years, particularly over the inadequate conditions in which its polar bears were kept during the city's oppressively hot summers.
The last polar bear, called Winner, died three and a half years ago during a particularly hot season.
Among the 50 animals who will stay behind because they are too fragile to move is Sandra, an Orang-utan who made headlines two years ago.
Animal rights activists  won a legal case in which she was granted the status of a  "non-human with rights" after concerns were raised about her health and living conditions.


A popular arts project which brought 50 life-sized fibre glass dolphins to Aberdeen is drawing to a close.

The Wild Dolphins project was organised by Wild in Art along with the Archie Foundation at the Royal Aberdeen Children's Hospital, and Whale and Dolphin Conservation (WDC).
For the last 10 weeks they have been the most photographed and talked about attractions in the city.
They were in parks, shopping centres, the beach and museums.
The models will now be auctioned.
The auction will be held at Aberdeen's Music Hall on Wednesday 10 September from 19:00.
Proceeds will be split between Archie and WDC.


Air pollution in some parts of London has been so bad recently, that the Mayor of London has decided to use the highest pollution level alert for the first time.

Part of a railway line in Gwynedd remains closed over damage caused by Storm Doris.

Engineers were working to repair the line over the weekend after a tree fell onto the track between Llanrwst and Blaenau Ffestiniog on Thursday.
But the work uncovered unstable rocks by the track, requiring extra work.
Arriva Trains Wales said a replacement bus service between North Llanrwst and Blaenau Ffestiniog would run until Friday.


German carmakers have agreed with top politicians to cut harmful emissions by updating software in five million diesel vehicles.

New engine management software will improve emission filtering systems and cut toxic nitrogen oxide levels by 25-30%, the industry association VDA said.
The industry is under pressure since a diesel emissions scandal exposed cheating to manipulate test readings.
Talks continued after the deal was announced, a source told Reuters.
The deal was struck at a summit in Berlin.
It was approved by Daimler, BMW, Volkswagen and Opel, VDA said in a statement (in German).
Car firms are a crucial part of the German economy, providing more than 800,000 jobs.
Shortly after the deal was announced, a source close to the negotiations told Reuters that talks between several cabinet ministers, regional premiers and car bosses were still going on at group level.
Pressure to cut emissions increased last week, when a court in Stuttgart upheld a proposal to ban older diesel cars from the city.
It is the home city of Mercedes and Porsche, and one of Germany's pollution hotspots.
The BBC's Jenny Hill in Berlin says air pollution now regularly exceeds legal limits in many German cities. It is a headache for the mighty automotive industry and for German politicians, ahead of a 24 September general election.
But Germany is unlikely to commit to ending production of combustion-engine vehicles any time soon, our correspondent says.
France and the UK plan to ban sales of fossil-fuel vehicles from 2040.
But switching to a future of electric vehicles will be hugely expensive - not least because of the need for charging points everywhere.


Up to 3,000 elderly people will not be able to get beds in UK care homes by the end of next year, research suggests.

Research commissioned by BBC Radio 4's You and Yours programme reveals a huge shortfall in the number of beds available.
Increasing demand from an ageing population could see that grow to more than 70,000 beds in nine years' time.
The Department of Health said local authorities in England had been given an extra Â£2bn to help fund social care.
But in the past three years one in 20 UK care home beds has closed, and research suggests not enough are being added to fill the gap.
Worries over care home fees and funding
How to choose the perfect care home
The research, carried out by property consultants JLL, found that since 2002 an average of 7,000 new care home beds had opened in the UK every year, but by 2026 there would be an additional 14,000 people needing residential care home places per year.
Lead researcher James Kingdom said: "We're currently building half the number of care home beds every year that we need."
"There are more people living longer.
"We know that over the course of the next decade there is going to be 2.5 million more over-65s, and as a result that means there is going to be demand for care home beds.
"To fix that, we need to double the rate of delivery".
Barchester Health Care is the third largest care home provider in the UK.
It is concerned the gap in capacity means extremely vulnerable people are not getting the care they need.
Chief executive Pete Calveley told You and Yours: "Increasingly, highly dependent people are left at home.
"We feel that leaves them socially isolated and doesn't meet their needs.
"So, one of the ways they reduce demand is by raising the criteria, which I don't think is always appropriate."
But the Association of Directors of Adult Social Services says there is a risk too many people are being placed in residential care.
The association's president, Glen Garrod, said: "There is a danger of looking to residential options when we haven't fully exhausted all those that might help people stay at home - which is where most people would prefer to be."
In the past three years, 21,500 care beds have closed in the UK.
People in the care industry worry that as bed capacity decreases and demand increases, there will be more pressure on NHS beds as elderly people are admitted to hospital because they can't cope at home.
The government estimates this already costs the NHS in England Â£900m a year.
Pete Calveley, from Barchester Health Care, said it was an increasing feature of the health and social care environment because there was not enough capacity in the community.
The Department of Health said high quality care was not just about providing care home beds.
A Department of Health official said 61% of people "are cared for in their own home, and since 2010 there has been a growth in home care agencies of more than 2,900".
"We've given local authorities in England an extra Â£2bn boost over the next three years to maintain access for our growing ageing population and to put the social care sector on a sustainable footing for the future."


A man has been jailed for eight years for his part in what has been described as the most serious fake medicine fraud in the European Union.

