Mexican authorities and scientists are trying to save the world's smallest porpoise by capturing illegal "ghost" fishing nets.

They have managed to remove more than 100 dumped or lost nets left floating in the sea from October to December.
Local fishermen and conservationists helped to trawl 11,814km (7,340 miles) in the Gulf of California, the only area where the vaquita porpoise live.
Its population is estimated to be down to about 60 individuals.
Conservationists say they fear the porpoise will be extinct by 2022.
The main threat to the porpoise are the nets used to illegally catch fish known as the totoaba which is hunted for its swim bladder - fetching tens of thousands of dollars on the black market in China.
The population of the vaquita marina porpoise has dropped despite government measures to prevent illegal fishing with the deployment of navy ships in April 2015.
It went from 200 in 2012 to fewer than 100 in 2014 and now stands at about 60, according to the  International Committee for the Recovery of the Vaquita (CIRVA).
Drones equipped with high-resolution cameras have been used since July to try to spot any illegal movements.
Mexico's environment ministry said on Thursday they had removed 103 nets intended to catch totoaba, shark and other fish between 10 October and 7 December.
But conservationists want to go one step further and attempt to launch a capture programme in spring, says Lorenzo Rojas-Bracho, who chairs CIRVA.
The hope is to make them reproduce in captivity in the gulf, "with the utmost care", he said.
"It would involve locating them, capturing them and putting them in some kind of protective area."
If successful, it would be the first time a vaquita porpoise has been captured alive.
At 1.5m (5ft) long, the porpoise has rarely been seen alive. It is known as the "panda of the sea" because of the dark rings around its eyes.


The US attorney general has said four people have been charged over leaks as the Trump administration launched a crackdown on embarrassing disclosures.

Jeff Sessions said the suspects were accused of divulging classified material or concealed contacts with foreign intelligence officers.
America's top prosecutor said the administration has tripled the number of active leak probes since January.
President Donald Trump has criticised Mr Sessions as "very weak" on leaks.
At Friday's news conference, the attorney general said no government could be effective when its leaders could not talk freely in confidence with foreign leaders.
"I strongly agree with the president and condemn in the strongest terms the staggering number of leaks undermining the ability of our government to protect this country," he told reporters.
He said there had been a "dramatic" increase in recent months of unauthorised disclosures to the media and even foreign adversaries.
The attorney general also said he wanted to review policies on media subpoenas - compelling journalists to reveal sources - to balance the role of the press with protecting national security.
The move is likely to send a chill through US newsrooms that have been breaking almost daily scoops, which have embarrassed the White House.
Jeff Sessions spoke about the Justice Department's efforts to crack down on national security leaks before television cameras and reporters, but his intended audience was almost certainly the man in the Oval Office.
Last week the president lambasted his attorney general for not doing enough to stifle a torrent of leaks over the past six months. On Friday morning Mr Sessions essentially replied: "See? I am doing something!"
What's more, the attorney general served his anti-leak entree with a generous helping of media-bashing, warning that while he respected freedom of the press, he was reviewing when prosecutors could force journalists to reveal their sources - or face criminal sanction.
That's a dish specially crafted for the president's tastes.
Earlier this week, newly minted chief of staff John Kelly reportedly called Mr Sessions and told him that, despite the president's recent swipes, his job was safe. Perhaps Friday's event is part of a larger effort at fence-mending between the commander-in-chief and his former political confidant.
The attorney general will have to deliver results, however. If he can't stop the leaks, it is doubtful the president will be satisfied. And if there's one truth in Washington, it's that the leaks never really stop.

Neil Fox is among the presenters on a new digital radio station launching in London this weekend.

Thames Radio will be a hit music station, playing songs predominantly from the 1980s and 1990s.
It marks the first time Fox will be heard presenting his own radio programme since he exited the Magic breakfast show in September 2014.
The DJ had been accused of sexually abusing fans and colleagues but was later cleared of all charges.
Fox said: "I can't wait to get back on-air in the greatest city on earth.
"Playing London's all-time favourite songs and being able to talk about everything that's happening in the place in which I live and love is going to be an absolute blast."
He added: "This is the station I have wanted to listen to for years, but it simply didn't exist."
Former Fun House presenter Pat Sharp will also host a show on the station, which is owned by Nation Broadcasting.
Sharp, best known as the former presenter of Fun House, said: "For me, being on air once more at a station that will live and breathe London, could actually cap it all."
The station's launch is being overseen by Chris Stevens, who is a former programme director for Smooth Radio.


Midfielder Liam Smith is to return to parent club Newcastle United to recover from an ankle injury suffered during pre-season with Crewe Alexandra.

Smith, 20, only joined League Two Alex on loan earlier in July until January 2017 and was hurt in a friendly against Bolton Wanderers on Friday.
"The good thing is he hasn't got any ligament damage or fracture," boss Steve Davis told BBC Radio Stoke.
"He's got bruising to the bone and it's difficult to know how long it'll take."
Davis, though, is hopeful Smith will be back in a matter of weeks.
"They've said do nothing for 10 days and reassess to see if he can put any load on it so he'll go back to Newcastle for a short spell while he can't do anything," Davis, 51, said.
"You could be looking at three weeks or it could be more or less than that.
"The good thing about him going back is that they have got things there medically that we haven't got here and can get the bruising down quicker."
With finances tight at Gresty Road, the loss of Smith - one of only three new signings this summer - has left Davis with a potential hole to fill.
"If there is someone out there who fits the bill I can put it to the board," Davis said. "We're close to the budget and we're still looking at three or four players to renew contracts.
"But there's a hole there and we're going to be light in that position - we need to do something now rather than leave it until January."


Autumn 2010 and in the bar of the Radisson Edwardian hotel in Manchester the then general secretary of Unite union, Derek Simpson, and the union's political officer - and former Gordon Brown aide - Charlie Whelan were enjoying a drink and were in excellent spirits.

Just across the road in the city's conference centre it had been confirmed that very afternoon that Ed Miliband had pipped his brother for the Labour leadership.
The giant union had encouraged its members to back the younger Miliband and they were celebrating.
But after a messy row with Unite over the selection of a Labour candidate in Falkirk in 2013, the rules for electing Ed Miliband's successor were changed by the very leader who had most benefitted from them.
Previously, the unions commanded about a third of the vote in Labour's "electoral college" - with ordinary members' votes also counting for a third, and MPs and MEPs the remaining third.
Fast forward to 2015 and the special status of MPs in leadership votes has all but gone.
Hopefuls now require the support of 15% of their parliamentary colleagues to take part but when the ballot is held every MP, like every party member - and those who also sign up as registered supporters at a lower rate than the full membership fee - has just one vote each.
The unions' role has changed just as dramatically.
They no longer have a third of the vote guaranteed.
And while in the past any member who paid the political levy had the opportunity automatically to vote for the Labour leader, each member now has to make a positive decision politically and financially to participate in the ballot.
Each trade union member who isn't already in the Labour Party must agree to sign up as an "affiliated supporter" at a cost of Â£3.
To encourage this, unions have set up call centres and printed and distributed the appropriate forms.
The GMB union is using a picture of Lord Mandelson on their leaflet, in the role of a New Labour pantomime villain - suggesting he and his chums will have too much influence unless rank and file union members sign up for a vote.
But how influential will the unions be in determining the outcome?
The GMB general secretary Paul Kenny says his union has signed up just 10,000 affiliated supporters so far.
He has a target of signing up 60,000 - that's still only one in 10 of the membership.
The larger Unite union won't release figures but sources there say they have a similar tally to the GMB.
Their call centres tell members about the new process but officials believe most people will join up after face-to-face approaches by shop stewards.
They say outside London, where the Labour vote went up at the general election, it's been more of a challenge to encourage participation.
Overall, the unions have a target of signing up 200-250,000 affiliated supporters.
That would give them rough parity in the leadership contest with fully paid-up members of the Labour Party and registered supporters but it wouldn't allow them to dominate the process.
But this target may be ambitious, as only 250,000 union members took part last time when they didn't have to go through the hoop of consenting to cough up cash for the privilege.
But it's also misleading to assume that these new affiliated supporters would necessarily follow the lead of their union bosses in any case.
First of all, ballot papers will be sent out by the Electoral Reform Society not the trade unions.
Union leaders won't be able to send out literature for just one candidate along with the ballot paper.
The GMB and Unite were both accused of doing this in 2010 for Ed Miliband. GMB sources concede there was some Ed literature "in the overall wrapping".
Second, even under the old system recommendations weren't always followed.
So, for example, the GMB hierarchy 20 years ago urged members not to elect Tony Blair as leader - and were firmly ignored.
And far more recently - last year in Scotland - the Unite leadership urged a vote for left-wing MSP Neil Findlay. The members preferred the better-known Blairite MP Jim Murphy.
And the most Blairite of the Labour leadership candidates, Liz Kendall, approves of the new system which she believes diminishes the role of union general secretaries.
It's not clear how many unions will make any recommendations to their members this time. Some will hold off until after a hustings, to be organised by TULO - the umbrella body for unions that have a financial link with Labour towards the end of next month.
But even in the unlikely event that all of them backed, say, Andy Burnham then that's no guarantee of success.


Jose Mourinho was back doing what he does best at Wembley on Sunday... lifting silverware, as Manchester United beat Southampton in the EFL Cup final.

