UK Sport is under further scrutiny after its treatment of complaints about GB Taekwondo was questioned.

Concerns from English Institute of Sport (EIS) medical staff over coaches' practices led to a review in 2015.
The EIS has queried the review panel's independence and findings, although both UK Sport and GB Taekwondo say the review was carried out appropriately.
Taekwondo is the latest sport to be involved in a welfare controversy after cycling, swimming and canoeing.
Medical staff working with GB Taekwondo raised concerns to UK Sport with regard to concussion, weight loss and training loads, including claims that athletes were asked to train in saunas, reported City AM.
This led to GB Taekwondo commissioning an independent review, although the organisation was allowed to select its own panel. They chose not to interview any of the complainants or athletes, according to the paper, but had access to written submissions and medical notes.
The report published last year found no evidence to support the complaints or of poor practice.
A statement from the EIS said it had concerns over the independence of the panel - which was set up with funding agency UK Sport's help - the management of the review process and did not wholly agree with the findings of the final report.
"The EIS has continued to have a dialogue with UK Sport around these issues," it added.
The GB Taekwondo team enjoyed its best Olympic medal haul last year, when Jade Jones, Lutalo Muhammad and Bianca Walkden won gold, silver and bronze respectively in Rio.
GB Taekwondo says it "has no greater priority" than the health and wellbeing of athletes on its world-class programme.
"They are given an individualised training and competition plan as well as a bespoke nutrition and hydration programme which is underpinned by a robust weight management policy to ensure they are among the best prepared athletes in the world," it said.
"They travel with medical support at all times to ensure they are fully fit to compete in this demanding sport."
GB Taekwondo no longer uses EIS medical staff but says this change was planned before the claims were made, adding that improvements had been made to support athletes.
A UK Sport spokesperson said it took "appropriate and timely" action and there was not sufficient evidence to stand up the claims.
"That said we have asked our internal teams within UK Sport (performance and governance) to provide an extra emphasis in their monitoring in terms of both the world-class programme and GB Taekwondo's internal processes on athlete welfare/safeguarding," it said.
"We are also exploring how we can involve athletes more directly in providing their views on a confidential basis about both performance and services provided by practitioners."
The latest claims come amid concern over the culture of high-performance programmes in British sports.


Jeff Kinney, author of the Diary of a Wimpy Kid, has just released his tenth book.

19 November 2015 Last updated at 08:00 GMT
The series is based on character Greg Heffley and his life at school and adventures with his friends and family.
Jeff first came up with the idea for Diary of a Wimpy Kid in 1998 but it wasn't until six years later, that it was first published online.
Now his books have sold more than 150 million copies around the world.
He came in to Newsround HQ to answer some of your questions and tell us about his latest book.


Ian Poulter secured his first win of the year with a closing round of 65 at the WGC Champions in Shenzhen.

The Englishman, 36, who won his four games in Europe's Ryder Cup win in September, produced eight birdies in his first 15 holes to take control.

Overnight leaders Lee Westwood and Louis Oosthuizen only managed rounds of level par, and Poulter came from four shots back to win by two.
Ernie Els and Phil Mickelson were in a four-way tie for second.
United States duo Jason Dufner and Scott Piercy also finished two shots behind Poulter.
Poulter, who finished fourth at the BMW Masters last week, said: "It's been an amazing five or six weeks with the Ryder Cup and then coming here in good spirits.
"I played well last week and took a lot from that. I knew that if I stayed patient I'd be right there at the end.
"I feel confident with the putter right now. It's so nice to get my hands on another trophy and get back in the winner's circle."

2. Peter Hanson (Swe) -  2,642,524 euros
3. Justin Rose (Eng) - 2,566,323 euros
4. Ian Poulter (Eng) - 2,270,851 euros
5. Branden Grace (SA) - 2,081,961 euros
Westwood led by three shots in the early stages but a double bogey at the short fifth stopped his momentum, before three bogeys on the back nine ended his hopes and he finished tied sixth with Oosthuizen.
With the overnight leaders out of contention, Mickelson, Els and defending champion Martin Kaymer were Poulter's biggest threats, only for the German to triple-bogey the short 17th.
Els, failed with a 45-foot birdie attempt at the last, with a bogey on the penultimate hole meaning Mickelson had to hole his second shot on the 18th to force a play-off.
The three-time Masters champion could only manage a par and now goes on to play at next week's Singapore Open.

"I'll see if I can improve one spot there," he said. "It was good for me to come back after having not played since the Ryder Cup and pick up where I left off."
Another man who will be in Singapore is Rory McIlroy, who along with Tiger Woods, skipped Mission Hills but holds a 800,000 euro lead at the top of the European Tour money list after nearest challengers Justin Rose and Peter Hanson finished in a tie for 24th.
McIlroy tweeted his congratulations to Poulter, saying: "Ballsy up and down at the last, wouldn't expect anything less!"
Poulter, only the second European after Darren Clarke to win two WGC events, has climbed to fourth in the Race to Dubai and 15 in the world rankings.
"Two world championships are great, of course, but a major is the biggest dream," he concluded. "People keep asking all the time 'when, when, when'. I don't know when and I'm trying really hard - I'll do my best next year."


Celtic have signed striker Colin Kazim-Richards from Dutch side Feyenoord on a two-and-a-half year deal.

The 29-year-old Turkey international is a replacement for Nadir Ciftci, who has been loaned out to Eskisehirspor until the end of the season.
Celtic earlier confirmed the signing of Manchester City winger Patrick Roberts on an 18-month loan deal.
The 18-year-old, who has played for England Under-19s, joined City in the summer from Fulham.
Kazim-Richards has scored over 50 goals in more than 350 club appearances across spells in England, Turkey, France, Greece and the Netherlands.
The London-born forward, who played for Bury, Brighton and Sheffield United early in his career before heading abroad, said he felt "privileged, thankful and ecstatic" after accepting Celtic's offer.

"To tell you the truth, I never wanted to come back to Britain," he said. "But once this opportunity came, it was an obvious decision.
"I have played at big clubs but this is one of the biggest. The fans can expect someone who will give 125% every day, not just on match-day. I'm really honoured to have this opportunity to come and show my abilities."
Roberts, meanwhile, is looking forward to some first-team action after being restricted to three appearances as a substitute for City this season.
"Manchester City know I need to be playing football and they were happy for me to come up here," said Roberts, who was sold to City for around £12m.
"Celtic are huge in Scotland and huge in Europe and this is what I want. I'm here for a long time and I want to develop. I want to do well for Celtic, win trophies and get into Europe.
"I'm very direct and quick. I like to get the fans off their seats, which I hope to do many times, and I like to score goals."
Ciftci, 23, joined the Scottish champions from Dundee United on a four-year deal in July but has found it hard to break into Ronny Deila's first team.
The Turkish striker will stay with Süper Lig side Eskisehirspor in his native country until the end of the current campaign.
Deila has already signed Denmark defender Erik Sviatchenko, who featured in Celtic's Scottish League Cup semi-final defeat by Ross County on Sunday.
Meanwhile, Celtic have sent teenage forward Aidan Nesbitt on loan to Premiership rivals Partick Thistle for the rest of the season.


A 12-year-old girl has been injured after being hit by a police car in Hampshire.

The vehicle, which was responding to an incident and had its siren and blue lights on, hit the girl on Gosport Road, Fareham just after 16:00 GMT, police said.
It is believed she suffered non-life threatening head injuries and was taken to hospital.
The force said officers from the road policing unit were investigating.


A marshal has told an inquiry that spectators screamed at him as he sought to stop a car rally because he thought the conditions were dangerous.

John Clayton, 72, said he wanted to halt the race during 2013's Snowman Rally because motorsport enthusiasts were standing too close to the track.
Mr Clayton managed to have the rally stopped but there were still cars on the track and one of them crashed.
Spectator Joy Robson, 51, from Skye, died after being injured in the crash.
A joint fatal accident inquiry is being held into the death of Mrs Robson as well as the deaths of three people - Iain Provan, Elizabeth Allan, both of Barrhead, and Len Stern, of Bearsden, - at the Jim Clark Rally near Coldstream in the Borders in 2014.
Mr Clayton, from Mull, said he wanted to stop the stage of the Snowman Rally near Drumnadrochit, south of Inverness, in order to keep enthusiasts standing at "inappropriate locations" safe.
He said there had not been an incident at this point, but felt he could not handle the situation if the rally continued.
Crown lawyer, advocate depute Andrew Brown QC, asked if people were "screaming" at him for trying to halt the event.
Mr Clayton replied: "Yes they were. And at other events people are screaming at you because you are spoiling their fun."
The inquiry heard how Mr Clayton was one of two marshals at a hairpin bend close to where Ms Robson was struck by a vehicle being driven by 31-year-old Graeme Schoneville.
The marshal asked for the rally to be stopped because he was concerned about the number of spectators arriving at the location, who were standing where it was not safe.
Mr Clayton told Mr Brown that he contacted the rally stage manager to convey his request.
He added: "I felt it was getting too dangerous. I was not happy with how things were developing."
The inquiry heard that Mr Clayton's request to stop the stage resulted in cars that had not started being stopped immediately.
However, there were six cars heading for the hairpin. The car which crashed was the fourth vehicle.
Mr Clayton said he heard a "bang bang" and saw the car spiralling up in the air.
The inquiry heard that the car went over the top of small trees before losing momentum and heading straight down..
The inquiry heard that people were running in all directions.
Mr Clayton told Mr Brown that following the collision involving Ms Robson, he helped a police inquiry into the circumstances surrounding the incident.
He said: "I gave a statement to the police. I spent about two hours in a police car speaking to officers back at the car park."
Mr Clayton told the inquiry that the incident had left event organisers traumatised.
He added: "I think everybody was in so much shock."
The inquiry, which is being heard before Sheriff Kenneth Maciver QC, continues.