Peter Gillespie, 64, from Hertfordshire, was part of a £4.7m plot to bring two million doses of counterfeit drugs from China to the UK.
He was convicted of conspiring to defraud pharmaceutical wholesalers, pharmacists and members of the public.
He was convicted by a jury at Croydon Crown Court.
By mimicking authentic, properly manufactured and tested medicines, Gillespie illegally infiltrated the regulated system designed to protect the public and pharmaceutical industry, the court heard.
The counterfeit medicines contained only a fraction of the correct dosage.
They included Zyprexa, a medicine to treat schizophrenia and bipolar disorder.
Andrew Marshall, prosecuting, said patients had been put at risk by his fraud.
"This case is considered to represent the most serious breach of the medicine control regime - it's the most serious breach that has happened in the EU," he told jurors.
"It has had far-reaching effects for the pharmaceutical industry, control mechanisms, patients and the confidence of the public."
The case arose from a £750,000 three-and-a-half-year investigation by the Medicines and Healthcare products Regulatory Agency (MHRA).
Mick Deats, head of enforcement, said after the trial that 72,000 packs of counterfeit medicine - with a retail value of £4.7m - penetrated the UK supply chain between December 2006 and May 2007.
Some 25,000 of these packs reached pharmacies and were given to patients.
The MHRA was able to seize 40,000 before they got to pharmacies, and 7,000 were recovered following recalls.
Although the drugs contained just 50% to 80% of the correct ingredients, Mr Deats did not believe they caused any fatalities or adverse reactions.
At Croydon Crown Court, Gillespie, of High Street, Bovingdon, was also found guilty of selling or supplying drugs without a marketing authorisation  between January 2006 and June 2007.
Jurors also found him guilty of a charge of acting as a company director while disqualified.
Mr Deats added the MHRA now hoped to seize anything Gillespie obtained through his scam in a proceeds of crime hearing.
Four other men - his brother Ian, 59, of The Green, Marsh Baldon, Oxfordshire; Richard Kemp, 61, of School Lane, Y Waen, Flint, north Wales; Ian Harding, 58, of Lower Westwood, Bradford-on-Avon, Wiltshire; and James Quinn, 70, of Virginia Park, Virginia Water, Surrey - were acquitted of all charges.
Another person connected to the case had already been convicted in the US.


Ahmad Jarba, the new head of the National Coalition for Syrian Revolutionary and Opposition Forces, is an influential tribal figure who has close links to Saudi Arabia.

Mr Jarba, a Sunni Muslim, was born in 1969 in the north-eastern Syrian city of Qamishli, in Hassakeh province. The province is home to Arabs and Kurds.
He is a member of the Shammar tribe, one of the most prominent tribes in eastern Syria. The Shammar also has a presence in Iraq, Saudi Arabia and Jordan.
Mr Jarba was politically active in the 1990s and was imprisoned between 1996 and 1998 for opposing President Hafez al-Assad.
He was jailed again in March 2011, at the start of the current uprising, for supporting pro-democracy protests. Mr Jarba left for neighbouring Lebanon that August, after his release.
He has subsequently spent time in Saudi Arabia and is believed to maintain close ties with the Gulf kingdom's leadership. Saudi Arabia is a leading source of support for the Syrian opposition.
Mr Jarba has played a vital role in bridging the gap between tribes in eastern Syria and the opposition.
He is close to the faction of Syrian secular dissident Michel Kilo, who has sought to gain the support of minority groups in the face of a possible Islamist takeover.
Mr Jarba was a member of the opposition Syrian National Council (SNC), before joining the coalition.
He suspended his membership of the National Coalition in March 2013, following its appointment of Ghassan Hitto as prime minister of the organisation's interim government. Mr Jarba went on to help administer rebel-held areas.
According to the National Coalition's Facebook page, Mr Jarba "has been supporting the Syrian revolution, providing medical and military aid, since the beginning of the revolution". He has also been a "key figure in establishing political diplomacy", it says.
In recent months, Mr Jarba has been a leading advocate of providing arms to the opposition forces.
Although he often wears a Western-style suit and tie, some of Mr Jarba's official photographs show him wearing the traditional robe worn by Arab tribesmen.

Tributes have been paid to Emmanuelle Riva, the veteran French actress who has died of cancer aged 89.

French president Francois Hollande said the actress "created intense emotion in all of the roles she embodied".
Born in 1927, Riva found worldwide fame when Alain Resnais cast her in his 1959 romance Hiroshima Mon Amour.
Fifty-four years later, she became the oldest ever nominee for the best actress Oscar when she was shortlisted for her role in Michael Haneke's Amour.
The film cast her and Jean-Louis Trintignant as an octogenarian Parisian couple whose life together is rocked when her health suddenly declines.
Though Riva lost out to Jennifer Lawrence, she received numerous other accolades and enjoyed a late-career revival as a consequence.
The Academy of Motion Picture Arts of Sciences tweeted a tribute on Saturday and thanked the actress "for all that you've given us".
Riva's 60-year career spanned film, TV, and theatre, which saw her work with a number of celebrated European directors.
They included Poland's Krzysztof Kieslowski, who cast her as Juliette Binoche's mother in Blue - the second instalment of his famous Three Colours trilogy.
Riva, who never married and had no children, received a Bafta, a Cesar and a European Film Award for Amour, named after the French word for love.
"A great and sublime actress has left us," said Alain Terzian, president of the body that presents the Cesar film awards.
According to her agent, Anne Alvares Correa, the actress died in Paris on Friday "after a long illness" who "was active until the end".

Her Majesty's Revenue and Customs (HMRC) is to close its regional offices in Northern Ireland and operate from a single facility in Belfast.