Mourinho claimed the season's first major trophy and ensured success just months after his appointment despite a largely disappointing United performance which was rescued by two-goal inspiration Zlatan Ibrahimovic.
The 35-year-old Swede and Mourinho - instrumental in bringing him to Old Trafford after the pair forged a bond at Inter Milan - are now the two central figures leading Manchester United forward.
Mourinho was brought into Old Trafford as the manager who is as close to a guarantee of success and trophies as it gets after a silverware-lined career at Porto, Chelsea, Inter Milan and Real Madrid.
Old Trafford's joyless existence under Louis van Gaal demanded change and Mourinho was the identikit of the sort of manager required at 'The Theatre of Dreams' - a personality who would relish its history and surroundings rather than shrink from it.
Mourinho was also available and had a third Premier League triumph on his CV only 12 months earlier at Chelsea. It meant United were prepared to set to one side his track record for short-term stays in exchange for a quick fix.
United were thoroughly unconvincing at Wembley but Mourinho and his teams invariably find a way to win trophies. And so it proved as Ibrahimovic headed home an 87th-minute winner.
Mourinho's move to bring the Swede in on a free transfer from Paris St-Germain was strategic and wise.
He is a personality of equal stature and confidence, had a point to prove having never played in England and could provide the sort of charisma that had echoes of the great Eric Cantona.
How United needed Ibrahimovic because for long periods they were desperately average, outplayed by Southampton and had their hand held by Lady Luck throughout.
If United are to build on this first trophy of the Mourinho era, then Ibrahimovic's continued presence is essential because the EFL Cup final win is only the first building block in an Old Trafford edifice that requires considerable renovation after the dismal post-Sir Alex Ferguson years of David Moyes and Van Gaal.
Mourinho, however, is safe hands when it comes to winning trophies and United remain in serious contention for two more in the Europa League and FA Cup - this is a good start but the success-hungry Portuguese will want more.
United's lean years simply could not continue with Pep Guardiola arriving at Manchester City, Jurgen Klopp settling at Liverpool and Antonio Conte conducting a brilliant transformation of Mourinho's former charges Chelsea.
Mourinho won the Premier League twice, as well as the FA Cup and two League Cups, in his first spell at Chelsea. He won 124 games out of 185 in that period, a win ratio of 67%.
He won 80 out of 136 in his second stint at Stamford Bridge (59% win ratio) - winning the title again and the League Cup - while he has won 28 out of 43 at United at an impressive 65%.
The statistics add up to exactly what is required at Old Trafford.
He will chase the Champions League prize either through the Premier League or the Europa League because this is vital to his future plans.
In the meantime, Ibrahimovic once again proved himself indispensable. He was the difference here. He made the decisive contribution to clinch a game for Manchester United they did not deserve to win.
He is head and shoulders - quite literally - above every other player at United. He has scored 26 goals this season with Juan Mata next with nine. He has had 143 shots compared to Paul Pogba's 117 while he has had 65 shots on target compared to Pogba's 39.
Zlatan tops every significant attacking table.
Manchester United are a long way from their former greatness - but this EFL Cup final proved conclusively that if they are going to get anywhere near that status again Ibrahimovic is the man who is integral to Mourinho's plans, even at 35.
Manchester United winning a Wembley final equates to tangible success - but successful seasons are measured in different currency in the modern era and Mourinho will need more than this EFL Cup triumph against unlucky Southampton to achieve full satisfaction.
Van Gaal, who led United to FA Cup success in May, was on his way out of Old Trafford almost as soon as he placed the trophy on the same table Mourinho sat at on Sunday.
If winning the FA Cup was not enough to satisfy United's desires for success under Van Gaal then it would take a re-drawing of the boundaries to now paint the EFL Cup as fulfilling their ambitions.
There is a key difference in mood here - whereas Van Gaal's Wembley win felt like the end of a story, this victory, for all its good fortune, had the sense of new start.
Mourinho must now make this season feel like the full package of progress by leading Manchester United back into the Champions League, which is surely the minimum requirement after the world record transfer expenditure on £89m Paul Pogba and the Ibrahimovic coup - the latter being a player who would regard the Champions League as his natural stage.
And United still have an excellent chance of ensuring this season can be viewed as a success as they stand among the favourites for the Europa League and the prize in the Champions League it now offers.
Mourinho has already painted the last-16 meeting with Russians FC Rostov as a tough tie but he also has the chance to reach the top four in the Premier League, with United only two points behind Arsenal in fourth place.
United have a potentially hazardous FA Cup quarter-final tie at Premier League leaders Chelsea to negotiate, but this is a season still moving on three fronts after securing that first major trophy.
The new reality is, though, that while the EFL Cup provides a trophy and satisfaction, United's season will only be a success if they conclude it back in Europe's elite competition.
Wayne Rooney lifted the EFL Cup and demonstrated he is the consummate team player with his wild celebrations of Ibrahimovic's winner - but this was still a player on the outside looking in.
The 31-year-old, who this week confirmed he was staying at United despite speculation linking him with a move to China, was denied a piece of the action by the match-winning contribution of the elder statesman who has usurped him as the team's spiritual leader.
Rooney was stripped and ready for action. With the words of Mourinho ringing in his ears and Rui Faria showing him the diagrams United hoped would lead to a defining contribution, Ibrahimovic struck.
The Manchester United and England captain was sent back to the bench with no chance to add to his 250 goals for the club as Marouane Fellaini was called in for a late lockdown. It was a symbolic moment.
United's captain for the day Chris Smalling let the club's all-time record goalscorer Rooney lift the trophy and it is to his credit that there was no sense of personal denial or disappointment that he was left out then denied even the smallest part.
Rooney was delighted for his team-mates, which is a mark of his approach.
Despite this, there was no escaping the belief that the guard has changed at Old Trafford. Rooney is no longer the main man - he is now well down the ranks and this was simply another piece of evidence of his declining influence and the credits rolling on a magnificent career at Manchester United.
Mourinho's downbeat demeanour was a talking point throughout the EFL Cup final as he cut an unsmiling, subdued figure who barely showed any emotion even when Manchester United scored.
Mourinho insisted afterwards he was delighted: "I am very happy. It is important for the fans, for the club and for the players. I always try to put myself in the secondary position but the reality is it is also important for me."
United's performance was not designed to lighten Mourinho's mood until the moment of victory and it is likely his behaviour was shaped by concerns about how Southampton dominated his side for long periods and troubled his defence - normally his tactical strong point - throughout.
Victory will, however, lighten his mood, bolster his already high standing with United's fans and release any personal pressure he may have been feeling.


In the controversial history of the US military detention centre at Guantanamo Bay, Cuba, this week marks a small but significant landmark.

A Yemeni national, Mahmoud Mujahid, held there without trial since 2002, is the first to be re-evaluated for transfer and eventual release by a new US government panel set up by presidential order in an effort to hasten the camp's closure.
Previously classed as "too dangerous to release," the alleged former bodyguard to Osama bin Laden has now been transferred from indefinite detention to a list of those "approved for transfer," where he joins 55 other Yemenis.
It took six US government agencies and departments to all sign off on his transfer, namely: Defence, State Department, Homeland Security, Justice, Director of National Intelligence office and the Joint Chiefs of Staff.
But in practice, there is no indication that Mr Mujahid is about to go home soon.
Of all the countries the US is looking to repatriate Guantanamo Bay's remaining 155 inmates to, Yemen presents it with the greatest problems.
Even before the turmoil of the Arab Spring erupted onto its streets in 2011, Yemen was plagued with poverty, insecurity and terrorism.
Today it is home to al-Qaeda in the Arabian Peninsula (AQAP), it is riven by power struggles and tribal rivalries, and after a number of earlier failed experiments it has no effective mechanism for rehabilitating former detainees from Guantanamo Bay into mainstream society.
Some of the most skilled and dangerous senior members of AQAP now at large in Yemen are former detainees who renounced violence in exchange for their release.
Such was the US government's distrust of Yemen's ability to handle returning prisoners and stop them joining al-Qaeda or other militant movements that in 2010 it imposed a moratorium on all repatriations to Yemen.
But with the Obama administration's renewed push to deliver on the president's original pledge to close the camp, that moratorium was lifted in May 2013, to be replaced by a case-by-case review.
Yemenis make up the majority of Guantanamo Bay's remaining inmates, with estimates of their number varying from 80 to 88. Others include 18 Afghans, 9 Saudis and 6 Pakistanis, as well as several men from North Africa.
The London-based campaign group Reprieve has been pushing for the camp's closure and says the US government could, if it had the political will, work faster to repatriate its inmates.


Andy Mangan scored his first goals since re-signing for Tranmere with a brace in their victory over Torquay at Prenton Park.

The hosts started the brightest and striker Mangan opened the scoring on 12 minutes as he found the back of the net with a great curling effort from the left side of the penalty area.
Four minutes later, the former Bolton youth player sent home another chance before the referee's assistant chalked it out for offside, but he made no mistake as he fired through Torquay goalkeeper Brendan Moore's legs to double his tally at the start of the second half.
The Gulls pulled one back just after the hour as Lee Vaughan miscued a pass back to Scott Davies and Dan Sparkes took advantage and reduced the deficit, but Rovers held on for maximum points which saw them move up a spot to fourth.

Dave Chisnall and Michael Smith were eliminated from the 2016 Premier League following defeats in Cardiff.

Smith lost 7-5 to 16-time world champion Phil Taylor, while Chisnall was beaten 7-5 by Peter Wright.
Those results meant Robert Thornton, the only other man who could have exited the competition on Thursday, was already assured of a top-eight place before he lost 7-4 to Adrian Lewis.
Taylor's win put him a point clear at the top of the table.
Michael van Gerwen drew 6-6 with fellow Dutchman Raymond van Barneveld, a result which extended the world number one's winless sequence in the Premier League to three matches.
Meanwhile, defending champion Gary Anderson's run of six successive wins was ended by a 6-6 draw with James Wade.
Points gained in the first nine weeks of the competition will be carried forward and the remaining eight players will face each other once during seven further rounds of fixtures.
The top four in the table after 16 rounds will qualify for the play-offs in London on Thursday, 19 May.
Premier League - round nine results
James Wade 6-6 Gary Anderson
Michael Smith 5-7 Phil Taylor
Dave Chisnall 5-7 Peter Wright
Robert Thornton 4-7 Adrian Lewis
Raymond van Barneveld 6-6 Michael van Gerwen


It's a big day for fans of eclipses, cruise ships, Bonnie Tyler and members of the Jonas Brothers.