At least eight people have been killed in clashes between Pakistani police and supporters of a prominent Islamic scholar in the city of Lahore.

Dozens more were injured as police fired shots and tear gas to disperse protesters at the offices of Tahirul Qadri. His supporters threw stones.
Two women died in the riots which are now under control, reports say.
Mr Qadri, who is based in Canada, plans to return to Pakistan next week to lead a campaign against corrupt politicians.
He led a "long march" on Islamabad in January last year, but the protest fizzled out with little result.
The BBC's M Ilyas Khan in Islamabad says Mr Qadri is seen by many as a political nuisance who lacks clout.
But he has the ability to gather supporters from his madrassas and is rumoured to have ties with the powerful ISI intelligence agency.
Police in Lahore say clashes broke out after supporters of the Pakistan Awami Tehreek (PAT), which is led by Mr Qadri, resisted attempts to clear barriers outside their leader's offices in the Model Town suburb on Monday night.
When the police brought in reinforcements in the morning, the confrontation grew, although the police insist they showed restraint, the BBC's Mike Wooldridge in Islamabad reports.
A number of arrests have been made.
The Chief Minister of Punjab, Shahbaz Sharif, has ordered a judicial inquiry.
"I am deeply saddened over the killings," Mr Sharif, who is also the brother of Prime Minister Nawaz Sharif, said.
"If I am held responsible, I will immediately resign because I cannot even imagine using force against anyone," he added.
Officials at Lahore's Jinnah Hospital said the bodies of those killed had bullet wounds.
Dr Abdul Rauf told the AFP news agency the hospital had "received 80 injured, 40 with bullet injuries and 40 with other wounds."
Some commentators have criticised the authorities for being heavy-handed in dealing with Mr Qadri's supporters.
They say the barricades had been there for over four years, and had been erected with the consent of the area residents to improve security.
Mr Qadri held a news conference via videolink from Canada to condemn the police raid on his headquarters in Lahore.
He said he remained undaunted and would arrive at Islamabad airport on Monday as planned.
He urged his followers to continue their protest, but remain peaceful and refrain from damaging property.
"The revolution that was to take time in coming will now arrive more quickly," he said. "These deaths will lead to the end of this government."


The widow of one of the Hillsborough disaster victims has told an inquest jury in Warrington it "robbed" her five children of their father.

Kathleen Thompson's husband Pat was one of the 96 people who died following overcrowding at the FA Cup semi-final in April 1989.
Mrs Thompson was one of the first of the victims' relatives to give a background statement to the court.
The remaining families will give their "pen portraits" later.
Coroner Lord Justice Goldring has called the disaster "the worst-ever at a British sports stadium".
It unfolded on 15 April 1989 during Liverpool's match against Nottingham Forest at Sheffield Wednesday's ground.
The inquests, set to last a year, were ordered after new evidence revealed by the Hillsborough Independent Panel led to the original inquest verdicts being quashed.
Profiles of all those who died
The background statements are the first time the court has heard how the disaster impacted on individual families.
Weeping as she spoke, Mrs Thompson said her husband, a 35-year-old railway guard, "was not a hooligan, but a hard-working family man".
She said he had been "a loving and generous man who treated me with love and respect, a larger-than-life character... and a smashing dad" to five children aged under six.
Opening proceedings, 41-year-old victim Arthur Horrocks' son Jon read out a statement from his mother Susan, in which she said Mr Horrocks had been "a wonderful husband and best friend... devoted and much loved".
The hearing was told Mr Horrocks loved music and had regularly visited the Cavern Club in Liverpool. He had attended every Liverpool home match.
Stephen Jones, whose wife Christine was one of seven women who died, said she had been an avid fan who organised coach trips to away matches and loved the atmosphere of the games.
He said the senior radiographer and Sunday school teacher had been "an amazing wife", who "dominated a room".
"She was effervescent, candid and lively," he said.
Wilf Whelan told the hearing about his son Ian, who was nicknamed "Ronnie" after his football hero, Liverpool midfielder Ronnie Whelan.
He said the 19-year-old "wasn't a football hooligan" but a music lover, who had left two red roses on the doorstep of his girlfriend on the day of the semi-final.
"Our family feel they've had to defend his good name for 25 years," he said.
Paying tribute to her brother, Roy Pemberton, Shirley Riley said the family had been left thinking about what he would have achieved, "a successful career, a family and many more dreams... we will never know".
She said her parents "never truly got over the loss" of their son, who had been "extremely precious and the apple of their eye".
Paula Ann Smith's brother Walter said they both attended Liverpool games, but as they only had one ticket for the semi-final he let his sister have it.
"I often think if I had been there with her, she would still be alive today," he said.
Christine McEvoy cried as she told the jury about her daughter, Basildon factory worker Marian McCabe.
She said the 21-year-old had been a "good and generous" woman who worked overtime to pay for tickets and who missed Mrs McEvoy's wedding to go to a game as "her greatest love was Liverpool Football Club".
The day's final two statements came from the families of partners Tracey Cox and Rick Jones.
Stephanie Conning, who survived the disaster, described her brother's 23-year-old girlfriend as "the sister I never had".
She said Tracey Cox's death had "permanently affected all our lives for the worst".
Doreen Jones, Rick's mother, cried as she told the hearing of her family's lives "changed forever that awful day".
"I could not imagine a life without Rick and I did not want to. It was a very dark place for us all," she said.
"My pain is centred on what Rick and Tracey missed and what their lives would have been like.
"After all, they only went to watch a football game."
Adjourning the proceedings until Monday, coroner Lord Justice Goldring told the jury the statements were "as emotional as I said they would be".
"They underline the individual tragedies," he said.


Wolves midfielder Prince Oniangue has joined French club Bastia on loan until the end of the season.

The Congo captain moved to Molineux from Reims last August for an undisclosed fee.
But the 28-year-old has only made 11 first-team appearances and none since a 1-0 defeat at Brighton in mid-October when he was substituted at half-time.
Bastia are currently 17th in the French top-flight, having won five of their 20 games so far this season.
"The deal has been done for him to join Bastia on loan until the end of the season, and then we will be able to revisit the situation and see what the future holds," Wolves sporting director Kevin Thelwell told the club website.
Head coach Paul Lambert is keen to reduce the size of his squad in January.
Dutch forward Ola John left Wolves on Friday, cutting short his loan spell from Benfica to join Spanish club Deportivo La Coruna on loan for the remainder of the season.

Aston Villa are all but relegated after a defeat by Bournemouth - their eighth in a row - left them 15 points from safety with five games left.

Steve Cook's close-range finish set the visitors on their way before Joshua King scored after a defensive mix-up.
Jordan Ayew reduced the deficit with a powerful shot beyond Artur Boruc.
Villa need to win their remaining five games to have any chance of staying up, but could be down before they play at Manchester United on 16 April.
The Birmingham side could be relegated on Sunday - for the first time in 29 years - if Sunderland beat league leaders Leicester.
Alternatively, Norwich, who are 17th in the Premier League table - 15 points clear of Villa - entertain fellow strugglers Sunderland at 12:45 BST on 16 April.
If the Canaries avoid defeat in that game, Villa will be relegated.
Reaction from Villa Park and the rest of Saturday's Premier League games
Relive the action from Villa Park
For 23 minutes on Saturday Villa were down before Jason Puncheon's 68th-minute winner for Crystal Palace against Norwich earned the Premier League's bottom club a temporary stay of execution.
Fans were in an unforgiving mood as the fractured relationship between home players and supporters continued.
There were thousands of empty seats at kick-off as some supporters chose to miss the first seven minutes in protest - seven being the number of times Villa have been champions of England.
Towards the end, other home fans were spotted waving white handkerchiefs - a sign of surrender - after another poor, careless performance.
Villa, who desperately needed a positive display to appease their disgruntled fans, set up to contain the Cherries yet were picked off at ease.
Villa gave a full Premier League debut to 20-year-old midfielder Jordan Lyden - though he lasted only 45 minutes before being replaced at the start of the second half.
By then the match was already as good as over for Villa following another performance in which they lacked leadership, character, fight and had only one shot on target.
In contrast, Bournemouth, who welcomed back forward Callum Wilson after a serious knee injury,  were bright and breezy.
Lewis Grabban forced a full-length save from Brad Guzan before Cook's finish from a short corner on the stroke of half-time gave them the lead.
The Cherries doubled their lead when Ciaran Clark was robbed by King, who went on to finish smartly - and although Villa went on to score a first goal in over seven and a half hours, the visitors held on comfortably.
Bournemouth were tipped for relegation at the stat of the season yet they are challenging for a top-half finish after reaching 41 points with five games left.
Aston Villa caretaker manager Eric Black, speaking to BBC Sport: "Not going down today is a small consolation. We've conceded poor goals, but we have to remain professional until the end.
Media playback is not supported on this device
"We didn't create as many chances as we would have liked. Ultimately, if you concede poor goals it will be hard to score.
"I'm sure it's not easy to play in that atmosphere, but there have only been two or three victories here this season so I won't be criticising the supporters.
"They turned out again today, which I find remarkable. This is certainly not down to the supporters."