Offices in Newry, Coleraine, Craigavon, Enniskillen, Lisburn and Londonderry will close between 2016 and 2021.
HMRC said it is phasing the closures to "allow staff time to make choices for their future" and reduce redundancies.
It is part of a wider move which will see the agency consolidate its staff across 13 regional centres in the UK.
The closure of the Newry office had been announced last year.
In 2013, HMRC also began a voluntary redundancy scheme for some staff Enniskillen, Londonderry, Newry and Belfast.
HMRC expects between 1,300 and 1,600 full-time equivalent employees to work in the Belfast regional centre.
Lin Homer, HMRC's chief executive, said: "The new regional centre in Belfast will bring our staff together in more modern and cost-effective buildings in an area with lower rent.
"It will also make a big contribution to the economy of Northern Ireland providing high-quality, skilled jobs and supporting the government's commitment to a national recovery that benefits all parts of the UK."

England's "powerful" batting line-up gives them a strong chance of winning the World Twenty20, according to former winning captain Paul Collingwood.

Skipper Eoin Morgan, Ben Stokes, Jos Buttler, Alex Hales and Joe Root were part of successes against New Zealand, Australia and Pakistan in 2015.
Sam Billings, Jason Roy and James Vince complete coach Trevor Bayliss' options.
"With players like that, you'll always have a chance to win major tournaments," Collingwood said.
He told BBC Newcastle: "The fielding is world-class, the batting line-up is powerful right down to nine or 10. There are good things happening in this team."
Collingwood lifted the trophy as England skipper in 2010, when they beat Australia in the final in Barbados.
He will travel to India as part of the coaching staff and, although defeats by South Africa in both one-day and T20 cricket tempered the optimism among England supporters, he believes that should be regarded as "a bit of a blip".
The 39-year-old added: "Everybody has seen the way white-ball cricket has been going over the past year, it's been very exciting.
"We need to realise the good things they've been doing the past year, the way they've played their cricket, these guys are very much athletes now.
"If they play like they did against Australia or New Zealand they can beat anyone."
Hampshire batsman and captain Vince is also confident that England have the talent to be strong challengers.
The 24-year-old did not feature on the recent tour of South Africa, but he was part of the Karachi Kings team which reached the semi-finals of the Pakistan Super League in February.
"Although the South Africa series didn't quite go to plan, the way the guys have been playing their one-day cricket and Twenty20 cricket over the last 12 months or so gives us a real chance," he told BBC Radio Solent.
"We'll just go out there and play the way we can do, and if we do that we'll go somewhere."


Members of an indigenous group in Colombia say they have driven about 100 soldiers from the military base they were guarding in southwestern Cauca province.

The Nasa tribe had given the security forces an overnight deadline to leave.
They say they are tired of being caught in the middle of confrontations between the army and members of Colombia's largest rebel group, the Farc.
The army said it had moved its men temporarily to avoid further clashes.
Army commander General Alejandro Navas said the soldiers were still on the mountain where they were based, but had moved further down its slope.
Local media described how some 1,000 Nasa surrounded the army post, grabbed one of the soldiers and carried him 10m (35 feet) down the mountain.
A soldier fired into the air to disperse the Nasa, who in turn threw soil at the armed forces.
The Nasa say 250 of them will stay on the top of the mountain to prevent the soldiers from returning.
Tension between the security forces and the indigenous groups around Toribio, in Cauca province, have been growing for the past week.
After days of attacks by Farc rebels on the police station in Toribio, the Nasa demanded the security forces and the rebels take their fight elsewhere.
They dismantled trenches erected by the security forces. They also marched on a rebel camp in the mountains and told the Farc to leave.
Defence Minister Juan Carlos Pinzon said the security forces would stay in the area and continue fighting the Farc.
Mr Pinzon said the government would continue dealing with the indigenous population through "dialogue and respect", but warned them not to break the law.
The steep mountainous area is a Farc stronghold and a key corridor for the trafficking of cocaine.
Indigenous groups say they are bearing the brunt of the fighting between the government forces and the rebels.
They say the presence of the security forces attracts the rebels, whose mortars often miss their intended targets and kill civilians.
They want to assume control of the area and guard it themselves.


Shares of burger and milkshake chain Shake Shack sank by as much as 15% in after-hours trading after it posted an unexpected sales decline.

The fast food company said revenue at existing stores fell 2.5% after cold weather in the US Northeast hurt sales.
Profits were $2.3m (Â£1.8m) in the quarter, up 55% year-on-year.
Chief executive Randy Garutti said the firm was still expecting strong overall growth in 2017, but conceded: "We are clearly dissatisfied."
The New York company expects new stores to help fuel growth.
Shake Shack, which started as a hot dog stand in a Manhattan park and quickly grew a cult-like following, has already opened two shops in London this year.
It plans to open up to 36 new sites globally in 2017, adding to its more than 100 locations around the world.
Shake Shack was not the only US food company reporting weaker-than-expected sales on Thursday.
Dunkin Donuts said its sales at established stores in the US were flat. Net income rose 28% year-on-year to $47.5m.
The results came amid an "increasingly challenging environment for retail and restaurants," Dunkin' Brands chief executive Nigel Travis said.


Dan Biggar scored all 19 points as Ospreys maintained their lead at the top of Pool 2 in the European Champions Cup with a hard-fought win over 14-man Bordeaux-Begles.