News has reached us that Bonnie Tyler is going to perform her 1983 hit Total Eclipse of the Heart.
On a cruise ship.
During an eclipse.
With one of the Jonas brothers.
The eclipse will take place on 21 August and last for about two minutes and 40 seconds.
Tyler will perform (a presumably shorter version of) the song while the eclipse is taking place.
The ship, the Royal Caribbean's Total Eclipse Cruise, will be positioned in the path of totality for the critical moment.
Let's hope the sky will be clearer than it has been in the UK this month.
Surely Bonnie Tyler was a natural choice for this once-in-a-lifetime moment?
"Bonnie Tyler was a natural choice for this once-in-a-lifetime moment," said the president and CEO of Royal Caribbean International, Michael Bayley.
"It's going to be so exciting, it doesn't happen very often, does it?" observed Bonnie when she spoke to Time magazine.
The singer will perform alongside Cake By The Ocean hitmakers DNCE - a band led by Joe Jonas - on the cruise, which departs from Orlando for the Caribbean on Sunday.
You'll naturally be worried about Bonnie getting seasick, we imagine, but there's no need to panic.
She said: "I have a ship of my own. I go with the flow, darling. I'm not worried about things like that."

Two women arrested after a toddler was found alone in a street in Grangemouth have been released by prosecutors.

The women, aged 33 and 54, were charged under the Children and Young Persons Act after the girl was found on the corner of Abbotsford Drive on Sunday.
They had been due to appear at Falkirk Sheriff Court, but were released after the Procurator Fiscal decided there was insufficient evidence.
The case has been referred to the Children's Reporter.
A Crown Office spokesman said: "After full and careful consideration of the facts and circumstances of the report, the Procurator Fiscal decided that there was insufficient evidence of criminality to take proceedings against them."


The UK has had its credit rating outlook cut to "negative" by the ratings agency Moody's after the country voted to leave the EU.

Moody's said the result would herald "a prolonged period of uncertainty".
Meanwhile, PM David Cameron is under pressure to speed up "divorce" talks with the EU after Brussels said exit negotiations should start immediately.
EU head Jean-Claude Juncker said it was "not an amicable divorce", but it was "not a deep love affair anyway".
Moody's said the referendum result would have "negative implications for the country's medium-term growth outlook", and it lowered the UK's long-term issuer and debt ratings to "negative" from "stable".
It added: "In Moody's view, the negative effect from lower economic growth will outweigh the fiscal savings from the UK no longer having to contribute to the EU budget."
It also said the UK had one of the largest budget deficits among advanced economies.
Colin Ellis, chief credit officer at Moody's, told BBC Radio 4's Today programme the UK's credit rating could have an impact on UK households in the long term.
"The government borrowing rate is normally the benchmark - it is the rate at which other interest rates in the economy are set," he said.
"A lower rating would typically correspond to higher borrowing costs, and that would be felt not just by the government but by businesses and households in the longer term."
The financial assessment came after the UK voted to leave the EU in historic referendum on Thursday.
Credit rating agencies, in essence, rate a country on the strength of its economy.
More specifically, they score governments (or large companies) on how likely they are to pay back their debt.
The higher a credit rating, the cheaper it is for a country to borrow money in the international markets.
So, in theory, when a government wants to borrow money, a high credit rating means a lower interest rate (and vice versa).
There are three main ratings agencies - Moody's, S&P and Fitch. The last two have yet to issue a comment on the UK post-referendum.
Credit rating agencies also give each country a specific credit rating score. In the case of Moody's and the UK, it currently scores the UK at "Aa1".
This is the second highest rating in Moody's scale, and stands for "high grade", below "AAA" which is "prime".
By changing its outlook to "negative", Moody's has warned that the UK's "Aa1" rating may be at risk of being lowered.
Mr Cameron had urged the country to vote Remain in Thursday's referendum but was defeated by 52% to 48%.
On Friday morning, he stood outside 10 Downing Street alongside his wife Samantha to announce he would remain in place for the short term and then hand over to a new prime minister by the Conservative conference in October.
He said he would attempt to "steady the ship" over the coming weeks and months.
However, the PM said it would be for a new prime minister to carry out negotiations with the EU and invoke Article 50 of the Lisbon Treaty, the formal procedure that will take Britain out of the EU, a process that will take a minimum of two years.
But in an interview with German TV, European Commission President Jean-Claude Juncker said: "Britons decided yesterday that they want to leave the European Union, so it doesn't make any sense to wait until October to try to negotiate the terms of their departure - I would like to get started immediately."
He said the EU would pursue a "reasonable approach" in negotiating the separation.
Earlier, Mr Cameron was given assurances from US President Barack Obama that the UK would remain "an indispensable partner".
In a telephone call, the US leader told Mr Cameron that he regretted the PM's decision to step aside, saying he was "a trusted partner and friend".
A White House spokesman later said Mr Obama "stands by what he said" about the UK going to "the back of the queue" when it comes to trade deals with the US.
He gave the warning while on a visit to the UK during the referendum campaign.
The result of the referendum - which saw more than 30 million people turn out to vote - saw British bank shares lose nearly a third of their value before rallying on Friday afternoon.
Retailers and the AA motoring organisation warned that petrol prices were likely to rise by 2p-3p a litre because of the pound's fall against the dollar.
Boris Johnson, the leading voice in the Leave campaign is favourite to be the next Tory leader and prime minister, although he has yet to announce his candidacy, with Home Secretary Theresa May also seen as being in the running.
Britain's vote to quit the EU has also prompted fresh calls for Labour leader Jeremy Corbyn to resign, amid claims he did not do enough to convince Labour supporters to vote for Remain.
The referendum result could also trigger a second independence referendum in Scotland, which wants to stay in the EU.
First Minister Nicola Sturgeon said it was "democratically unacceptable" to force Scotland, which voted strongly to remain in the EU, out of the bloc against its will.
A meeting of 27 EU leaders has been scheduled for Wednesday to discuss Britain's exit - but Mr Cameron is not invited.


Rangers boss Ally McCoist has finally signed off on a pay cut of around 50%,

McCoist's £825,000 salary was made public in the club's annual accounts but as part of cost-cutting measures he had been willing to have it halved.
Despite the club losing money on a monthly basis, it has taken until now for that to be implemented.
Rangers have also employed Philip Nash to oversee the financial overhaul at Ibrox.
Chief executive Graham Wallace has acknowledged it is necessary at the club and has brought in Nash as a consultant.
He has previously worked for Arsenal and Liverpool and is charged with helping Wallace and the finance director Brian Stockbridge sort out the Scottish League One club's finances.
A spokesman for the Rangers board said: "Mr Nash is a consultant and will be called on from time to time by Graham Wallace as he works on his 120-day restructuring project.
"Mr Wallace will call on the best strategic minds in the sporting and business world to put Rangers Football Club back to where they belong."
The share price of the Rangers International Football Club plc fell to a new low of 28.5p on Friday, less than a third of the 90p price at the launch of the share issue just over a year ago.


The parents of Nicola Payne have made their children promise to bury her alongside them if the truth about her disappearance is ever discovered.

Miss Payne, from Coventry, vanished as she crossed wasteland towards her parents' house in 1991.
On Monday, two men, Nigel Barwell and his brother-in-law, Thomas O'Reilly, both 51, were found not guilty of the 18-year-old's murder.
Her family say they are more determined than ever to find out what happened.
Nicola's parents, John and Marilyn Payne, both aged 70, said they will be talking to the senior detective in the case about possible future developments and that West Midlands Police have assured them the case will not be closed.
Updates on this story and others from Coventry and Warwickshire
Police advised them they would be entitled to sue the force over mistakes made in the investigation, but they said have no intention to do so.
"We are just focussed on finding the truth," they said.
"I just want the three Cs - conviction, closure and comfort," Mrs Payne said.
The couple said they had made their eldest son, Nigel Payne, promise that if they die before the truth about Nicola is known, then she will be buried along side them.
The murder trial at Birmingham Crown Court had heard lawyers on behalf of Mr Barwell describe the handling of exhibits at a police station in the early 1990s as "shambolic".
Mark Dennis QC said the handling of a tent exhibited in the case made forensic examination of it "a worthless exercise".
After the not guilty verdicts were returned, Det Supt Mark Payne, of West Midlands Police, said he had offered his apologies to Miss Payne's parents for any mistakes that may have happened over the intervening 24-year period.
"We will continue to revisit the evidence available and explore any opportunity to bring any offenders to justice," he said.


Parents feel unable to make children study by blocking internet access, as homework often requires online research, a survey suggests.