Bournemouth manager Eddie Howe, tells BBC Sport: "This was really important for us. It was very nervy from both teams but I thought we dominated the ball and deserved it in the end.
"It was a difficult game to play in because of the toxic atmosphere. We made it that way with the way we started."
Villa's relegation will be confirmed if they fail to beat Manchester United at Old Trafford next Saturday - something they have not done since 2009.

Seven people have been charged as part of an investigation into a spate of arson attacks on the homes of serving police officers.

The attacks took place between April and July last year at addresses in Portadown, County Armagh, and Banbridge and Gilford in County Down.
The officers' homes and vehicles were attacked and in some cases destroyed.
Those charged were among nine people detained by police on Tuesday as part of the investigation.
Two men were charged with a number of offences on Wednesday evening.
They face charges of arson with intent to endanger life, conspiracy to cause an explosion and drugs offences.
The men will appear at Lisburn Magistrates' Court on Thursday.
Earlier on Wednesday, four men and a woman appeared at Craigavon Magistrates' Court on arson and drugs-related offences.
The woman is 21 while the others are aged 17, 20, 36 and 51.
They faced a number of charges, including conspiracy to commit arson and conspiracy to cause an explosion.
Two of the nine arrested - women aged 27 and 42 - have been charged with drugs offences and are expected to appear at the same court next month.
The arrests took place in Larne, Lisburn, Armagh, Banbridge and Craigavon.
Detectives also searched properties in counties Antrim, Armagh and Down on Tuesday morning.


A defensive mucus secreted by slugs has inspired a new kind of adhesive that could transform medicine, say scientists.

The "bio-glue" is incredibly strong, moves with the body and crucially, sticks to wet surfaces.
The team at Harvard University have even used it to seal a hole in a pig's heart.
Experts have described the glue as "really cool" and said there would be "absolutely huge demand" for it.
Getting something to stick to a damp surface has been a huge challenge - think what happens when you get a plaster on your finger wet.
The university's Wyss Institute for Biologically Inspired Engineering turned to the "Dusky Arion" slug, which creates sticky mucus as a defence against predators.
"We engineered our material to take on the key features of slug mucus and the result is really positive," researcher Dr Jianyu Li said.
The bio-glue they produced has two components - the actual adhesive and a biochemical "shock absorber".
The incredible stickiness comes from the trinity of the attraction between the positively charged glue and negatively charged cells in the body; covalent bonds between atoms in the cell surface and the glue, and the way the glue physically penetrates tissue surfaces.
But it is the shock-absorbing component that is crucial - it takes the physical stress and strain, so the adhesive component stays stuck.
Experiments, published in the journal Science, show the glue is not toxic to living tissue and is three times stronger than any other medical adhesive.
Dr Li told the BBC News website: "I'm really amazed by this system. We have solved a big challenge and opened up big opportunities in the medical setting.
"The applications are pretty broad - the material is very tough, stretchy and compliant, which is very useful when you want to interface with a dynamic tissue like the heart or lungs."
It could be used as a patch on the skin or as a liquid injected into wounds deeper in the body.
There are also ideas about using it as a way of releasing drugs to specific parts of the body or to stick medical devices to organs like those to help the heart beat.
The glue adheres to a surface within three minutes, but then gets stronger. Within half an hour it is as strong as the body's own cartilage.
Dr Chris Holland, from the department of materials science and engineering at the University of Sheffield, said: "It's really cool, I must admit.
"It is clear it outperforms the alternatives on the market and oh my goodness, there is potentially absolutely huge demand.
"They are still at an early stage, but this kind of thing could be part of a surgeon's standard kit."
But there is not yet a technology ready for medical use.
So far it has proven its capabilities mechanically in the laboratory, in tests on rats and by sealing a hole in a pig's heart through tens of thousands of simulated heartbeats.
The Wyss Institute, which has applied for a patent, says the glue is cheap to make.
It is also working on biodegradable versions that would naturally disappear as the body heals.
Prof John Hunt, the research theme lead for medical technologies and advanced materials at Nottingham Trent University, told the BBC: "The need for new adhesives as glues or tapes is clear to all healthcare providers.
"This one has the potential to improve healthcare and save lives.
"This research is really exciting [but] the detail of the biocompatibility will need to go beyond what is presented in the paper to guide the long-term clinical efficacy, safety, and therefore the real medical applications."

Theresa May came to Glasgow with a clear message for Nicola Sturgeon and the SNP - stop obsessing about independence and concentrate instead on governing Scotland.

She accused the SNP of "tunnel vision" about the constitution. Saying "the SNP play politics as if it is a game" and accusing them of neglecting devolved public services like schools.
It is not hard to see why the Prime Minster wants to stop the talk of another referendum on Scottish independence.
The last thing she needs is to be fighting another referendum campaign whilst also trying to negotiate the UK's exit from the EU. Even though the assembled Conservatives at the conference here today insist they would easily win another referendum.
The Prime Minister knows she could easily prevent another referendum by simply refusing to allow it.
The Scottish government has to ask the UK government to devolve the power to hold another vote before it can go ahead. That's how it worked in 2014 and how it would have to work again.
Mrs May won't currently answer questions about whether she would block indyref2, as it will inevitably come to be known.
At the moment she says she will not answer hypothetical questions. But it's possible that fairly soon this may be a very real dilemma.
She says there is no need for another vote, but she knows that if she refused to allow a referendum that could provoke a constitutional crisis that could generate support for independence amongst Scottish voters.
Nicola Sturgeon says there is another way the PM could avoid indyref2. She could agree to the Scottish government's proposals that advocate Scotland remaining in the EU single market.
But nothing that Theresa May said today suggests she will agree to to that.
UK government ministers say that everyone is eager to secure the greatest possible access to the single market but that there will be no separate, bespoke deal for Scotland.
So will there be another indyref? Very possibly.
With all the talk of another vote being "very likely" and "all but inevitable", Nicola Sturgeon has already marched her troops so far up the hill it's hard to see how she can march them back down again without massive loss of face and political capital.
Today we got an extensive preview of the unionist case.
Mrs May talked at length about the benefits being part of the United Kingdom has bestowed on Scotland and the rest of the UK. And warned of the economic dangers of independence.
It was a serious and substantial speech about why she believes the UK is "Better Together".
If there is to be another referendum you can expect to hear these arguments repeated again and again. This may have been a dress rehearsal for the campaign to come.


An extra 20% tax on sugary drinks should be introduced to tackle the obesity crisis, the British Medical Association says.

It estimates poor diets are causing around 70,000 premature deaths each year.
In a major report on unhealthy diets, the body called for the extra money raised to be used to subsidise fresh fruit and vegetables.
The Food and Drink Federation said the measure would not change diets.
There has been growing concern about the damaging impact of sugar on health - from the state of people's teeth to type 2 diabetes and obesity.
In its Food for Thought report, the BMA warns that a 330ml can of pop is likely to contain up to nine teaspoons of sugar that are simply "empty calories".
The report said taxing specific food groups - such as the sugar drinks tax introduced in Mexico - were shown to cut consumption.
Doctors said a tax of at least 20% would be needed to deter customers.  It would mean a 65p can of fizzy drink would cost at least 78p and a two-litre bottle would shoot up from Â£1.85 to Â£2.22.
The report says the extra revenue should be used to make fruit and vegetables cheaper so that we "create an environment where dietary choices default to healthy options".
Dr Shree Datta, from the British Medical Association, told the BBC: "I think it is a massive problem illustrated by the fact obesity is creeping up.
"We're looking at 30% of the UK population being obese by the year 2030, a large extent of that is due to the amount of sugar we're actually consuming without realising.
"The biggest problem is a lot of us are unaware of the amount of sugar we are consuming on a day-to-day basis."
The government's main approach to obesity has to been to work with the food industry to get it to voluntarily reduce calorie content.
A spokeswoman said obesity was of "great concern to this government".
She added: "There is no silver bullet but we do want to see industry go further to cut the amount of sugar in food and drinks so that people can make healthier choices."
The BMA's report is timely. Later this week, the UK's official Scientific Advisory Committee on Nutrition will publish its final advice on the amount of sugar we should be eating.
Its draft report said sugar added to food or naturally present in fruit juice and honey should account for 5% of energy intake.
The current recommended level is 10% and many people fail to meet that.
Ian Wright, director-general of the Food and Drink Federation, said: "We share the BMA's concerns about the health of young people in the UK."
However, it said many foods were already taxed at 20% through VAT such as soft drinks and confectionery.
He added: "Where additional taxes have been introduced they've not proven effective at driving long-term, lasting change to diets.
"In recent years, calories in household foods and drinks have been gradually lowered through recipe reformulations, including sugar reductions, and changes to portion sizes."