Bordeaux led at the interval through Felix Le Bourhis' try but Biggar's three penalties kept Ospreys in touch.
Jean-Baptiste Dubie was sent off for a high tackle on Biggar, whose converted try put Ospreys ahead.
The French side never gave up and secured a losing bonus point.
Bordeaux made 13 changes from the side that had beaten Stade Francais the previous week while Alun Wyn Jones, Dan Lydiate, Biggar and Scott Baldwin retuned to the Ospreys line-up.
Biggar gave the Ospreys an early lead with a penalty from in front of the posts, but Pierre Bernard succeeded with a kick of his own to level two minutes later.
Both sides showed intent to move the ball during the opening period with Biggar intercepting opposite number Bernard's pass, but did not have the pace or support to threaten the try line.
The Wales fly-half restored the home side's lead with his second penalty of the game but Bernard's second kick brought Bordeaux level.
Ospreys were reduced to 14 men when captain Jones was shown a yellow card for dragging down a driving line-out as the visitors pressed.
Bordeaux-Begles took full advantage of Jones' absence when, following a rolling maul, Felix Le Bourhis scored on the overlap to cross for the opening try.
Bernard added the conversion, although Biggar's third penalty reduced the deficit to four points before the interval.
Ospreys reduced the gap to a single point two minutes into the second half with Biggar maintaining his 100% kicking record with a fourth penalty.
Biggar was on the receiving end of a late high tackle from Dubie, who was sent-off following a TMO review.
Reduced to 14 men, Bordeaux-Begles were further punished when Brendon Leonard sent Biggar over to cross in the corner before converting the try.
Despite their numerical disadvantage the visitors dominated the next 10 minutes and came within inches of the Ospreys try line, but the home side's defence stood firm.
Romain Lonca replaced Bernard and his first contribution was a successful penalty, however a second kick - which would have levelled the scores - went wide.
The second half did not reach the levels of the opening 40 minutes and Bordeaux finished the game with 13 men after prop Jean-Baptiste Poux was given a yellow card.
The sides meet again in the return match in France on Saturday, 19 December.
Ospreys forwards coach Chris Gibbes told BBC Radio Wales:
"Happy to get the result but the performance was below-par. We got caught out in a few areas around the line-out and it cost us.
"A lot of respect has got to be paid to them. They were down to 14 men and they didn't change and they kept coming at us and really put us under pressure.
"It's going to a tough place to go next week but we believe we can do it."

The chief executive of the Belfast-based Wireless Group, which was formerly UTV Media, is to retire.

John McCann became chief executive of UTV Media in 1999 and led the expansion of its radio operation. He will retire at the time of the annual general meeting in May.
The group completed the sale of its TV assets to ITV this week and is now effectively a radio business.
The Wireless Group will now be led by Richard Huntingford.
Mr Huntingford is currently non-executive chairman and will become executive chairman.
Helen Kirkpatrick, senior independent director, said: "On behalf of all shareholders and employees of the company, I would like to thank John for his outstanding leadership, professionalism and passionate commitment to the UTV Media plc cause over so many years.

Sussex resumed on 355-8 but Jamie Porter bowled Ajmal Shahzad and Steve Magoffin in the first over of the day to wrap up their innings for 360.
The hosts reached 77-3 at lunch as Cook edged Magoffin to second slip and Nick Browne and Ravi Bopara fell cheaply.
Westley (86) and Jesse Ryder (51) boosted Essex as they closed on 252-7.
Cook complied with new helmet regulations while batting during the match, after being spoken to by the England and Wales Cricket Board following Essex's victory Gloucestershire last week.


The Women's Tennis Association has signed a new record media rights contract that it says will be worth more than £335m ($525m) over 10 years.

The deal with Perform runs from 2017 to 2026 with plans to produce every singles match, which is around 2,000 fixtures, for the first time.
Under the existing contract with Perform, only around a third of singles matches are broadcast.
WTA chairwoman Stacey Allastar called the new deal "a game-changer".
She added the deal will "give fans more access to the players they want to watch".
The WTA and Perform are forming WTA Media, which will produce all main-draw matches in singles, along with the semi-finals and finals in doubles at every tour event.
Allaster said that the new deal guarantees annual TV rights fees of £21m ($33m) from Perform, which is nearly double the current agreement of (£11m) ($17m) per year that runs 2013-2016.  The deal also includes what Allaster said was "eight figures"' a year in "production investment".
She added: "This comes at a time when we look at the horizon and we will have a changing of the guard of our current top stars, which shows the value and depth of our rising stars."


The Westminster government is signalling that it will cut tax credits in the July budget as part of plan to reduce welfare spending by £12bn.

It appears as though the focus will be on child tax credits. What impact might that have in Northern Ireland?
They are effectively a means-tested benefit paid to people on lower incomes. They are paid to two main groups: unemployed people with children and low paid working people who may or may not have children.
They are perhaps popularly thought of as a state top-up for low paid working people. There are two types of tax credit: Working Tax Credit and Child Tax Credit - it is the latter that seems likely to be cut.
It is paid at a maximum rate of £2,780 per child per year and you are entitled to the full amount until your annual income reaches just over £16,000. Then, there is a formula that sees the amount you get taper away as your income rises. It also depends on the size of your family.
It is a significant number - on the most recent figures there are 140,000 families in Northern Ireland who get child tax credits. About 89,000 are families where someone is working. If we look at working families who only claim the child element of tax credits, it is worth on average £4,000 a year. So we are talking about a significant payment to a large number of people.
The government has promised to cut £12bn from the benefits bill and has not left very much room for manoeuvre. Before the election David Cameron said he would not touch pensioner benefits, which is the largest part of the benefits bill. He also said he would not make any more changes to child benefit.
After that, there are only three areas of spending where you could find savings that are big enough: disability benefits, housing benefits and tax credits.
In June, Newsnight reported that the government was considering cutting child tax credits back to the level they were at in 2004 which, by my calculation, means the maximum amount per child would drop from £2,780 to less than £2,000.
Tax credits are, as the name suggests, a tax matter controlled by HM Revenue and Customs. That means they are not part of devolved welfare powers and Stormont will have no ability to block any changes. However, in the future tax credits will be phased out and replaced by Universal Credit, something Stormont will have power over.