Some 63%, of 2,000 UK parents polled said confiscating smartphones and tablets was futile.
But 70% feared social media could distract children from their work.
The survey, for an internet blocking service, found 56% felt using parental web filters could damage their relationship with their children.
Many parents said they wanted their children to develop the self-discipline to control their own internet use.
Parents of secondary pupils aged 11 to 16 were questioned earlier this month.
"What am I supposed to do? Stop her when she says it's essential for her homework. But when she's meant to be working, she's actually on social media on the computer," said the mother of 15-year-old Elly, from Worcestershire.
"He took two hours to do his homework - 20 minutes doing it, the rest of the time mucking about on the web. Turn off the internet and he has a tantrum," said another parent.
The parent of a 12-year-old said an attempt to block the internet had resulted in rebellion: "She just sat there and didn't do her homework for the whole time the internet was blocked."
BBC News School Reporters Olivia and Claudia, both 14 and from the Charles Dickens School in Broadstairs, Kent, admitted being easily sidetracked online, particularly by Facebook.
"I don't think it is practical to turn the internet off because I do use it for most of my homework. I think a better solution would be to temporarily block Facebook," said Olivia.
She said her parents tried to stop her spending "unreasonable amounts of time" on the internet but trusted her enough not to block it.
Claudia said her parents sometimes confiscated electronic devices or put a timer on the household internet connection.
"I personally believe it is better have self-discipline because it shows that you are mature and focused," she added.
Siobhan Freegard, co-founder of the parenting website Netmums, said parental internet filters could be blunt instruments, signalling "a total lack of trust and understanding" between parents and children.
Dialogue was better, she suggested, along the lines of: "Come on, let's get this homework done," but she admitted it could be difficult.
"I have a boy who is just not interested in academia. He can be distracted just as easily by a spider on the wall as by social media.
"There have always been distractions. I can remember being told off for reading Jackie magazine inside my textbooks.
"There was a feeling that only children from bad families did their homework with the TV on.
"My parents used to tell me, 'You can't concentrate with music on in your bedroom.'"
Some parents said they preferred their children to control their own internet use.
Elly and her parents now use software that allows Elly to set her own homework targets, block the internet for the time she needs to achieve these targets and award herself success ratings when she completes her homework in time.
"She's in full control. She loves it. She writes down her goals, puts in the social media sites she wants to block and the amount of time," said Elly's mother.
Will Little, of Stop Procrastinating, the web blocking service which commissioned the survey, said many parents wanted to encourage their children "to block the internet for their own benefit rather than because their parents are telling them to".


The Godfather of Punk Iggy Pop is to host a weekly show on BBC 6 Music after a stint on the station last year.

From Friday 10 April, the veteran US performer will host a weekly show which airs from 1900 to 2100 BST.
Iggy Pop said: "Having sat in for Jarvis Cocker last year on BBC Radio 6 Music, I found myself realising how good it was for me. I hope it was good for somebody else too."
Tom Ravenscroft's 6 Music show is also moving to 21:00-00:00 BST.
It had previously run from 19:00 to 22:00. The changes to the schedule mean the station will no longer be broadcasting 6 Mix, a weekly show featuring a range of resident and guest DJs delivering a two-hour set.
Ravenscroft said: "It's great to have the creative freedom to explore music even more deeply in my new regular slot on 6 Music."
Iggy Pop first presented two shows on the network in December 2013 and returned last year to front a weekly Sunday afternoon show, taking over Jarvis Cocker's Sunday Service slot.
He also delivered the fourth John Peel Lecture with a speech on the subject of Free Music in a Capitalist Society.
He said the new show will be "what we call in the USA the 'happy hour'.
"It's kind of an edgy point right at the end of the designated work week, and I'll try to play quite a bit of music that's new and stimulating mixed with very old classics from the blues and jazz masters of the 1920s through 50s that are a little more moody. I'm gonna think of myself as a kind of atmospheric bartender. I'll try to do my very best."
BBC 6 Music's head of programmes Paul Rodgers said that in the latest round of official radio listening figures, "Iggy had driven his Sunday afternoon show to a slot record of over 300k listeners".
He added: "To welcome him back in a permanent slot on the network is a dream come true for me and our listeners, and we all look forward to hearing his eclectic musical selections each Friday evening."


It's the announcement everyone has been waiting a year for.

International ballroom champion Shirley Ballas has been named as the new head judge on Strictly Come Dancing.
Nicknamed the Queen of Latin, the 56-year-old will replace Len Goodman when the BBC show returns this autumn.
Highly regarded in the world of ballroom, she has numerous titles to her name and is also the mother to Dancing with the Stars professional champion Mark Ballas.
Strictly professional Anton Du Beke and former judge Arlene Phillips were among the favourites to take on the head judge role.
Although not widely known to UK audiences, Ballas has been frequently seen on Dancing with the Stars, the US version of Strictly - on which Mark appeared for 10 years - giving masterclasses and commentary.
"I am so excited and over the moon to have been given this wonderful opportunity," she said.
"I can't wait to get in to the ballroom and be part of the incredible and respected judging panel. Strictly is so loved by the British public, I have always been a massive fan.  I just can't wait!"

Did you know there are 40 grass courts at Wimbledon and that they grow the grass every year?

10 July 2017 Last updated at 15:42 BST
There is a team of over 30 people who mow, mop (yes, mop!) and paint the lines on the courts every single day during the tournament.
That's a lot of green fingers - 300 to be exact!
Ayshah went to meet Grant, who's in charge of the grass, to find out some secretsâ€¦


George Michael has been given an eight-week sentence for crashing his car while under the influence of cannabis.

He was also fined Â£1,250 at Highbury Corner Magistrates Court in London and given a five-year driving ban.
The 47-year-old singer was arrested in July in Hampstead, north London after driving his Range Rover into a branch of photographic store Snappy Snaps.
Last month he pleaded guilty to driving under the influence of drugs and possessing cannabis.
The singer was told then that his offences were "a serious matter" and that he could face imprisonment.
Michael is expected to serve four weeks in prison.
The pop star was greeted by a horde of photographers as he arrived at court earlier.
In 2007 he admitted another charge of driving while unfit through use of drugs at Brent Magistrates Court in London.
Michael was found slumped at the wheel of his car in the early hours of 4 July having crashed it into the store frontage.
He was arrested and taken to Hampstead police station, where he was found to be carrying cannabis cigarettes.
Michael shot to fame as half of pop duo Wham! before embarking on a successful career as a solo artist.
GEORGE MICHAEL'S LEGAL HISTORY
George Michael's brushes with the legal system
The singer - whose real name is Georgios Panayiotou - has made no secret of his long-time use of cannabis.
The BBC's Lizo Mzimba was in court and said Michael had "gasped" when his sentence was passed down.
Earlier his barrister said the singer was trying to get his life back on track and had started writing new material.
"For the first time in many years he has started writing again," said Mukul Chawla QC. "His creativity, so long hampered by his drug dependence, is re-emerging."
District Judge John Perkins told the singer he had taken a "dangerous and unpredictable mix" of prescription drugs and cannabis.
"I accept entirely that you have shown remorse for the offence, that you are ashamed of it, that you admitted it," he added.
"With regret," however, he said he had no alternative in this case but to give him a custodial sentence.
"It does not appear that you took proper steps to deal with what is clearly an addiction to cannabis," he told the singer.


The team behind The Grand Tour will use Twitter to gauge its popularity with fans, the show's producer has said.

Speaking to BBC Radio 4's Today programme, Andy Wilman also confirmed they will not be told what the viewing figures are.
He said: "We'll never know the number, because, even to us, Amazon won't tell us what the viewing figures are."
Asked how they will know if viewers like the show, Wilman replied: "We'll get it from Twitter I would imagine."
He added that TV fans "are all there [on social media] with their thumbs banging away".
The Grand Tour, which launches on Amazon Prime on Friday, stars Jeremy Clarkson, James May and Richard Hammond and will be the trio's first show since leaving BBC Two's Top Gear last year.
Wilman said it was a "blessing" that the creative team behind the show would not be told the overnight viewing figures.
"You can just make something and never have to be sort of judged by looking for overnights and so on.
"That is quite a liberating thing, that we will just make our show... it's just going to exist out there."
Do overnight TV ratings matter?
"Over time hopefully millions will watch it, but we've said goodbye to that big figure coming in on a Monday morning," he added, referring to the overnight ratings the Top Gear team used to receive the morning after its Sunday night broadcast.
Some press reports have suggested that Amazon have given The Grand Tour a budget of £4m per episode.
But, Wilman said: "That figure is nonsense. It was reported in the papers and it's stuck there for good now. It's not true. It's lower than that. I'm not going to tell you the figure but it's a good whack."
Asked whether the budget was higher than the £1m per episode the BBC reportedly spent on Top Gear, Wilman replied: "It's more than that. Somewhere between £1m and £4m."
One episode of The Grand Tour will be released per week - unlike many programmes broadcast on streaming platforms which release all their episodes at once for viewers to watch when they wish.
Speaking about the one-per-week release, Wilman said: "It's a good thing because if it was Breaking Bad or something like that, you've got a plot and you go 'Oh I've got to see the next one'.
"There's no plot in what we do. It's three overgrown idiots doing stuff. There's nothing to make you go 'I've got to watch the next one', so I'm happy there's a gap between each one."
He added that Amazon had had "no editorial input" in the making of The Grand Tour.
"They just left us alone," he said. "The BBC left us alone as well, in the main, editorially. Amazon have done the very same thing.
"We make a show, we send it over, thankfully they're making nice noises when they see it."

Have you been feeling hot and bothered lately?

21 June 2017 Last updated at 13:31 BST
The UK has experienced a heatwave recently and today has been the hottest June day for more than forty years.
But what's been causing it and how long will it last?
BBC Weather reporter Simon King has all you need to know.


Children's author Helen Bailey may have been alive when she was dropped into a cesspit at her home, a court has heard.