Thousands of Post Office workers will strike next week in a dispute over branch closures, job losses and pensions, trade union officials said.

The Communication Workers Union (CWU) warned the 24-hour strike on 15 September could be followed by more industrial action.
The workers will be joined by more than 700 Post Office managers who are members of the Unite trade union.
The Post Office said it would act to minimise disruption.
Dave Ward, general secretary of the CWU, said: "The Post Office is relentlessly pursuing a programme of cuts that will mean a further 2,000 job losses, staff being left tens of thousands of pounds worse off in retirement and the privatisation of its flagship branches.
"The Post Office is at crisis point and the government has to step in."
The Post Office said it was "disappointed by the call for industrial action", but said that contingency plans would minimise disruption to services during the strike.
Kevin Gilliland, Post Office's network and sales director, said 97% of its 11,600 branches would operate as normal.
"We will also work hard to minimise any disruption to customers in our 300 Crown branches should they be affected by strike action," he said.
The CWU has about 3,500 members working for the Post Office, including counter staff at the 300 Crown branches.
It also has members who deliver cash to rural branches and said it was confident the strike would therefore affect the majority of the Post Office's branches.
"We are making a simple demand," said Mr Ward.
"The government needs to pause the cuts, convene a summit of key stakeholders in the industry and work out a strategy that gives employees and the public confidence that the Post Office has a future."
Mr Gilliland said: "The changes are needed to make our services better for customers and ensure that Post Office branches thrive at the heart of communities for future generations.
"We halved our losses in 2015/16 and are making steady progress to reduce costs to the taxpayer by making our business simpler to run and modernising our network, which is now at its most stable for decades."
A Department for Business spokesman said the Post Office's financial performance continued to improve and the network now had more than 11,500 branches, with 3,500 open on Sundays.


Australian, Canadian and US warships are helping with evacuations and supplying aid to the New Zealand town of Kaikoura after a series of tremors.

About 600 people were evacuated on Wednesday by air and sea.
Workers also established emergency road access to the town, which has been cut off by landslides.
Two people were killed when a severe earthquake hit the area shortly after midnight on Monday, followed by thousands of aftershocks.
An estimated 1,200 tourists were staying in Kaikoura, a popular whale-watching destination, at the time. About 3,500 people live in the town and surrounding area.
The country has been hit by at least 1,823 earthquakes since the magnitude 7.8 earthquake on Monday, according to GeoNet, New Zealand's government-funded earthquake monitoring service.
Engineering consulting firm Tonkin and Taylor, which has been employed by the New Zealand government to assess damage to Kaikoura, told the BBC that the damage in the area was "catastrophic".
"There have been 100,000 landslides, over 50 covering State Highway 1," the main road which runs the length of the country, it said.
But the company said damage to residential housing was "not too bad".
Helicopters began airlifting people from Kaikoura on Tuesday after road and rail links to the town were severed. Power and water supplies have also been disrupted.
An inland road open only to military vehicles transporting aid was established on Wednesday.
New Zealand's warship HMNZS Canterbury helped to transport the majority of Wednesday's evacuees. Another ship, HMNZS Wellington, has been surveying the seabed.
Canada's HMC Vancouver, Australia's HMAS Darwin and the US destroyer USS Sampson are bringing aid supplies and equipment to the town and are due to arrive on Thursday.
The USS Sampson is the first US warship to visit New Zealand in 30 years.
The foreign warships had been destined for Auckland to take part in 75th anniversary celebrations for the New Zealand navy but diverted to help with the recovery effort.
New Zealand Defence Minister Gerry Brownlee said the offer of assistance was "heartening", and that Japan and Singapore had also offered help.
Meanwhile, the cleanup is continuing in Christchurch and the capital, Wellington. Some streets remain cordoned off while safety checks are carried out.
Some buildings have been evacuated because of "structural concerns", TVNZ reported.
One eight-storey office building in central Wellington is expected to be demolished.
"The building is at significant risk of collapse so currently police and fire are conducting operation to seal off the area," Fire Service regional commander Brendan Nally told commercial radio.
Wellington Mayor Justin Lester said the full extent of damage would become clear later, but that the city had "resilience to cope" and the focus should be on "the worst affected areas".
Geonet initially gave Monday's quake - actually two at the same time - a magnitude of 7.5, but has now raised it to 7.8.
It was the largest tremor in the quake-prone country since 2009, it said, while early assessments of the geological changes indicate it was one of the "most complex earthquakes ever recorded on land".
New Zealand lies on the Ring of Fire, the fault line that circles virtually the entire Pacific Rim bringing frequent quakes and volcanic eruptions.
Christchurch is still recovering from a 2011 earthquake that killed 185 people and destroyed the city centre.


Two women on a charity walk along the Pennine Way had to be rescued after suffering heat exhaustion.

The Border Search and Rescue Unit was called out to help the pair - both in their 50s - on Saturday afternoon.
They were part of a group of 10 but navigational errors meant they were stuck near Windy Gyle on the Scotland-England border for longer than planned.
BSARU was able to rescue the women who were suffering from dehydration and heat exhaustion.
The party had set out from Langleeford to complete their charity walk but ended up staying out longer than anticipated.
With just one map between them, they split up after a disagreement with two descending on the Scottish side of the border and five returning to their start point on the English side.
The two casualties and a friend were left "hunkering down" on the ridge.
BSARU said they were found easily and returned to their hotel where they were checked over by the Scottish Ambulance Service.
After rest and rehydration they were able to return home.
"It was a pretty straight-forward job for us," said  BSARU team-leader Stuart Fuller Shapcott.
"The excellent ground conditions meant that we were able to get a vehicle very close to where it was needed, allowing a very simple evacuation."
However, he said it showed the importance of carrying a map when heading into the hills and also underlined that conditions could be just as dangerous in summer as in winter.
"Heat-injury is a much underestimated hazard, and can be just as lethal as hypothermia," he said.
"The onset can be sudden and symptoms can develop faster.
"When heading into the hills in the summer it is essential that you carry enough water, loose light clothing, a sun-hat and sunblock."
He advised checking weather forecasts in advance and in fine weather to "travel light" but carry a lightweight waterproof and extra layer in case temperatures drop.
"As always, the importance of a map and the necessary navigational skills cannot be overstated," he added.


Oxford Circus Tube station was temporarily closed 113 times in the space of a year because of overcrowding, new figures have shown.

The shutters were brought down on entrances a further 15 times for other reasons, including staffing issues and strikes, in the 12 months to October.
Other major Tube stations Victoria and Waterloo closed five times and once respectively.
Transport for London said it recognised Oxford Circus could get "very busy".
More on this story and other news from London
TfL blamed the situation on modernisation work at neighbouring Tottenham Court Road and Bond Street stations.
A statement said: "As part of this work, the Central Line is not currently stopping at Tottenham Court Road, meaning many customers have diverted to Oxford Circus."