Former Mexican international footballer Omar "El Gato" Ortiz has been arrested for allegedly participating in a kidnapping ring, police have announced.

The goalkeeper is accused of working with a gang operating in Nuevo Leon state responsible for more than 20 abductions, a security spokesman said.
Jorge Domene said 35-year-old Mr Ortiz had admitted helping to select wealthy victims for the group.
Mr Ortiz was suspended from playing in 2010 after failing a steroids test.
Earlier, his relatives said they feared he had been kidnapped as they had not heard from him since Wednesday.
Mr Ortiz, whose nickname means "the cat", was presented to the media along with other suspects on Saturday evening.
Officials in Monterrey accused him of being involved in kidnappings in the second half of 2011, with the group allegedly demanding a ransom of around one million pesos ($72,000; Â£46,000) per victim.
Mr Domene said the victims appeared to have targeted businessmen and "because of that in general they sought large ransoms". He said the group confessed to making "upward of 20m pesos ($1.45m)".
The gang's victims allegedly included the husband of singer Gloria Trevi, who was reportedly quickly freed after his abduction in October.
Mr Domene said Mr Ortiz, who was playing for top division team Rayados de Monterrey when he was suspended in April 2010, had confessed to knowing the gang for more than a year and becoming an accomplice "by signalling the victims who were kidnapped".
"In exchange for that, he received significant payments for his active participation," Mr Domene said. "He has confessed to doing this at least twice, in which he received amounts surpassing 100,000 pesos ($7,260)."
If convicted, Mr Ortiz could face a jail sentence of up to 50 years.


The wife of the gunman who killed 49 people at a gay nightclub in Orlando, Florida, last year has been arrested in San Francisco, US officials say.

Noor Salman is suspected of aiding and abetting her husband Omar Mateen, who was killed in a shootout with police, as well as obstructing justice.
It is expected she will be sent to Florida, where charges were filed.
Fifty-three people were also wounded by Mateen, who vowed allegiance to so-called Islamic State (IS).
Police interviewed Ms Salman last year, believing she may have been aware of her husband's plans.
She told the FBI her husband had become radicalised in the year leading up to the attack.
He made his pledge of allegiance during the actual assault, which lasted three hours.
Ms Salman, who moved to the San Francisco area after the attack on 12 June, is expected to appear in a Californian court on Tuesday.
Confirming the arrest, Attorney General Loretta Lynch told the MSNBC network: "This is a matter that we continue to take very seriously.
"We said from the beginning we were going to look at every aspect of this case, every aspect of this shooter's life, to determine not just why did he take these actions, but who else knew about them, was anyone else involved, is there any other accountability that needs to be had here in this case."
Mateen, 29, was from Fort Pierce, a town about two hours' drive south of Orlando.
His father, Seddique Mateen, said his son had become "very angry" after seeing two men kissing in Miami.
Mateen had been interviewed by FBI officers twice in 2013 following inflammatory comments to colleagues asserting ties to IS but no hard evidence was found.
He appears to have been a regular at the club and contacted men on gay dating apps, raising the possibility that he was conflicted about being gay and had lashed out.


Investigations are under way into dredging for sand on Lough Neagh, with the government admitting it is happening without proper planning approval.

About 1m tonnes a year are removed for use in the construction industry.
Around 150 people are directly employed in an activity that has taken place for decades.
But it is only now that the Department of the Environment (DoE) has admitted there are problems.
Minister Mark H Durkan said: "It appears that a breach of planning control involving the unauthorised working of sand from the lough has been ongoing."
Mr Durkan was answering a series of questions from South Antrim Ulster Unionist MLA, Danny Kinahan.
The minister told him dredging, like mining, needed planning permission, but no records exist for it having been granted to any commercial operators.
But Mr Kinahan said the enterprise must not be prevented.
"It should be allowed. It is the backbone of the construction industry. Certain groups claim it is being dredged illegally which is not quite fair.
"They have been self-regulating for years. It needs monitoring. We need a partnership approach."
The DoE said there is no evidence the ecology is suffering, but it has commissioned studies alongside two continuing investigations into dredging activities.
James Orr of Friends of the Earth said: "The DoE has known something has been happening.
"These sand operators have been on official DoE committees. It is not like they have been hiding. The DoE has capitulated."
A spokesman for the operators described the issue as "a technicality".
He said they were hoping to meet Mr Durkan to resolve the issue soon.
In his response to Mr Kinahan's questions, the minister said the DoE may "regularise or remedy" the breaches that appear to have been occurring.


A rising number of energy customers have switched gas and electricity deals amid widespread calls to benefit from savings that are available.