The 51-year-old was found in the grounds of her home in Royston, Hertfordshire, in July. She had been missing for three months.
Her partner, Ian Stewart, 56, has denied murdering her.
Pathologist Dr Nathaniel Cary told St Albans Crown Court it was "possible that she was put down the well in an unconscious state and then drowned".
Ms Bailey's body was discovered in a cesspit beneath the garage submerged in liquid, including human excrement, the court heard.
More on this and other news from Hertfordshire
The body of her dachshund Boris was found next to her, together with a dog's toy.
The Northumberland-born author of the Electra Brown series for teenagers, had last been seen alive on 11 April.
The cause of Ms Bailey's death was officially listed as "undetermined", Dr Cary said.
Post-mortem tests showed no signs of injury. There were no broken bones, no evidence of bruising or brain bleed, he told the jury.
Analysis of her hair found traces of the sedative Zopiclone, which had been prescribed to Mr Stewart, had been in her system for several months and was present at the time of her death.
Toxicologist Dr Mark Piper said side effects of the drug could include short term memory loss perhaps leading someone to think "their mind was playing tricks".
The jury was told earlier that in the weeks before her death the writer had emailed friends describing how she felt confused and mentally impaired.
Pathologist Dr Cary said if she had been sedated, Ms Bailey could have been killed without visual injuries by more "subtle" means.
"Subtle modes of death include smothering and compression of the neck by means including an arm lock, using the crook of the elbow... also called a sleeper hold, it is used in certain martial arts to reduce consciousness."
Cross-examined by defence counsel Simon Russell Flint QC, Dr Cary said he was speculating, but added: "On the basis of the case as a whole, it is my opinion that not only was she concealed by a third party but it seems likely she died at the hands of the third party by some means."
He added: "It is possible that she was put down the well in an unconscious state and then drowned... but impossible to confirm that given the amount of time the body was in water.
"I cannot discount it, it is one of a range of possibilities."
The vet who carried out post-mortem tests on Ms Bailey's dog had been unable to ascertain the cause of death.
No Zopiclone was found in its system and in a statement from Dr Jonathan Williams the jury was told it was not possible to "confirm or refute whether the animal drowned".
The prosecution alleges Mr Stewart, who was due to marry Ms Bailey "imminently", murdered her for her money.
The author was worth "approaching £4m", the court heard earlier.
Mr Stewart denies charges of murder, preventing a lawful burial, fraud and three counts of perverting the cause of justice.
The jury has been sent home for the day.
The trial is expected to last seven weeks.


Live animal exports need to resume from the Port of Ramsgate following their suspension after the death of 45 sheep, the National Farmers' Union says.

On 12 September, 43 sheep were put down after a lorry was stopped at the port, and two more died in another incident.
"Exporting animals is a legal trade," Peter Garbutt, the NFU's chief livestock adviser, said.
But Thanet District Council, which imposed the ban, said construction work was needed before any resumption.
"The health and welfare of the animals through transit is the top priority of farmers."
Thanet District Council suspended live exports through the Port of Ramsgate on 20 September and live animals were sent abroad from the Port of Ipswich.
Mr Garbutt said anyone transporting animals had a duty to use the shortest route to reach their destination.
"We have made it clear that the port of Dover would be the most suitable location, but as the boat being used is unable to dock there currently, Ramsgate is the next best option available," he explained.
Thanet council said that live exports had been "suspended until further notice" and its lifting would depend on the construction of "suitable facilities" at the port.
Live animal exports have been suspended from the Port of Ipswich, a week after sheep were sent overseas.
RSPCA chief executive Gavin Grant said: "ABP [Associated British Ports] have acknowledged to the RSPCA that, like Ramsgate, their port did not have suitable facilities to help the animals should an emergency arise."
The 43 sheep that were destroyed were examined by vets who found that one had a broken leg, another was so sick it had to be put down, and 41 were severely lame.
None of the animals could reach their drinkers in the vehicle, the RSPCA said.
Six sheep fell in the water while being taken off the lorry, and four were rescued by RSPCA officers, but two drowned.
In another accident, two sheep died when a loading area floor collapsed as the livestock was being taken off a lorry.


Staff on Northern, Southern rail and Merseyrail have voted to strike in a dispute over the role of guards.

The RMT union announced the walkouts in a dispute with the firms over plans to remove guards from trains, which would become driver-only-operated (DOO).
Union officials, who confirmed the 24-hour strike on 13 March, say the move will make trains potentially dangerous.
The Office of Road and Rail insists they are safe provided the right equipment and training is given.
As well as walking out on strike, Merseyrail members will also not work any "rest days" from Monday 7 March indefinitely.
RMT general secretary Mick Cash said the result "sends out the clearest possible message" that the union "is prepared to stand up and fight for public safety and the guard guarantee".
He said the union's position on DOO "is perfectly clear" - "we will not agree to any introduction of DOO".
Arriva Rail North, which operates Northern trains, provides services across the north of England.
Merseyrail plans to introduce a new fleet of 52 (DOO) trains from 2020 and said none of the permanent guards or guard managers would lose their jobs.
The union said more than 81% of members at Northern and Merseyrail voted for strike action and more than 93% voted for action short of a strike.
A spokesman for Northern said the strike announcement "is a shame" and the firm's "aim is to reach a constructive resolution" and "protect jobs and pay".
A Merseyrail spokeswoman said the firm has "pledged to do everything we can to bring the dispute to a satisfactory and swift conclusion" and is "committed to continuing dialogue with the RMT".
Mr Cash said the union had no option but to strike again following "the abject failure by Southern rail to meet with us".
But, Southern said: "They say they want to talk, but they are hell-bent on further strike misery and causing disruption."
Parent company Govia Thameslink Railway (GTR) said news of a further strike on what would be the 30th day of RMT strike action was "clearly disappointing".
"We asked the RMT executive to suspend any further action... so that talks could take place, instead they have chosen to put their members through even more pointless industrial action."
Last week, the drivers' union Aslef met Southern for talks after its members rejected a deal.
It said it was working to ensure there were no more drivers' walkouts, but it still has a mandate to strike.
The BBC understands further discussions are being held with Aslef this week.


Several hundred people have gathered in New York's Times Square to protest at this week's Congressional hearings on the US Muslim community.

The hearings will look at the extent of radicalisation within the community and the response on that issue of Muslim leaders.
Muslim organisations say they are being unfairly singled out.
The hearings are in response to such events as the Fort Hood shootings and the Times Square car bomb plot.
The BBC's Tom Burridge in Washington says the protesters braved the rain to march on the streets of New York, many carrying banners reading "Today I am a Muslim too".
In the hearings, Peter King - a Republican Congressman and chair of the homeland security committee - has called several witnesses to testify about "the extent of radicalisation within the American Muslim community".
Mr King, who represents New York, claims some Muslim leaders are not doing enough to help the police and the FBI investigate terror plots which originate in the US.
Our correspondent says cases such as that of Pakistan-born US citizen Faisal Shahzad, who tried to blow up a car bomb in New York's Times Square last year, and Virginia-born US army Maj Nidal Hasan, who allegedly killed 13 people on a shooting spree at Fort Hood, Texas, in 2009, have changed political language and thinking in the US.
Politicians, the police and people are talking about a relatively new, homegrown threat, he says.
The protesters in New York and others fear the hearings will only increase Islamaphobia in America.
Hip-hop mogul Russell Simmons and Imam Feisal Abdul Rauf, who led the campaign to build an Islamic centre near the destroyed World Trade Center site, addressed the Times Square crowd.
"Our real enemy is not Islam or Muslims," said Imam Rauf. "The enemy is extremism and radicalism and radical ideology."
Muslim Democratic Congressman Andre Carson said he wanted to tell "the Peter Kings of the world, we will not take your xenophobic behaviour".
Mr King's language on this subject has often proved inflammatory, our correspondent says, and many believe the witnesses he has called to speak at the hearings do not represent mainstream Muslims.


Making science appeal to more girls will help the Welsh economy, the pro vice chancellor of Swansea University has said.

More than 350 scientists will attend the four-day British Science Festival at Swansea University from Tuesday.
It features talks and lectures from experts in different fields.
Hilary Lappin-Scott said there was a shortage of core workers in Wales and it was important to bring in more girls and keep women in those careers.
The university is running a session on promoting women in science and how to get girls interested.
Ms Lappin-Scott, who is also a microbiologist, told BBC Radio Wales: "I'm so committed to getting our young girls through the Swansea region and south Wales so that they get a passion for science - that they meet women scientists and engineers just like me and others and realise we're just pretty normal people really, and then we can have a bright future."
"Bringing in more girls and keeping women in stem careers, it'll make such a difference to our Welsh economy."
She added that making the stem subjects science, technology, maths and engineering "cool" was key.
"We do need all to work with our young children and give support to school teachers and parents.
"Maths, science, these are at the base of everything we do in everyday life. [There are] ways that we can make science cool as well, and you come along to the festival and you get that by the bucket load," she told Good Morning Wales.


A former Malaysian diplomat in New Zealand has pleaded guilty to indecently assaulting a woman in Wellington last year.

Prosecutors said Muhammad Rizalman bin Ismail entered a woman's flat, removed his trousers and underwear, and went into her bedroom.
The two engaged in a struggle and the woman eventually called the police.
He had earlier pleaded not guilty to more serious charges including assault with intent to rape.
He faces a maximum of seven years in prison.
Mr Muhammad Rizalman's lawyers have said that he was mentally unwell at the time.
The incident occurred in May last year when Mr Rizalman was a staff assistant for defence at the Malaysia High Commission.
He was arrested and charged at the time, but returned to Malaysia less than two weeks later under diplomatic immunity protection.
His departure sparked anger in Wellington and a disagreement with Malaysia on how he was able to exercise diplomatic immunity for his exit. Mr Rizalman was eventually extradited back to New Zealand to face trial.
A government inquiry was conducted on the diplomatic incident and the results will be made public after the trial, reported New Zealand Herald.


A jury in Los Angeles has convicted a female police officer of assault for repeatedly kicking a handcuffed woman who died soon afterwards.