But the closures - amounting to nearly one every three days - during evening rush hours have frustrated shoppers and commuters using the station, which is at the busy junction of Oxford Street and Regent Street.
One Twitter user asked: "When will Transport for London sort out overcrowding at Oxford Circus? Closed almost every day at rush hour."
Following the terrorist attacks in Paris, another tweeted the overcrowding made "everyone jumpy".
Minor closures were not included in the figures, released to BBC London through a Freedom of Information request.
These include times when entrances were closed and stations only used for people to interchange and exit.
TfL said these "partial closures" were "treated as 'business as usual' and usually only recorded locally, if at all".
Oxford Circus is London Underground's busiest station, with nearly 100 million passengers entering or leaving the station in 2014.
Stations are closed in order to "ensure that platforms are safe to use and there are not too many people on them," a TfL spokeswoman added.
Tailor Thomas Church, 25, from West Hampstead, who uses the station every day, said the closures affected surrounding businesses.
He said: "When it closes I have to cancel appointments and that means I lose money. It can cost us thousands of pounds every time.
"What I don't get is that London is the world's favourite city and Oxford Circus is at the heart of it - so why hasn't it been upgraded to cope with demand?"
London Mayor Boris Johnson was forced to defend TfL in response to the figures.
"Oxford Circus is in line, as you know, for a huge improvement and don't forget that is one of the reasons why Crossrail is so vital," he told LBC.
"That Central line, that whole network will be radically relieved by Crossrail when it comes in in a couple of years' time."
A spokesman for watchdog London TravelWatch said the figures showed the "need for continued investment in capacity in the face of ever increasing demand".
A July report from the watchdog recommended improving how interchanges are shown on Tube and rail maps.
It said this could include making it clear where stations are a short walk apart, the interchanges that do not require additional fares and those that require passengers to leave the station.
General Secretary of the Rail, Maritime and Transport Union (RMT) Mick Cash said the underground network was "bursting at the seams".
"RMT is now receiving regular reports from our reps of severe overcrowding on both the tube and the commuter rail services," he said.
"All the indicators are that passenger numbers will continue to surge, cramming more people into a capacity that is already at breaking point.
"At the moment the transport authorities are winging it and that is a recipe for disaster. "
"I think it needs to be pedestrian-only. There's just too many people. People are walking in the roads, I just walked in the road myself. It's a bit of a joke," said Jonny Button.
Isabel Cordwell, who works between Tottenham Court Road and Oxford Circus, said: "It stops me getting home in the evening. It's not at the same time every day so it's quite inconvenient.
"But I'm not sure what can be done to change it - it's just the amount of people trying to get in and out."
Rebecca Koczan said: "It's pretty rubbish. Often I just walk to Green Park because I can't be bothered to wait. When you're coming home from work, you just want to get home and you can't because of what's happening."
"You can't get anywhere, can't get home quick enough and it's quite scary. Lots of people bump into you," said Bukky Bello.
"It's a central place. You have tourists, shoppers, people coming from work, that's probably why."


Aston Villa boss Steve Bruce has warned his team that they must handle the pressure of playing for such a big club better, or risk being "swallowed" into Championship relegation trouble.

Villa's run of seven defeats in eight games in 2017 has left them within seven points of the relegation zone.
"The buck stops with me. It's my responsibility," Bruce told BBC WM.
"But we must roll our sleeves up and get back that pride which has eroded over the last six weeks," he added.
"If we don't, we're going to get swallowed into it and we can't allow that to happen. Am I worried? I think I've got to be worried, given how we're performing at the moment."
Speaking after Tuesday's 3-1 home defeat by play-off hopefuls Barnsley, Villa's fourth straight loss, Bruce admitted: "This is the biggest challenge I've ever had, the best club I've ever had, in 20 years in management and I'm determined to turn it round. Given time, I know for a fact I'll do it.
"We had a positive impact when we first came in three or four months ago but that seems to have eroded. We've had a horrible six or seven weeks.
"After some of the horror shows we're seeing at the moment, we have to question the team individually and collectively."
"There were signs of recovery when we first came in," said the 56-year-old. "We had one of the best defensive records but that has eroded with too many silly mistakes, which we simply have to cut out.
"And we can't score, no matter what formation we play. Thirty attempts, 22 on Saturday, and we've scored once. Barnsley have had six and scored three. Jonathan Kodjia has scored again but nobody else does.
"We've got one of the biggest wage bills in the Championship because we're expected to handle playing under pressure and, at the minute, we're not handling it.
"That's what it is to play for a big club. That's why the players who came in January were so determined to come.
"Maybe I've put five or six in too quickly, which really was out of necessity, but it's been difficult for the new ones walking in when confidence is low.
"And we've had a couple of players injured who we haven't had over the last month (Mile Jedinak and Gabby Agbonlahor). But, if we're just going to throw in the towel, that's not me.
"There's been accusations at myself that I'm not bothered, but that couldn't be further from the truth."
One anguished caller to BBC WM's pre-match phone-in on Tuesday asked: "If even Steve Bruce can't put it right, I can't imagine who can."
But Bruce acknowledges just how much the players need Villa's suffering fans to stay on their side over the closing weeks of the season.
"On the whole, the crowd were fantastic," he said. "From what's gone on and what they've just witnessed, they're well within their rights to voice their concerns. It's not easy for them. It's not easy for any of us. But they stayed with us."
For a side such as Villa, who were in the Premier League from its formation in 1992 until relegation in May 2016, the idea of playing in League One seems unthinkable.
But the founder members of the Football League have been down this route once before - they were relegated to Division Three in 1970, before winning promotion under Vic Crowe at the second attempt in 1972.
Were they to fall that far, Villa would not even be England's first former European Cup winners to play in the third tier, Nottingham Forest having sunk that low for three seasons between 2005 and 2008.
There are also enough recent examples of other high-profile clubs to know that it can become reality, and also that those clubs can recover from dark times:


Calls are growing for a man who tried to save MP Jo Cox to be officially honoured for his bravery.

Bernard Kenny, 77, was stabbed in the stomach as he went to the aid of Mrs Cox when she was shot and stabbed in Birstall, West Yorkshire, on Thursday.
Mr Kenny, who was discharged from hospital earlier, called her death "a very sad loss for the community".
An online fund in memory of the murdered Labour MP passed the Â£1m mark on Monday evening.
Thomas Mair, 52, has been charged with the murder of the 41-year-old MP for Batley and Spen.
A petition to Cabinet Office minister Matthew Hancock describes Mr Kenny as a hero who deserves the "highest honour".
It passed its initial target of 4,000 backers earlier on Monday and has now reached more than 17,000.
Meanwhile more than 30,000 people have contributed to the fund set up in memory of Mrs Cox, which will aid three charities.
Her husband Brendan tweeted: "Thank you to everyone for your incredible generosity. This will change lives in Syria, Batley and across the UK."
The George Cross is the highest bravery honour that can be given to non-military personnel.
Mr Mair, who appeared via videolink at the Old Bailey on Monday, is charged with murder, grievous bodily harm, possession of a firearm with intent to commit an indictable offence and possession of an offensive weapon.
Mr Kenny is understood to be a former miner who was part of the rescue operation during a 1973 Yorkshire mining disaster.
Seven men died when part of the now-closed Lofthouse Colliery, near Leeds, flooded.
The petition calls on the Home Office "to award the George Cross to hero who fought attacker of Jo Cox MP".
It adds: "We believe that Bernard Kenny deserves the highest honour for bravery that this country can award."
Eddie Downes, a mining historian and engineer, said: "He's a rescue man, they put their lives on the line whenever they went into a mine, they're a breed apart."
He described Mr Kenny's actions as "superb", adding "not a lot of people would have done that."
After leaving hospital, Mr Kenny and his family issued a statement in which they expressed their sincere condolences to the family of Mrs Cox.
It said: "We would also like to thank people at the scene, the police, ambulance service and the staff at LGI who were excellent in dealing with the situation.
"Finally, many people have shown great kindness over the last few days; this has been much appreciated by the whole family, but now we hope you will respect the fact that we need time and privacy for Bernard to recover."
Mr Kenny's actions were remembered at a church service at St Peter's Church in Birstall on Sunday.
Parishioner Leif Wickes said that "despite his 77 years" Mr Kenny "intervened in the attack to try to save Jo's life and was stabbed and badly injured".
He added: "We give thanks for his courage and his example and pray for his speedy recovery."
MPs, who had been in recess for the EU referendum, have been recalled to the Commons to remember Mrs Cox.


There were nine attempts to use drones to infiltrate prisons in England and Wales in the first five months of 2015, according to the Ministry of Justice.

Among them was a drone carrying mobile phones and drugs that was intercepted by guards at Bedford Prison in March.
The use of drones is an "emerging threat", Eve Richard from the National Offender Management Service told a defence and security conference in London, the Independent reported.
Attempts are rare, the government said.
There were four known attempts to fly drones into prisons in England and Wales in 2014, the MoJ confirmed.
In August, a drone was found in the grounds of Norwich prison, while another was found caught in fencing at Liverpool prison recently.
Even the highest security prisons are vulnerable to unmanned aerial vehicles (UAVs), the Independent quoted intelligence analyst Ms Richard as saying.
There is no evidence that drones have been used to successfully smuggle contraband items into prisons, but there is potential for it to happen in the future, she reportedly told a briefing at the Defence and Security Equipment International exhibition in London.
"In a nutshell, our intelligence suggests that the use of UAVs to release items into our prisons is an emerging threat. It's not a huge issue at the moment but there is the potential for it to increase and become more of an issue," the newspaper quoted her as saying.
Mark Icke, vice-president of the Prison Governors Association, said he believed the drones were mostly being used to try to smuggle drugs into prisons.
"What we've got happening in the prison system at the moment is that we have younger, more advanced criminal networks operating in and around prison systems," he said.
"We're talking about big, organised gangs, and they're not about disorder, they're about making money. There is a huge mark-up on drugs in prison."
He said the use of drones was "an emerging threat and something we're concerned about", but that prison guards had limited control over preventing them.
Security caging around windows and overhead netting in prison yards, similar to that used in high security prisons, would help reduce the threat, he said.
The Prison Service said incidents involving drones were rare, but it remained "constantly vigilant" to all new threats.
A spokesman said: "We are introducing new legislation to further strengthen our powers, making it illegal to land a drone in prison or to use a drone to drop in psychoactive substances.
"We take a zero-tolerance approach to illicit material in prisons and work closely with the police and CPS to ensure those caught are prosecuted and face extra time behind bars."
Anyone using drones in an attempt to get contraband into prisons could be punished with a sentence of up to two years, he added.