Regulator Ofgem said there were 3.8 million switches in the first six months of the year.
This was the second six months in a row that the switching total broke three million, and was nearly one million higher than the first half of 2015.
The data follow a major report into competition in the energy market.
According to the Competition and Markets Authority's (CMA's) two-year investigation, two-thirds of UK households were paying "over the odds" for their energy compared with those who have switched to a different tariff.
Ofgem said that customers could save more than £300 by ditching expensive standard variable tariffs for the cheapest deal, often a fixed-term tariff.
The average standard variable tariff of the larger energy suppliers as of 28 July was £1,066. The cheapest tariff available on that date - a one year fixed tariff - was £758, a saving of £308.
"Great deals are there for the taking. There are very competitive offers and many more suppliers to choose from, and that's why more consumers are switching," said Rachel Fletcher, of Ofgem.
To encourage more switching, Ofgem is planning to trial "more effective prompts" on customers' bills to encourage them to compare different tariffs. However, Ofgem said it would not be capping standard variable energy tariffs.
The regulator's response to the CMA report, and the investigation itself, was criticised by some as not being bold enough.
Separately, the Energy Networks Association has launched a new service in England, Scotland and Wales allowing people to contact their network in the case of a power cut by calling 105 or visiting a dedicated website.


Traders on the Ormeau Road in Belfast have complained that their local police station was closed to the public without their knowledge.

Ballynafeigh Police Station was closed on 21 February and people are now asked to attend Musgrave Street or Lisburn Road stations, except in emergency.
The closure came despite extensive work to renovate the building.
Police have said that they released a press statement about the station's closure in January this year.
A spokesperson added that the enquiry offices at the stations had been replaced with "user-friendly and conveniently located community surgeries".
A number of shop owners in the area said they had been robbed in recent weeks and were not happy with the station's closure to the public.
"I think we should have been informed," local pharmacist Gary Jones said.
"The fact that there are these lovely walls and there is nobody behind them seems like a waste of taxpayers' money."


Small firms have raised fresh concerns about the impact of Brexit on employing EU workers.

Research by the Federation of Small Businesses (FSB) found two-thirds of small Scottish firms with EU staff were worried about future skills shortages.
A total of 37% said they would consider reducing operations if Brexit led to extra barriers on hiring EU citizens.
Almost a fifth said they might close their business, while 12% would consider moving their business abroad.
FSB said EU workers helped to plug chronic skills gaps across a range of sectors.
The UK-wide research found 26% of Scottish small employers currently had a member of staff from elsewhere in the EU, with this figure rising to 41% in the Highlands.
By comparison, about a fifth of UK firms employed an EU worker.
Almost 90% of those surveyed said they had recruited their EU staff when they were already living in the UK.
The vast majority of UK respondents (95%) said they had no experience of using the UK's points-based immigration system to recruit non-EU workers.
FSB national chairman Mike Cherry said: "There is real concern among small firms with EU staff that they will lose access to the skills and labour their business needs to survive and grow.
"EU workers are a vital part of our economy, helping to plug chronic skills gaps across a wide range of sectors, and filling jobs in an already tight labour market.
"From packers, to mechanics, to graphic designers, small employers need to be able to hire the right person, for the right job at the right time."
Scottish policy convener Andy Willox said: "Our data shows that our members predominantly recruit non-UK EU citizens because they're the best candidates.
"If our immigration system is set to change, then our skills system needs to do the same."
The survey included responses from 577 Scottish respondents between 31 March and 12 April.


Norwegian firm Marine Harvest has confirmed that it will cut 80 jobs in Scotland, including those at fish farms and offices.

Forty-four posts are to go at its operations across sites in Lochaber, 12 in Mallaig, 11 in Skye and Lochalsh, four in Wester Ross and three in Lewis.
Two jobs are also to be cut in Argyll, two in South Uist and two in Rosyth.
Marine Harvest, the world's largest fish farmer, said the job cuts would make it more efficient and sustainable.
The jobs going in Lochaber include office staff in Fort William and workers at a fish processing plant near the town.
The company employs 658 people at more than 50 sites in Scotland.
It operates four hatcheries, five freshwater loch sites and 48 sea farms.
Its farm operations are situated across Skye, the Western Isles, Lochaber, Wester Ross and Argyll.
Live fish are harvested at a site at Mallaig and processed at Marine Harvest's Blar Mhor processing plant in Fort William. The company has offices at Fort William and Rosyth in Fife.
Thomas MacLennan, chairman of Highland Council's Lochaber area committee, said the lose of jobs would be "a blow" to the Highlands.
He said: "This will undoubtedly have a huge impact on our remote and fragile areas.
"Whilst this is disappointing news, it should hopefully leave Marine Harvest in a stronger position to face the future."


A part-time nursery place for a child under two in Jersey costs parents £2.13 more per hour than in the UK, according to the latest figures.

The average cost of a 25-hours-a-week UK nursery place for a child under two years old is £5,103.
A survey by the Jersey Childcare Trust found the same care in the island costs £7,816.
Last year the States doubled child care tax relief for parents with children aged under three.
At the time, Treasury Minister Senator Philip Ozouf told BBC News: "We are conscious many families have been feeling the pinch."
He added: "This is the biggest targeted improvement in taxation for families with young children the island has ever had."
But Fiona Vacher, the chief executive of the Jersey Childcare Trust, said despite the help from tax relief some parents say nursery costs are like paying for a second mortgage.
She said staff moving to Jersey should get more information about the cost of living in Jersey before they arrive.
She said: "We do see cases, particularly of social workers and nurses, who have come to the island with expectations of how much things will cost, probably basing this on their experience in the UK.
"They see the salary they will be earning here and are really not seeking out the information before they actually come.
"When the reality hits it's not a very good picture."