Mary O'Callaghan, 50, now faces up to three years in jail. She has pleaded not guilty and is expected to appeal.
The case centred on a video recording, showing O'Callaghan hitting 35-year-old Alesia Thomas in the throat, abdomen and groin during the arrest in 2012.
Ms Thomas later lost consciousness and died in hospital.
A post mortem examination found traces of cocaine in her body, but the cause of death was listed as undetermined.
The jury in Los Angeles, California, reached the guilty verdict after two days of deliberations.
The police officer - who has been relieved of duty without pay after the incident - is now expected to be sentenced on 23 July.
Her lawyer Robert Rico said her client would appeal.
The defence team acknowledged that the footage showed an "ugly" scene, but said their client's use of force was "reasonable, justified and necessary" because Ms Thomas was not complying with the officer's orders.
The lawyers also stressed that O'Callaghan had an exemplary record during her 19 years of service.
The police woman went to arrest Ms Thomas on suspicion that she abandoned her two children.
The incident was caught on video by a dashboard camera in a police car.
O'Callaghan was not charged with killing Ms Thomas.
The US has recently seen a number of controversial cases when police officers used excessive force.
Recent data collected by the Washington Post newspaper suggests the number of people shot by US police is twice as high as official figures claim.
The paper said that during the first five months of this year, 385 people - more than two a day - were killed.
The number of black people was disproportionately high among the victims, especially unarmed ones.


A Scots nurse who was treated for Ebola in 2014 is expected to spend a second day in a Glasgow hospital despite testing negative for the disease.

Pauline Cafferkey, 40, was taken to the city's Queen Elizabeth University Hospital under police escort on Thursday morning after becoming unwell.
She is in a stable condition and medics say there is no danger to the public.
This is the fourth time Ms Cafferkey has been in hospital since returning to the UK from Sierra Leone two years ago.
On Thursday, NHS Greater Glasgow said: "Pauline Cafferkey was admitted to the Queen Elizabeth University Hospital this morning under the care of the Infectious Diseases Unit.
"Due to Ms Cafferkey's past medical history, appropriate precautionary measures were taken whilst further investigations were carried out.
"We are pleased to report that tests for the Ebola virus are negative. She remains in a stable condition in the Queen Elizabeth University Hospital. We want to repeat our previous reassurance that there is no risk to the public."
On Friday, the health board said it did not plan to issue any further updates on Ms Cafferkey's condition as she did not have Ebola, there was no public risk and they must respect her confidentiality as a patient.
Ms Cafferkey contracted Ebola while working as part of a UK team at the Kerry Town Ebola treatment centre in Sierra Leone.
She spent almost a month in isolation at the Royal Free hospital in London at the beginning of 2015 after the virus was detected when she arrived back in the UK.
Ms Cafferkey was later discharged after apparently making a full recovery, and in March 2015 returned to work as a public health nurse at Blantyre Health Centre in South Lanarkshire.
But it was later discovered that the virus was still present in her body, and she was readmitted to the same London hospital in October 2015.
She again recovered, before being treated at the Royal Free for a third time in February of this year due to a further complication related to her initial Ebola infection.
More recently, the nurse faced a number of misconduct charges by the Nursing and Midwifery Council (NMC).
These were for allegedly allowing a wrong temperature to be recorded during the screening process at Heathrow on her arrival back in the UK from Sierra Leone in 2014.
The NMC's conduct and competence panel dismissed all charges at a hearing in Edinburgh last month after being told that Ms Cafferkey's judgement had been impaired by illness.


Children went missing from council care in south-west England more than 350 times in the past five years, official figures have revealed.

One child aged six was missing for four days, while a teenager disappeared for 529 days, freedom of information requests have shown.
The NSPCC said the figures were "hugely concerning" as missing children are at risk of sexual exploitation.
Councils said they worked with agencies to protect and find them.
The data shows many of the children - who were mostly teenagers - went missing on multiple occasions.
Source: Freedom of information requests
Tom Rahilly, from the NSPCC, said: "Children go missing for many reasons - they're being bullied, they've been put in a home miles from their family and they miss them and their friends, or they just don't trust staff enough to tell them where they are.
"Many will have been abused before being placed in care and they need a lot of attention and protection."
In Torbay a 15-year-old disappeared on 11 separate occasions last year.
Torbay Council said it could not comment on individual cases but care plans were reviewed to ensure children and placements were matched correctly.
Plymouth City Council said: "In the case of a 16-year-old who was missing for 529 days, this refers to a young person from another country who did not want to remain in our care.
"We worked with police and other agencies to ensure that we followed all the necessary safeguarding procedures."
The council added it had a "thorough training programme" for foster carers and specialist support for those children affected.
Devon County Council said: "The number of children that have gone missing while in our care is very small, less than 3%, but any is too many."
It added that all children's social workers were undergoing new training to help them better support vulnerable young people.


Sir Elton John has announced he will perform in Edinburgh next year.

The singer's 'Wonderful Crazy Night' show will be the first music concert at the city's Meadowbank Stadium since 2007.
At least 18,500 tickets will go on sale on Friday for the show on Saturday 25 June. The Foo Fighters, Kaiser Chiefs and Prince have played at Meadowbank.
He is also playing in Exeter, Henley, Leicester, Lincoln, Liverpool and Oxford next summer.
Sir Elton said: "The simple truth is I want to spend more time with my family, and I am only too aware of just how precious the time ahead is.
"My sons are growing up so quickly; their early years are just flying by and I want to be there with them.
"So these concerts will give me the chance to thank the Scottish audiences who have been so faithful to me over these many decades.
"We cannot get to everyone, but I am going to try. Edinburgh has always been a very special place for me to play.
"I did my first ever truly solo show at the Playhouse back in 1976, and it also just happens to be where my guitarist and Music Director Davey Johnstone is from, so it's a very special city for me and the band."
David Milne, chairman of Edinburgh Leisure said: "Meadowbank Stadium has a rich history hosting a myriad of sporting events over the years including the 1970s and '86 Commonwealth Games and the 2012 Paralympic Torch Relay and also various music greats including the Foo Fighters, Kaiser Chiefs and Prince.
"It's an honour that Sir Elton John has chosen Meadowbank as the Scottish location for his 2016 tour and a rare opportunity for his Scottish fans to catch this legendary musician in such an iconic venue."
Richard Lewis, Edinburgh city council's convener of culture and sport, said: "We are absolutely delighted that Sir Elton John has chosen Meadowbank Stadium to host this concert.
"It's a real coup for both Meadowbank and Edinburgh to have one of the world's greatest music stars come to Scotland's capital city.
"I'm sure his legion of fans and the Edinburgh public will all agree this concert is the perfect way to kick start the festival scene and will really get the summer party in the Capital started."


A school bus driver whose vehicle became stranded in floodwater with 23 pupils on board had ignored two "road closed" signs, a court has heard.

York Crown Court was told the bus ended up in deep water between Newton-on-Ouse and Tollerton, near York, on 5 January.
It happened after what Judge Paul Batty QC described as "floods of biblical proportions" in the area.
Bus driver Graham Jones, 43, argues it was a "genuine mistake" and denies one charge of dangerous driving.
Prosecutor Graham O'Sullivan said the bus had been transporting the pupils on an eight-mile (12km) journey to Easingwold School on the first day of school following the Christmas holiday.
He said: "Mr Jones had driven through two 'road closed' signs."
Mr O'Sullivan said Mr Jones had driven through one section of flooded road but became stuck while driving through a second stretch.
The former Army driver, of Linton Woods Lane, Linton-on-Ouse, said he did not think the water was deep enough to cause him any difficulties.
He said the vehicle became stuck in a ditch as he tried to reverse after realising floodwater was coming into the bus.
When asked by the prosecutor if the way he drove was dangerous, Mr Jones replied: "I did not put the children's lives in danger.
"No, I did not class it as dangerous."
Mr O'Sullivan said Mr Jones had driven through floodwater despite not knowing the depth or breadth of it or the effect it might have on his bus.
"It is clear that someone who is driving in that way, risking the safety of his passengers and himself, is driving dangerously," he said.
The secondary school pupils on board were not injured but had to be rescued from the bus by North Yorkshire Fire & Rescue.
The trial continues.


Gravity-defying stacks of stones were created at the first European Stone Stacking Championships.

Competitors from across the UK, France and Spain took part in the contest at Dunbar last weekend.
Organiser Steve Hill said stone stacking was "the most natural form of street art you can find" and the artists' creations were "breathtaking".
The overall winner was Pedro Duran, of Spain, who managed to balance 33 rocks in one stack.


Notts County have completed the signing of Carl Dickinson on a two-year contract after the defender rejected a new deal at Port Vale.

Dickinson, 29, was Vale's captain and made 143 appearances during a three-year spell at the club.
He links up again with former Vale team-mate Richard Duffy, who joined Notts earlier this week from Eastleigh.
"I'm really looking forward to it and can't wait to get going," Dickinson told the Magpies' website.
"I'm a leader. I like to be loud in the dressing room and get the lads going.
"I'm hardworking, wear my heart on my sleeve and give everything, day in, day out."
Dickinson has also had spells at Watford and Stoke City during his career.
He was one of 13 out-of-contact players offered a pay cut by Vale, with several opting to move on.

Shares in Admiral fell 6% after the insurer said the rising cost of personal injury claims hit profits.

The firm's pre-tax profits rose 2% to £193m in the six months to the end of June 2017, as the number of UK insurance customers rose 11%.
However, changes to the way payments are made to accident victims - the Ogden rate - meant higher costs.
The changing rate weighed on profits last year, and Admiral said the impact had continued into 2017.
"Most of the adverse impact from the increase in the costs of large injury claims was in our 2016 second half result," said its chief executive David Stevens in a statement.
"However, some extra costs carry into 2017. In these circumstances, we are happy to report a marginal increase in profitability and to deliver a more material increase in the underlying dividend," he said.
The company estimated that the cost of the Ogden rate changes would be £150m, unchanged from six months earlier.
The government has been consulting on how the Ogden rate should be set, although a final decision has been delayed.
Admiral also reported a 15% rise in group turnover to £1.45bn, and net revenue of £550m, up 8%.
Mr Stevens said: "The first half of 2017 saw Admiral ambitious in pursuit of both immediate and longer-term growth opportunities."
However, investors were disappointed at the figures.
Admiral's shares fell as much as 7% in early trading, making the stock the worst performer on the FTSE 100. They finished 6% down on the day at £20.55.