Manchester United became the first club to lift the FA Youth Cup 10 times after beating Sheffield United 4-1 to seal a 6-3 final win on aggregate.

A day after their senior side collected the league trophy for a record 19th time with highly rated Ravel Morrison and Will Keane each scoring twice.
Sir Alex Ferguson was in the stands to witness the historic triumph against a talented group of young Blades players.
They pegged United back twice in the first leg but were outplayed on Monday.
Sheffield-born Jordan Slew, who has already made eight first-team appearances and has a couple of England under-19 caps to his name, impressed for the visitors.
He went close on a couple of occasions before the break, including a dipping shot that had Sam Johnstone scrambling across his goal to watch it to safety.
For Manchester United - for whom Sir Matt Busby's 'Babes' won the Youth Cup five years on the trot from 1953 - French import Paul Pogba, Ryan Tunnicliffe, Morrison and Keane all shone brightly.
But Morrison was the key player - securing his brace through a smart piece of control and finish in the first half and a run and low shot from 20 yards in the second.
With Keane scoring from the spot and adding his own second, United were ultimately comfortable winners, rendering Joe Ironside's strike for the Blades nothing more than a consolation.


Mockingjay Part 2, the final Hunger Games film, has topped the UK box office on its opening weekend, taking £11.26m.

Jennifer Lawrence's fourth outing as Katniss Everdeen ended James Bond's three week chart-topping run.
Spectre, starring Daniel Craig as Bond, took £3.82m, above The Lady in the Van in third spot with £1.61m.
Animated sequel Hotel Transylvania 2 was in fourth, while Brooklyn, starring Saoirse Ronan, was in fifth.
The latest instalment of The Hunger Games franchise took less at the box office than its predecessor.
Mockingjay Part 1 made £12.6m in the UK in its opening weekend, accounting for two out of every three tickets sold, its distributor Lionsgate said.
The first Hunger Games film, based on Suzanne Collins' book, took a total of £24m in the UK, and nearly $700m (£433m) worldwide.
Despite dropping to second spot in this week's chart, Spectre has overtaken Titanic to become the third highest grossing film in UK box office history, according to Rentrak.
The latest Bond film has taken a total of £84.31m to break into the all-time top three, behind Avatar with £94m and Skyfall with £103m.


Russian ballet legend Maya Plisetskaya has died in Germany aged 89, the director of the Bolshoi Theatre says.

Vladimir Urin says she died of a heart attack. "The doctors tried everything, but there was nothing they could do," he is quoted as saying by Tass agency.
Russian President Vladimir Putin expressed his "deep condolences" to Plisetskaya's family and relatives.
Plisetskaya joined the Bolshoi in 1943, captivating audiences around the world with the purity of her performances.
In 1960, she became the Bolshoi's prima ballerina.
Among her acclaimed roles were Odette-Odile in Swan Lake, Aurora in The Sleeping Beauty and Carmen in Carmen Suite.
Plisetskaya left the stage aged 65, becoming a choreographer and giving master classes around the world.
She moved to the German city of Munich with her composer husband Rodion Shchedrin in 1991.


Almost 150 people have waited more than 12 hours on trolleys at Royal Stoke University Hospital in the last week.

A major incident declared at the hospital on Monday remains in force.
A meeting of the North Staffordshire Clinical Commissioning Group (CCG) heard almost all planned surgery had been cancelled.
The hospital said as well as increased demand at A&E, it had struggled to free up beds due to an outbreak of norovirus and flu.
Sally Parkin, clinical director at the CCG, said: "There are 91 cases of flu at the moment in the hospital and we have to keep patients safe, so we have to have areas that are separately nursed for patients with infections illnesses
"So at the moment we just don't have enough bed capacity for those patients and that's why we've got a bottleneck in A&E."
She said while the Royal Stoke A&E  was "very busy", patients were being cared for and dealt with in a "calm and systematic way".
Last week, the University Hospitals of the North Midlands trust, which runs the Stoke Royal recorded the worst A&E figures in England, with just 61.3% of patients seen within four hours, compared with a national target of 95%.


The new first minister has rejected the idea of God Save the Queen being dropped as the anthem of the Northern Ireland football team.

Arlene Foster said she does not want the issue to be "politicised".
Stormont authorities have rejected an attempt by the Irish Football Association (IFA) to place responsibility for the issue with the assembly.
An IFA spokesman said  it was "a matter for the politicians".
However, a spokesperson for the Office of the First and Deputy First Minister told the BBC that "the playing of a national anthem, or any song at football matches, is a matter for the organisation involved."
Renewed calls for a fresh anthem in Northern Ireland follow initial support by MPs to the idea of the England team adopting an official national anthem.
God Save the Queen, the national anthem for the UK as a whole, is currently used for England during most sporting events.
However, Chesterfield MP Toby Perkins believes England needs its own anthem and presented his case in the House of Commons as a 10 minute rule motion.
His English National Anthem Bill was adopted by the House.
The Scotland and Wales football teams have their own anthems but like England, Northern Ireland uses God Save the Queen.
However, when Northern Ireland athletes compete in the Commonwealth Games, the song Danny Boy is used.
Arlene Foster, who became first minister on Monday, rejects the idea of change for football.
She told BBC One programme The View: "We have a national anthem, as you know, but I'm also very conscious that we don't want to get into the politicisation of sport because sport is something that unites people. Right across Northern Ireland people are getting behind our sporting heroes.
"We have a national anthem. I don't think there's any need to tinker with that, but it's something we're all looking forward to into the summer and the sporting exploits of our heroes.
"I don't see any reason to change it. I understand the 10 minute rule bill is in relation to the English football team in any event and its not really in relation to the Northern Ireland football team, but as I say I don't want to get into politicising sport because it's something that unites everybody."
When asked for its view, Sinn FÃ©in said that it supports the idea of an all-Ireland team.
The west Belfast MLA, Pat Sheehan, said: "On its own, it's not going to make a massive amount of difference [changing the anthem], but there are a range of options that the IFA could put in place, that would make Windsor Park a more welcoming sports stadium for all of the community.
"I feel there is still a chill there [Windsor Park] and I think the playing of God Save the Queen plays into that."
Also speaking on The View, the first minister said she will be using the St Patrick's Day visit to the United States to sell Northern Ireland.
Ms Foster will be accompanied by Deputy First Minister Martin McGuinness for the now traditional engagement at the White House.
She said the visit, in March, is an opportunity to promote the economy.
"I think we should use it to talk about the economy of Northern Ireland and the fact that we are going to lower corporation tax in April 2018, because that gives us a great opportunity to talk about a fresh start," she said.


Pop star Adele has helped a couple enjoy a memorable proposal in front of 77,000 fans at a concert in Australia.

Wade Nicholson-Doyle took his boyfriend, Chris, to the Melbourne show as a 40th birthday present.
When the singer selected the pair from the crowd, Mr Nicholson-Doyle dropped to one knee and proposed. A loud cheer went up around the stadium.
"Did you say yes?" Adele joked, before embracing the couple.
"I actually had no idea that was going to happen. Congratulations."
Mr Nicholson-Doyle said he was momentarily unaware of the screaming crowd.
"It just kind of blacked out and all I could see was Chris and Adele standing there," he told the BBC.
"To share the stage with her, if only for five minutes, is really incredible. We're very much in her debt."
Same-sex marriage is not legal in Australia. A proposal for a vote on the issue was blocked in parliament last year.
However, Mr Nicholson-Doyle said they would hold a celebration with friends and family in Australia.
"We've made no plans yet," he said.
"I think Chris's head is still spinning at the moment."


Torquay United manager Kevin Nicholson is unsure about his future following the takeover of the club.

Swindon-based Gaming International (GI) agreed a deal on Friday, which they hope will go through early this week.
"I don't know what their plans are with the club," Nicholson told BBC Devon.
"They're the new owners of the club, so they are in a position where whatever they choose to do with me, with the club and everything else they're well within their rights to do it."
Nicholson is due to meet the new owners on Monday to hear more about their plans for the Gulls, who were relegated from the Football League in 2014.
"Until I've sat and had a chat with them and heard what they've had to say, and I get a chance to put my side of it over and explain to them where I think we need to improve and what we need to do, then there's not much I can say," added Nicholson.
"I took the job last year and my targets haven't changed, my targets are to give this club back to the community, to get the club back in the Football League and to be around to see that."
The takeover ended a period of uncertainty surrounding the club, which had been due to pay GI a loan of £125,000 in January.
The company had lent the Torquay board the cash during their initial takeover talks, which broke down in July.