The Public Prosecution Service is considering a review of the case of a paedophile, who admitted his crimes to police, but was never prosecuted.

Henry Clarke, 75, admitted abusing three different boys at care homes in Northern Ireland.
The retired church pastor, who now lives in Canada, made the admissions in 1985.
A spokesperson for the PPS said the police had not forwarded "significant evidence concerning serious offences".
The Northern Ireland Public Prosecution Service (PPS) has now requested that the chief constable provide this information.
"The PPS is concerned to learn that the police did not forward significant evidence concerning serious offences to the then Department of the Director of Public Prosecutions in 1985," it said in a statement to the BBC.
"Accordingly, a request has been forwarded to the chief constable under section 35(5) of the Justice (Northern Ireland) Act 2002 to now provide this information.
"Given the revelations that have come to light in these cases, the PPS proposes to carry out a formal review of all relevant matters and of any previous prosecutorial decisions relating to Mr Clarke.
"We intend to contact Mr Brown (Henry Clarke's victim Billy Brown) to seek his views on the review and to keep him informed of developments."
Henry Clarke first came to the attention of police in 1982 when an investigation began into systematic abuse at the notorious Kincora boys' home in Belfast.
Some of the teenagers who had been abused at Kincora had come from Bawnmore, where they said they had also been sexually assaulted.
Belfast man Billy Brown, 61, was abused by Clarke at Bawnmore care home in Newtownabbey in 1968.
Mr Brown was just 12 years old and in care when Henry Clarke invited him to his family home, introduced him to his parents and then abused him while he slept.
He said Henry Clarke should be brought to justice no matter how long ago the abuse happened.
"The legal system let me down," he told BBC News NI.
"He should be brought to justice now. He should have faced the courts like everyone else. If I do something wrong I face the courts.
"At the end of the day, why should he not face the courts? I can't understand it. What was the reason they let him go?"
In 1985, Clarke admitted abusing two boys when taken in for questioning by police during a family holiday in Northern Ireland.
In a statement to police, he admitted to sexually touching a child. The indecent assault happened in 1968 - 17 years before his confession.
In spite of his admission, the then Director of Public Prosecutions (DPP) ordered "no prosecution".
Asked why, the current Public Prosecution Service said that the DPP at the time considered the abuse had happened too long ago.
"The directing officer considered that given the time period which had elapsed (17 years) it would be inappropriate to pursue a prosecution," said a PPS spokesperson.
"The prosecutor in this case was following the applicable guidance at the time in the then DPPs' Office."
But leading Barrister Eugene Grant QC said the passage of time did not matter in this case.
"On any reading, the DPP decision not to prosecute here is devoid of any rationale or indeed any legal principle," he said.
"Simply to say a 17-year delay exists without more does not actually hold weight from a legal perspective."
According to evidence given at the Historical Institutional Abuse inquiry, the DPP directed: "It was considered that the passage of time rendered proceedings stale and inappropriate.
Billy Brown said this reason did not make sense because two other child abusers who had sexually assaulted him in the late 60s had been tried and sentenced in the 1980s.
"The other ones, they went to jail, they done their bird," he said. "But he gets away."
After Henry Clarke returned to Canada in 1985, he wrote a letter to police in Belfast, confessing to another case of sexual abuse - this time against a resident from the Conway House children's home who was assaulted at a Boys Brigade camp in Newcastle, County Down.
"I wrote a letter to them and told them that I had missed telling them about this other boy and I felt at that point in time there would be consequences for my admission," he said.
But there were no consequences.
Given the state prosecutor's previous refusal to mount a case against Clarke, this time police did not even tell the DPP about this latest confession; the RUC said there should be "no further action".
A senior police officer wrote: "As the act admitted by Clarke is not punishable in law, there is no necessity to forward papers to the DPP."
But according to the PPS, the sexual touching of a child was, in fact, punishable in law at the time.
Barrister Mr Grant, who examined the papers in the case, said the act carried out on the boy was a crime and questioned the police's reason for not referring the case for prosecution.
"We have in the documentation a statement by a very senior RUC detective, who oversees the investigation, making it quite clear that, in his view, this is not an offence punishable by law," he said.
"That is quite clearly wrong and it does not make any sense, so in my view, the RUC decision not to send this file to the DPP fails."
Questions have also been raised over why the RUC did not alert the authorities in Canada to Henry Clarke's confessions of abuse.
In his letter to the RUC in 1985, he looked for an indication from the police as to whether they intended contacting the Royal Canadian Mounted Police.
A senior policeman from Northern Ireland concluded: "As Clarke has not been convicted of any offence, there is no obligation to notify the RCMP."
The PSNI said it was now reviewing how it shares information with the Canadian police.
Ch Supt George Clarke, head of the PSNI's Public Protection Branch, said: "It is noted that when the decision was taken not to inform RCMP, that was on the basis that Clarke had not been convicted of any offence, which may have been the relevant standard or requirement applicable then."
Since no one in Canada was made aware of Henry Clarke's admissions, he continued to live out his life without anyone in authority knowing about his confessions.
He pastored at four different churches before retiring.
A child protection expert has said he should not have been allowed to get away with the crimes, and that police had enough to pursue a prosecution.
"In this incidence you had an admission, so you didn't have... to worry that the allegation was old, and the evidence may be stale," said Jim Gamble, a former senior officer with the Police Service of Northern Ireland.
Mr Gamble said it was a mistake that Canadian officials were not notified.