Harry Styles has reportedly landed his first film role in Christopher Nolan's war drama 'Dunkirk'.

The 22-year-old singer will star in the film, according to US magazine Variety, but it's thought to be a small part.
The drama, which is due for release in 2017, will recreate the events of the World War II evacuation of the French city Dunkirk in 1940.
Styles will appear alongside British actors Tom Hardy, Oscar-winner Mark Rylance and Sir Kenneth Branagh in the film.
Warner Bros, who are making the movie, are yet to comment on Harry's role. Newsround has contacted a representative for Styles for comment.
Harry shot to fame in 2010 when he became a member of the pop group One Direction on the British talent show, The X Factor.
The four members are currently on a year-long break from the band, which began after they released their fifth album in March 2016.


An explosion at a fireworks market outside Mexico City has killed at least 31 people, officials say.

More than 70 others were injured as the blast hit the San Pablito fireworks market in Tultepec, about 20 miles (32km) outside the city.
Video from the scene showed a large number of fireworks rocketing into the air as they caught fire.
Dozens of paramedics and police attended the scene. The cause of the explosions is not yet known.
Locals have been told to avoid the area and keep roads clear.
Eruviel Avila, governor of the State of Mexico, said some children had suffered burns to more than 90% of their bodies and they were being sent to the US city of Galveston, Texas, for specialised treatment.
Most of those killed are so badly burned their bodies will have to be identified using DNA testing, he added.
Fireworks continued to explode after the initial blast, as smoke billowed from the area in thick black clouds. The market had contained up to 300 tonnes of fireworks, Mexican media reported.
Photos from police and medical personnel at the scene showed several injured people among the destroyed market stalls, with brick buildings scorched by the heat.
"The sound of blasts started to go off and we thought it was a nearby fireworks workshop," local resident Alejandra Pretel told the AFP news agency.
However, she said it soon became clear the entire market was at risk.
"My neighbours said they felt everything shake, but I didn't realise because I was running away," she said.
Angelica Coss, 25, said the explosions sounded "like a plane had crashed, like bombs were being dropped".
"I went up to the roof of my place and others were already there and we saw the market was blowing up. And all the smoke started to cover us," she said.
The president of Mexico, Enrique Pena Nieto, tweeted condolences to the families of the victims and wished a speedy recovery to the injured.
He also said members of the defence forces were assisting in the emergency.
The San Pablito market was heavily damaged by similar fires in September 2005, when a chain of explosions just before the country's independence day celebrations injured dozens of people.


The front of England's oldest hotel, which was destroyed by fire last October, is set to be restored.

A blaze damaged buildings on Cathedral Green in Exeter before spreading to the Royal Clarence Hotel, which dates back to 1769.
Architects say the new facade has been designed to stay as true as possible to the original.
The rebuilding of the hotel is expected to take 18 months to complete and it is due to reopen in 2019.
Owner Andrew Brownsword said some features like iron work and stained glass windows would be fully restored.
He said: "This is such a wonderful moment, after the initial heartbreak and months of deconstruction, to start to look towards to the future and to restoring the Royal Clarence's historic frontage."
Architect David Shatwell said: "Having taken every effort to stabilise the building, save as much as possible of what remains and prepare detailed research into the history of the building... we are delighted to now be taking the first steps toward rebuilding this beautiful building."
The plans for the facade will be on display at St Martin's Church in Cathedral Close between 14:00 and 20:00 on Wednesday, 26 July.
The plans for the interior of the hotel are still being worked on and they will need to be approved before work begins.


Mobile phone firm Three has been fined Â£1.9m for weaknesses in its system that is supposed to ensure anyone can make emergency calls at any time.

A loss of service in 2016 revealed that uninterrupted access to emergency calls was vulnerable to a single technical problem, regulator Ofcom said.
Its investigation concluded that Three did not act recklessly, but the issue could be reasonably be avoided.
The company said it had strengthened its systems.
Gaucho Rasmussen, Ofcom's enforcement and investigations director, said: "Telephone access to the emergency services is extremely important, because failures can have serious consequences for people's safety and wellbeing.
"This fine serves as a clear warning to the wider telecoms industry. Providers must take all necessary steps to ensure uninterrupted access to emergency services."
In a statement, Three said: "Ofcom identified this vulnerability when investigating a separate, unprecedented and unforeseeable October 2016 fibre break outage on Three's network. This resulted in a temporary loss of emergency call services affecting some customers. Three took immediate action and the issue was quickly resolved.
"Ofcom recognises that the circumstances surrounding the October 2016 fibre break outage were exceptional and outside of Three's control."


It was "extraordinary" the environment regulator decided to sell £39m of timber to a sawmill company without a proper business case, AMs have said.

Other firms were unable to bid for the Natural Resources Wales contract, which may have broken EU competition laws.
Public Accounts Committee chairman Nick Ramsay called it "a serious error of judgement".
NRW accepted the recommendations of the committee and said it would address them.
The report, out on Thursday, also said it had "serious concerns" only one official at the regulator was in charge of the deal.
"Given the sums of public money involved we find it to be wholly unacceptable that a full, open and fair retendering process did not take place," it adds.
The company, which has not been named, failed to open a new saw line in Wales as it was expected to as part of a 10-year contract with NRW.
When it met the committee in March, NRW could not say whether the obligation had been met, despite the deadline for completion being a few days away.
The committee recommended NRW review the way it awards contracts and its approach towards EU state aid rules, which limit public funding for private-sector companies.
Lawyers told NRW the rules had not been broken, but AMs heard legal advice was not sought until three years after the contract was awarded.
NRW also said it needed to award contracts quickly to control the rapid spread of the disease Phytophthora Ramorum in larch trees.
The official responsible was the former director of the Forestry Commission, one of the organisations that merged into NRW in 2013.
An NRW spokesman said it was addressing concerns over the contract raised by the auditor general for Wales in March and would ensure its "action plan" also covered all the committees recommendations "which we accept in full".
"We accept that there are matters that need to be addressed but there has been no complacency by NRW in responding to the issues raised by the auditor general; we were dealing with a very serious situation with larch disease at the time and needed to act quickly," he said.
"Our recent timber marketing plan has significantly changed the way we operate and we have incorporated the lessons learned from the previous contracts."
In May, the UK Forest Products Association said there was "serious concern" in the timber industry over the deal.


JK Rowling is to receive a prestigious award from literary and human rights group Pen America.

The Harry Potter author will be presented with the Pen/Allen Foundation Literary Service Award on 16 May at the group's annual spring gala in New York.
Pen (Poets, Essayists and Novelists) said it was honouring the author in recognition of her support for free expression and charitable causes.
Previous winners have included Sir Salman Rushdie and Sir Tom Stoppard.
Pen America states it aims "to ensure that people everywhere have the freedom to create literature, to convey information and ideas, to express their views, and to make it possible for everyone to access the views, ideas, and literatures of others".
Its Literary Service Award award is given annually to authors whose work fights repression and censorship around the globe.
Rowling is the founder of the charitable trust Volant, which supports multiple sclerosis research.
She is also the founder of the non-profit-making organisation Lumos, which works to reconnect children who have been in institutional care with life within a family.
A statement from the organisation said: "Since her rise from single mother to literary superstar, JK Rowling has used her talents and stature as a writer to fight inequality on both a local and global level.
"Her charitable trust, Volant, supports causes in the United Kingdom and abroad that alleviate social exclusion, with particular emphasis on women and children."
Rowling expressed her pride at having been chosen to receive the award.
"I'm deeply honoured to receive this award and humbled that my work has been recognised as having moral value by an organisation I so admire," she said.
"I've long been a supporter of Pen, which does invaluable work on behalf of imprisoned writers and in defence of freedom of speech."
Prize-winning author Andrew Solomon, president of Pen America added that Rowling's writing provided a wealth of "imagination, empathy, humour, and a love of reading, along the way revealing moral choices that help us understand ourselves".
He added: "Through their experiences with Rowling both on and off the page, countless children have learned not only the power of speaking their own minds, but the critical importance of hearing others."
At the May ceremony, Pen will also honour Hachette Books chief executive Michael Pietsch for his anti-censorship work. In 2015, he encouraged American publishers to resist censorship in China.
And in the coming weeks, Pen will announce its selection for its Freedom to Write Award and the Pen/James and Toni C Goodale Freedom of Expression and Courage Award.


A woman dying from cancer has married her partner after well-wishers helped provide free catering, flowers, a wedding dress and venue hire.

Sarah Lowndes, from Derby, tied the knot with fiancé David Moore at Makeney Hall in Milford, Derbyshire.
She was diagnosed with breast cancer in 2010, and the disease later spread.
The couple, who met driving buses, were unable to pay for the wedding due to her illness, but were inundated with help to fund the event.
Mother-of-two Ms Lowndes, who met Mr Moore two years after her first diagnosis, said the ceremony went "smoothly", despite forgetting her words at one point. She thanked charity Wish for a Wedding for their help in putting on the ceremony.
"If it wasn't for the charity we wouldn't be where we are today," she said.
Mr Moore said he felt "absolutely brilliant" after the wedding.
"It's the best day of my life," he said.
Wish for a Wedding's Alison Walker, who first met David and Sarah nine weeks ago, said it was a "very, very emotional" event.
"[The ceremony] was beautiful. I didn't expect David to be quite as emotional as he was - I thought Sarah was going to be the one who would be full of tears - but it was lovely seeing them up there," she said.