A West Lothian man has been scammed by a bogus customs official who asked him to pay off a "debt" using ITunes vouchers.

The 61-year-old man received a call from a man claiming to be from HM Revenue & Customs on Thursday at 09:00.
The caller told the man he had a Â£500 debt, which would need to be paid immediately.
The man was told to buy the vouchers and give the serial numbers to the caller, which he did.
PC John McLean, of Police Scotland, said: "Often these fraudulent callers sound extremely convincing and authentic but we would urge the public to remain vigilant.
"If they are in any doubt that it's genuine hang up the phone and report matter to HMRC who take scams and bogus callers of any kind very seriously."
An HMRC spokesman said: "HMRC takes security extremely seriously. We are aware that some people have received telephone calls from individuals claiming to be from HMRC.
"We are a well-known brand, which criminal's abuse, to add credibility to their scams. HMRC will never request tax debts to be paid in payment vouchers and we are clear that they cannot be used to pay tax.
"We recommend that if you cannot verify the identity of a caller that you do not speak to them."


Some children are coming to school with cold chips or just a packet of biscuits in their lunchbox, experts say.

An online survey of 250 school, youth and health staff working with children in England suggests many go without enough to eat during the school day.
The Children's Food Trust's poll found 68.1% had seen a rise in the proportion of families struggling to feed their children in the past two years.
Lunchboxes now contain less fruit and more junk food, it suggests.
Of the staff working in schools, 47.5% said they had seen a change in the food in children's lunchboxes as household budgets got tighter.
One staff member said they had seen "poorer quality sandwich fillings, sometimes just margarine".
Another said there were "fewer processed items - more leftovers or store-cupboard items".
But he added: "In some ways it is healthier, but some families only give cold cooked rice or cold chips with fish fingers or similar."
There were also references to more junk food, sweets and chocolate appearing in lunchboxes, and less fruit.
The snapshot survey also found 84.6% of the professionals who chose to take part in the survey had seen children without enough to eat during the course of their work.
Of those who said this, 84.8% said it applied to about a third of the children they worked with.
Children's Food Trust chief executive-designate Linda Cregan said too many people who worked with children were having to go above and beyond the call of duty to try to protect children from the effects of hunger and poor diet.
She added: "Of course it's a parent's responsibility to make sure their child eats well.
"But as this and other surveys have shown, the reality is that this can be an enormous struggle.
"Whether we like it or not, people working in these jobs are at the front line of helping parents on this, so they need the right support.
"As local authorities develop their public health plans, ring-fencing funding to support children's nutrition would be a good starting point.
"This could be used in all sorts of ways -  training on cooking skills for local organisations working with families,  subsidising good school food, breakfast clubs in schools or grub clubs for the holidays - but making that explicit commitment is vital."
Pupils at Priory School in Lewes told the BBC's School Report project their lunches were generally quite good.
"I haven't seen people with chips in their lunchboxes - but the school does do chips on Fridays though. I guess people just get that," said Flora, aged 14.
Ellen, aged 13, agreed that most people were quite healthy: "I take a piece of fruit to school every day."
School dinners were easier, quicker and nicer because "you can get hot food", according to Ossia, 14.
And 13-year-old Safi said: "Packed lunches are cheaper. I can buy in bulk and have the same thing every day."

Glasgow moved up to fifth in the Pro12 as they edged to victory over Newport Gwent Dragons in a high-tempo but error-strewn game.

Duncan Weir grabbed the decisive try in the 73rd minute after a break by Josh Strauss, with the fly-half also kicking eight points.
Alex Dunbar crossed for the only other try just after the interval.
The Dragons were restricted to five penalties from the boot of young fly-half Angus O'Brien.
Glasgow went into the game boosted by the release of six players from the Scotland squad, including Weir, captain Strauss and Rob Harley as starters.
The Rodney Parade pitch had an unusual look about it with tons of sand deposited on the surface to keep it playable.
In the first half O'Brien slotted four penalties against two from Weir, but Glasgow survived the sin-binning of American lock Greg Peterson without conceding.
The Dragons found difficulty in piercing the Warriors' defence once they got into the visitors' 22, while the Scots were bedevilled by handling errors in attacking positions.
But Glasgow came out stronger after the break and Dunbar crashed over following a rolling maul for Weir's conversion to give them the lead on 43 minutes.
O'Brien kicked his fifth penalty to restore a precarious advantage for the Welsh region at 15-13, with both sides missing further shots at goal.
Glasgow's bench was able to give the visitors more momentum and with seven minutes left, Strauss's charge into the home 22 saw Weir snap up the inside ball to score, with video referee Paul Adams judging the pass legitimate.
That was the last score of the game with Weir named man of the match as Dragons had to settle for a consolation bonus point for the sixth time in eight league games.
Newport Gwent Dragons: Carl Meyer, Ashton Hewitt, Adam Hughes, Adam Warren, Nick Scott, Angus O'Brien, Sarel Pretorius; Phil Price, Thomas Rhys Thomas (capt), Brok Harris, Cory Hill, Matthew Screech, Nick Crosswell, Nic Cudd, Lewis Evans.
Replacements: Rhys Buckley, Hugh Gustafson, Lloyd Fairbrother, Rynard Landman, James Benjamin, Charlie Davies, Geraint Rhys Jones, Ross Wardle.
Glasgow: Peter Murchie; Taqele Naiyaravoro, Glenn Bryce, Alex Dunbar, Rory Hughes; Duncan Weir, Mike Blair; Jerry Yanuyanutawa, Fraser Brown, Sila Puafisi, Greg Peterson, Leone Nakarawa, Rob Harley, Simon Favaro, Josh Strauss (capt).

Leon Clarke's 16th goal of the season saw Bury beat Oldham, who extended their winless home run to 13 games.

Bury took the lead early on when Clarke capitalised on James Wilson's inability to deal with Danny Pugh's high ball and fire home from close range.
Oldham keeper Joel Coleman denied Clarke a second, before Andrew Tutte fired a volley just wide.
The home side piled on pressure after the break, but Bury's Ian Lawlor pulled off two smart saves to secure the win.
Oldham manager John Sheridan told BBC Radio Manchester:

"I know they're going to give me effort, but effort's not good enough is it?
"We've got to create opportunities because we've got to score goals to win games.
"It's hard for the supporters, I know it is. We look vulnerable"
Bury manager David Flitcroft told BBC Radio Manchester:

"Extremely proud of a fantastically battling performance.
"It's been difficult on the road over the last month to six weeks.
"It was always going to be a tough game but our fans really diffused that."


Profit jumped at Zara owner Inditex in the first half of the year as the firm opened new stores and invested in online.

The world's biggest clothing retailer posted net earnings of €1.26bn (£1.1bn) in the six months to 31 July - up 8% on the same period last year.
Sales jumped from €9.4bn to €10.5bn, an increase of 11%.
The group's clothes can now be bought online in around 40 countries, it said.
Inditex operates eight brands in 90 countries including Pull&Bear, Massimo Dutti and Bershka.
How Zara's founder became the richest man in the world - for two days
Chairman and chief executive Pablo Isla emphasised the firm's investment in technology, saying the firm had expanded its online stores to 11 new countries in the period.
It also launched mobile phone payment in all its Spanish stores, with the objective of "extending the service to other countries".
This will encompass online apps for all of its brands and a specific app for the whole group called InWallet.
Mr Isla said: "Both our online and bricks-and-mortar stores are seamlessly connected, driven by platforms such as mobile payment, and other technological initiatives that we will continue to develop."
Tom Gadsby, an analyst at Liberum, said the firm's "online drive" was important.
"I expect over the years they may find they don't have to open as many stores to maintain their strong growth rate as the online channel will become increasingly important," he said.
"And while Zara is available in many of the territories in which they operate [online], most of their other brands aren't readily available outside Europe online.
"So there is a big opportunity there for them to expand online into new territories."
The company also said it had benefited from steady economic growth in Spain, where Inditex gets about a fifth of its sales.
That country's clothing market grew at an average of 3% in the three-months to the end of July, according to the Spanish statistics agency.
All of the group's brands increased their international presence during the period, with 83 new stores opened in 38 countries.
In a call with analysts, it said it would open 6-8% of new store space over course of the year.
The firm's strong performance sets it apart from European rivals H&M and Next, which have blamed unseasonal weather for below-forecast results this year.


US parcels delivery firm FedEx has reported a net loss of $895m (£568m) for the three months to the end of May, missing analysts' expectations.

Over the same period last year, the company made a profit of $780m.
The company blamed the strong US dollar and rising pension costs for weighing on its bottom line. These offset a modest rise in domestic package volumes of 2%.
Looking forward, the company said it expects improved results.
"We expect strong earnings growth in fiscal 2016 as we continue to focus on improving performance and successfully executing our profit improvement initiatives," said Alan Graf, FedEx's chief financial officer.
The company said its outlook does not include any costs associated with its purchase of its Dutch package delivery firm, TNT Express.
FedEx announced plans to buy its Dutch rival for €4.4bn ($4.8bn; £3.2bn) in April, as it looks to expand its European operations.
FedEx shares were down more than 3% in early trading in New York.