Two Australian trainers found guilty of doping horses have had their bans overturned after evidence used to prosecute them was ruled inadmissible.

Melbourne Cup winner Mark Kavanagh and Danny O'Brien appealed after being banned by Racing Victoria for three and four years respectively last year over the use of cobalt chloride.
Four of O'Brien's horses and one trained by Kavanagh failed urine tests.
However, a tribunal said the testing procedure "departed from requirements".
Justice Greg Garde of the Victorian Civil and Administrative Tribunal (VCAT) added: "The legal consequence is that the test results are inadmissible in evidence against the trainers."
O'Brien criticised Racing Victoria following the decision, saying that he and Kavanagh, who won the 2009 Melbourne Cup with Shocking, are "completely innocent".
He added: "Once we understand the ins and outs of [the judgement], we will be reserving all our rights."
Racing Victoria's acting chief executive Giles Thompson said the governing authority were "disappointed" with the outcome and would review the reasons behind VCAT's judgement before deciding on future action.
"It is important to remember that we took action because the horses involved returned cobalt readings that were excessively above the legal threshold that was set to protect both the integrity of the sport and the welfare of the horses," said Thompson.


Kenya has arrested an unspecified number of suspects and recovered a gun potentially linked to the shooting of conservationist Kuki Gallmann, the country's interior minister said.

The 73-year old author of I Dreamed of Africa was injured in an ambush at her conservation park on Sunday.
Ms Gallmann's family said she was in intensive care at a Nairobi hospital.
She endured a seven-hour operation after being airlifted there for treatment.
"We have recovered a gun which is now undergoing ballistic tests to confirm whether it was the gun used to shoot Kuki," Joseph Nkaissery, Kenya's interior minister, told a news conference.
He did not say how many suspects had been detained.
While Mr Nkaissery described the attack as an "isolated" act of banditry, the Laikipia region where it happened has seen a wave of violence in recent weeks.
As well as the Laikipia Nature Conservancy, Ms Gallman ran a luxury safari lodge that was burned down last month by suspected cattle herders.
Herders have been invading private property in the drought-hit area in search of fresh grazing land.
British rancher Tristan Voorspuy, who also ran a safari company, was shot dead in early March while inspecting his lodges in Laikipia.
The region, which covers about 10,000 sq km in Kenya's central highlands, is home to some of the country's largest white landowners.
At least a dozen civilians and police officers have died in the violence there, and tens of thousands of head of cattle are thought to have been driven on to private land.
The BBC's Alastair Leithead tried to approach herders last month to ask about their grievances, but was forced to retreat when they shot at him.
Are Kenya ranch invasions driven by drought or politics?
There is no confirmation of who carried out the attack on Ms Gallmann, who was reportedly shot in the stomach.
Ms Gallmann owns about 360 sq km in Laikipia. Her organisation also runs community, education, arts and sports projects.
Born in Italy, she moved to Kenya in 1972 with her husband and son, who both subsequently died in separate accidents. She later became a Kenyan citizen.
I Dreamed of Africa was turned into a film starring Kim Basinger.


A wealthy Russian businessman who died suddenly near his home in Surrey may have been poisoned, a pre-inquest hearing has been told.

Alexander Perepilichnyy, 44, collapsed and died in the road in Weybridge, Surrey, on the evening of 10 November 2012.
Surrey Police investigated his death, but decided it was not suspicious.
However, new toxicology tests have shown that a rare poison may have been used to kill him.
Mr Perepilichnyy had told colleagues in London he had received death threats, reports BBC world affairs correspondent Richard Galpin.
He had handed over sensitive documents to a businessman in London and to prosecutors in Switzerland, our correspondent adds.
These implicated Russian officials and mafia members in the theft of $240m (Â£147m) from the Russian state through tax fraud.
The full inquest had been due to get under way earlier, but was delayed because of the new toxicology information.
Tests showed a potential marker for a rare poison called Gelsemium elegans. Further tests will be carried out to establish if the poison was in his body.


A Euromillions ticket holder in the Republic of Ireland who has won 66m euros (£50m) in the latest draw has contacted officials to claim the money.

The unidentified player was one of two winners who shared the 132m euros (£100m) jackpot after the draw on Friday, 29 January.
The other winning ticket was sold in France.
The 66m euros prize is the fourth largest Euromillions win in the history of the game in the Republic of Ireland.
A spokesperson for the Irish National Lottery has not revealed where the ticket was sold, but the winner has 90 days to collect the cheque in person from its headquarters in Dublin.


Lewis Hamilton has pulled out of a test aimed at finalising tyres for next season because he was feeling unwell.

Hamilton, who lost the world title to Mercedes team-mate Nico Rosberg in Abu Dhabi on Sunday, was scheduled to drive all day at the Yas Marina circuit.
But after a few laps the Briton felt ill, and Pascal Wehrlein took over.
Mercedes, Red Bull and Ferrari are conducting the test, with modified 2015 cars to simulate the increased downforce of the 2017 new rules.
F1 has introduced a new set of technical regulations aimed at making the cars up to five seconds a lap quicker next year.
The redesigned cars will produce more downforce, while Pirelli has been tasked with making wider tyres on which drivers can push hard throughout a race, unlike the fragile rubber of the past six years.
The test runs until the evening and early lap times were some three seconds slower than this set in qualifying at last weekend's grand prix.
But senior insiders have cautioned against reading too much into individual lap times because the cars are heavy and the engines are old and being run in a detuned state to ensure they last.