Actor Lenny Henry has criticised the BBC's plans to increase on-screen diversity by 5% in the next three years.

Henry said the black, Asian and minority ethnic (BAME) community had "initiative fatigue".
"Tony Hall's announcement last week is something but with massive respect it's on an old model that doesn't work," he added.
The BBC wants to increase BAME on-air talent to one in six people by 2017.
Speaking at a culture, media and sport select committee hearing, Henry said there had been "29 initiatives at the BBC in the last 15 years and numbers (of people from BAME backgrounds working in the industry) have gone down".
He added: "Idris Elba and Chiwetel Ejiofor didn't need more training. They just needed a break."
Director general Lord Hall's announcement last Friday also included a series of targets for staff representation off-air and several other initiatives.
In addition to a Â£2.1m development fund, the BBC is bringing together a group of experts, including Henry, Baroness Tanni Grey-Thompson, Asian Network presenter Nihal and Lady Benjamin, to form an Independent Diversity Action Group, chaired by Lord Hall.
"I think the group will be tough-minded," Lord Hall said on Friday. "But it's good to have people who are there to support you, but also say you can do better here."
Henry was addressing the select committee during its wider review of the future of the BBC ahead of the Charter Renewal in 2016/17.
The actor and comedian wants the broadcasting industry to adopt the plan he launched at Bafta earlier this year to increase BAME representation - dubbed the Henry plan - based on the model that media watchdog Ofcom uses to classify programmes made in the nations and regions.
In response to his comments, a BBC spokesperson said: "Last week we set out far reaching plans that we believe will make a tangible difference - we will work hard to deliver them and of course reserve the option of going further if we fall short, but people should judge us on progress over the coming months and years before concluding the need for even more measures."
Henry's appearance at the select committee comes after the acting head of the BBC Trust, Diane Coyle, said the BBC's flagship soap EastEnders is "almost twice" as white as the real east London.
The BBC's audience council in England had compared the population of Walthamstow in east London with Walford, the fictional home of EastEnders.
Ms Coyle said it would be "daft" for the show to be a "perfect replica" of the real world.
But she added it was "important to ask whether the BBC can do more in its popular output to provide an authentic portrayal of life in modern Britain".
Referring to her comments that she made during a speech at the London School of Economics on Monday, Henry said: "EastEnders is the most ethnically diverse of any soap."
The BBC said: "We agree with the trust that EastEnders has one of the most diverse casts on British television and that it would be daft to suggest that the programme needs to be a perfect replica of a particular postcode."
Ms Coyle is in the running to become head of the BBC Trust after Lord Patten stepped down due to ill health.


Japanese scientists believe they have established the identity of a "missing element" within the Earth's core.

They have been searching for the element for decades, believing it makes up a significant proportion of our planet's centre, after iron and nickel.
Now by recreating the high temperatures and pressures found in the deep interior, experiments suggest the most likely candidate is silicon.
The discovery could help us to better understand how our world formed.
Lead researcher Eiji Ohtani from Tohoku University told BBC News: "We believe that silicon is a major element - about 5% [of the Earth's inner core] by weight could be silicon dissolved into the iron-nickel alloys."
Hard to reach
The innermost part of Earth is thought to be a solid ball with a radius of about 1,200km (745 miles).
It is far too deep to investigate directly, so instead scientists study how seismic waves pass through this region to tell them something of its make-up.
It is mainly composed of iron, which makes up an estimated 85% of its weight, and nickel, which accounts for about 10% of the core.
To investigate the unaccounted for 5% of the core, Eiji Ohtani and his team created alloys of iron and nickel and mixed them with silicon.
They then subjected them to the immense pressures and temperatures that exist in the inner core.
They discovered that this mixture matched what was seen in the Earth's interior with seismic data.
Prof Ohtani said more work was needed to confirm the presence of silicon and that it did not rule out the presence of other elements.
Core formation
Commenting on the research, Prof Simon Redfern from the University of Cambridge, UK, said:  "These difficult experiments are really exciting because they can provide a window into what Earth's interior was like soon after it first formed, 4.5 billion years ago, when the core first started to separate from the rocky parts of Earth.
"But other workers have recently suggested that oxygen might also be important in the core."
He said that knowing what is there could help scientists to better understand the conditions that prevailed during the formation of the Earth.
In particular whether the early interior was one where oxygen was greatly limited - known as reducing conditions. Or whether oxygen was in abundance, which is described as oxidising.
If a larger amount of silicon had been incorporated in Earth's core more than four billion years ago, as suggested by Prof Ohtani's results, that would have left the rest of the planet relatively oxygen rich.
But if, instead, oxygen was sucked into the core that would leave the rocky mantle surrounding the core depleted of the element.
Prof Redfern said: "In a way, these two options are real alternatives that depend a lot on the conditions prevailing when Earth's core first began to form.
"The most recent results add to our understanding, but I suspect that they are by no means the last word on the story."
Prof Ohtani presented his research to the recent Fall Meeting of the American Geophysical Union in San Francisco.

Alex Davies hit a century as Lancashire reached 278-5 in reply to Hampshire's 395 on day two at Old Trafford.

The visitors added a further 44 to the overnight score before being dismissed, leaving South African Kyle Abbott just three short of a maiden century.
Lancashire then fell to 69-3 but opener Davies made 115 to steady the innings, helped by 76 not out from Dane Vilas.
Seamer Gareth Berg took 2-51 for Hampshire, while Abbott, Brad Taylor and James Vince claimed a wicket each.
In the morning session, England's all-time record wicket-taker James Anderson claimed a second scalp of the match, dismissing Taylor before Ryan McLaren wrapped up the Hampshire innings with the wicket of Matt Salisbury.
Rob Jones, Luke Procter and skipper Steven Croft all failed to reach double figures at the top of the order for Lancashire.
But, despite two dropped catches and a missed run-out opportunity, Davies reached his century from 152 balls before he was caught at deep square leg by Michael Carberry off James Vince.
Davies had help from Shivnarine Chanderpaul, neatly stumped by Lewis McManus for 33, in a stand of 74 in 16 overs before Vilas then put on 55 with McLaren (23 not out) to help the hosts close 117 runs behind.
Lancashire batsman Alex Davies told BBC Radio Lancashire:
"It feels really nice to get another hundred. It kind of feels I've left some runs out there, but I was getting really tired towards the end of the day and it was a lack of concentration.
"I'm pleased with the innings and pleased with the position we're in but you always want a few more runs as I haven't got any runs in the last couple of games.
"I've always felt like a natural opener but it's a question of where the team wants me to bat.
"The pitch is good. Typical Old Trafford. It's just a question of whether it goes on day four."
Hampshire pace bowler Kyle Abbott told BBC Radio Solent:
"I was close to my first hundred but it just wasn't meant to happen. It isn't the end of the world.
"My game plan is to be positive and I find I defend better when I adopt that approach. I'm just pushing my limits and seeing what I am capable of.
"I'd absolutely like to get a first-class hundred. I thought it was there today. At least I now know the process and what it takes to get there.
"The scoring's been quick so it's difficult to know what a good score is. The wicket is good but it's just staring to get a bit variable and I'm sure that will become important as the game progresses."


Turkey has said it wants to re-establish good relations with Syria - in an apparent reversal of its policy towards its war-stricken neighbour.

Up to now Turkey's government has been pressing hard for the overthrow of the Syrian President, Bashar al-Assad.
But Turkish Prime Minister Binali Yildirim insisted good ties with Syria were needed "for the fight against terrorism" and stability in the region.
There has so far been no public response from the Syrian government.
Turkey has recently moved to end rifts with both Russia and Israel.
Diplomatic ties between Turkey and Syria were severed after the uprising against Mr Assad began in 2011.
Turkey is a key backer of both the political and armed Syrian opposition and has faced the burden of hosting more than 2.7 million refugees.
In December, Turkish President Recep Tayyip Erdogan alleged that Mr Assad had "mercilessly killed 400,000 innocent people".
But in comments broadcast live on television on Wednesday, Mr Yildirim said: "It is our greatest and irrevocable goal: developing good relations with Syria and Iraq, and all our neighbours that surround the Mediterranean and the Black Sea."
"We normalised relations with Russia and Israel. I'm sure we will normalise relations with Syria as well. For the fight against terrorism to succeed, stability needs to return to Syria and Iraq."
There have also been reports in the local media of Turkish and Syrian diplomats holding talks.
But in an interview with BBC HARDtalk, Mr Yildirim stressed that any shift in Turkey's policy towards Syria was dependent on Mr Assad.
"Things need to change in Syria, but first of all Assad should change. Unless Assad changes, nothing changes in Turkey," he said.
Mr Yildirim accused the Syrian leader of creating the conditions that gave rise to the jihadist group, Islamic State (IS), which controls large parts of Syria and neighbouring Iraq.
"As long as Assad is there, the problem won't be solved," he said. "We'll have some other terrorist organisation coming up because it's the attitude of the Syrian regime which created [IS]."
Last month, Turkey normalised relations with Israel, ending a six-year rift over the killing by Israeli troops of 10 Turkish activists on a ship carrying aid for the Gaza Strip.
On the same day, Mr Erdogan apologised to Russia for shooting down a Russian warplane on the Turkish-Syrian border in November 2015.
Turkey's new initiative comes at a time of great political instability in the country, says the BBC's Katy Watson in Istanbul.
In the past year, it has been hit by a wave of deadly bombings blamed on Kurdish rebels and IS.
In a separate development, French diplomatic missions in Turkey cancelled their Bastille Day celebrations on Thursday for "security reasons", the consulate general in Istanbul said.