GCSE results day has finally arrived and many teenagers will be celebrating success, but others will have very different emotions if they do not receive the results they were expecting.

Places on many school sixth form or college courses depend on achieving minimum grades at GCSE - so if your marks did not meet expectations, getting good advice is crucial.
Catherine Sezen of the Association of Colleges is on hand to give advice on what to do following unexpected results.
YOUR QUESTIONS ANSWERED
My son only got three C grades and all the rest  of his GCSEs were Ds. The school he has been attending for the last five years have said that, as he only got three good GCSE's and they require at least five for sixth form, they cannot offer him a place to stay on. Where do we stand as he really wanted to stay there for sixth form? Catherine
Hi Catherine
I am sorry to hear that your son didn't quite achieve the grades that he wanted, but I am sure with there will be a course for him, perhaps at a different school or college.
All schools and colleges have entry requirements which they need to apply consistently to all applicants.
If your son wants to stay at the same school it is worth asking if they have another option for him there. I would also suggest contacting your local FE college to discuss what they might be able to offer. College based vocational or technical courses have good career progression opportunities - or they might suggest an apprenticeship.
If your son is worried about moving to a different school or college it would be good to find out why. All schools and colleges will have induction programmes to help students settle in and make friends.
Catherine
I've missed a large amount of my secondary education (almost 3 years) due to mental health issues and although it was a struggle, I managed to achieve 4 A*s, 1 A, 2 Bs, 1 C and a D. Unfortunately this D was in drama, the subject I want to focus on in college, and although the college didn't need any specific drama grade on entry (only an English grade at C or above and I achieved A*s in both literature and language) I can't help but feel this might affect my chances. Any advice? Kat
Hi Kat,
Well done on your GCSE results. You have done really well to achieve such good grades. The college would be best placed to advise on your drama grade though, if the entry requirements specified English grades (which you have exceeded), I don't think there will be a problem.
Catherine
I've just got my results, I got 3A*s and 8As. I thought I could have done better but they are OK. Do you think I can still get into medicine?
Thanks, Musa
Hi Musa
First of all congratulations on an excellent set of results - well done! Each university will have its own entry requirements for medicine as for all subjects.
I would suggest that your GCSE results would indicate that you have a very realistic opportunity to go on and be successful in your chosen field, but if you have a particular course or university in mind you could look at their entry requirements online to check what they would be looking for.
Good luck with your further studies,
Catherine
I am disappointed with my results. I think exams are unfair because some people are unlucky when they take exams. I received an A for media studies - but because I only got a C in English language I am told I'm not allowed to take it at A-level.
I was also told I could not take psychology, a totally new subject to me, because I have not got Bs in English and maths.
Shouldn't people's work ethic be taken into account more when it comes to what courses they can apply for next and shouldn't coursework be a large part of the courses to make it fairer?
Danny
Hi Danny
Well done on getting the A grade for media studies.  I would see this as an opportunity to think hard about your next steps. Why don't you contact your school and local further education college to see what options are available to you with the grades that you have achieved?
BTEC courses for example include more coursework and still provide excellent opportunities for progression into work or to higher education.
I am sure you will find a course which suits you and your career aspirations.
Catherine
My son received GCSE D grades English and maths but has already started working on an apprenticeship scheme which is full time, five days a week.
I understand that if grade A-C is not achieved in English and maths then it is the law that the child must continue in education until they are 18 to try and achieve grade A*-C. Is this true in all cases such as if they are on an apprenticeship which isn't offering day release?
I am delighted to hear that your son has secured an apprenticeship. If he has achieved Ds in English and maths I think that he will need to continue studying these subjects as part of his apprenticeship. I would suggest that you contact his apprenticeship provider to check whether this will mean retaking GCSE or taking Functional Skills qualifications in English and maths which are more work related.
Catherine
My son is normally an A student bordering on A*. He just received his GCSE results and is heartbroken. He spent many hours studying and he got just one A in maths and Bs in every other subject. His lowest percentage was 72 so why did he fail to get As across the broad?
Hi Leon
First of all congratulations to your son that he has done so well in passing all his GCSEs. I appreciate, however, that he may feel disappointed if he was anticipating higher grades in many of his subjects.
I would suggest in the first instance that you contact his school to get their view on his grades. It may be that they will suggest a re-marking for some of his papers.
However, with the grades that he has got, your son should be able to get on to the course of his choice at school or college.
I wish him well in his future studies.
Catherine
My son did not get the required grade A in his AQA biology - he got a B. What are his options with this result? I am not sure what to do really.
Lynd
Hi Lynd,
It sounds as if your son may well have achieved the grades he needed in his other subjects, which is great and congratulations to him.
I would suggest contacting the school to discuss his biology grade. If he was close to the required A grade you could ask for a review of marking for that subject.
The school may also consider allowing him to take the A-level and monitor his progress over the first few weeks. However, do bear in mind that there may be other young people in the same situation and the school will need to be consistent in their approach.
Catherine
My son has achieved grade C in GCSE science. His mark equivalent is 273. He got 87A in practical and in the papers he got 98C and 88C.
I want to know please where a grade B will start from as he was predicted a B and I'm wondering whether to appeal this result if it's really close to a B grade.
Nasima
Hi Nasima
I would suggest contacting his school to ask whether they think a review of results would be a good idea.  They will have an overview of his results and his work throughout the year and would be best placed to advise on a re-mark.
Good luck to your son in his future plans.
Catherine


Champions Rangers' slump in form continued thanks to Livingston defender Craig Halkett's first-half header against his former club.

Media playback is not supported on this device
Rangers, who have already clinched the Championship title and promotion, have now gone three games without a victory.
Halkett's first goal of the season - the final piece of action in the first half - won the points.
And it will give second-bottom Livi renewed hope that they can avoid relegation via the play-offs.
This was only the fifth defeat of Rangers' league season, but Mark Warburton's side have now not won since beating Celtic in the Scottish Cup semi-final.
Livingston had gone into the game with only 17 fit players and gave a first start to 16-year-old Matthew Knox.
The highly talented midfielder has actually been training with Rangers, who had a bid in the region of £100,000 rejected for his services.
Knox is also interesting Chelsea, Everton, Manchester United and Tottenham Hotspur.
The fact that virtually the length of the division lies between the teams was underlined by the early possession and pressure.
It was all Rangers from the first whistle and Andy Halliday, Gedion Zelalem and Michael O'Halloran all had opportunities to score.
Incredibly, though, it should have been Livingston taking the lead. Zelalem lost the ball in his own half and Danny Mullen suddenly found himself clear, but the midfielder shot wide.
The warning bells were ringing for the division's champions when Sam Stanton also had a dancing run and a shot past the goalkeeper's left port.
The half did, indeed, come to a remarkable finish. In its dying seconds, young Knox whipped in a fabulous free-kick from the left and Halkett met it with the perfect header to flash the ball beyond diving goalkeeper Wes Foderingham.
Rangers supporters in the crowd of 5,021 looked like they could hardly believe the scoreline.
The second half picked up on the first half script. The Ibrox side continued to huff and puff and fluff chances.
Livingston grew in confidence as the league's champions produced one of their poorest showings of the term.
The West Lothian side should have had a second goal, but Liam Buchanan put the simplest of headers over the bar from inside the six-yard box.
The same player, one on one with Foderingham, was only denied by a block from the the goalkeeper.
Livingston were worthy winners. Rangers looked a shadow of the team that grabbed the Old Firm headlines and are preparing for the cup final against Hibernian.


Chad's President Idriss Deby has announced he will run for a fifth term in April's elections.

Mr Deby took power in a coup in 1990 and later introduced elections.
A referendum in 2005 scrapped a clause restricting presidents to two terms, but Mr Deby said that if he gets re-elected he will reinstate it.
In the last year, Burundi, Rwanda and Congo-Brazzaville have all changed their constitutions to allow their presidents to run for office again.
Africa Live: BBC news updates
Mr Deby said on Tuesday that reinstating term limits would provide "vitality" to the democracy.
"We must limit terms, we must not concentrate on a system in which a change in power becomes difficult," he told the ruling party.
"In 2005 the constitutional reform was conducted in a context where the life of the nation was in danger," he added.

Uggie, the dog who shot to fame in 2011 Oscar-winning film The Artist, has been put to sleep at the age of 13.

The Jack Russell was put down after suffering from a prostate tumour.
Uggie played Jean Dujardin's dog in The Artist and also appeared with Robert Pattinson in 2011's Water for Elephants.
Uggie's owner Omar Von Muller wrote on Facebook: "We regret to inform to all our friends, family and Uggie's fans that our beloved boy has passed away."
He added: "Uggie had a cancerous tumour in the prostate and is now in a better place not feeling pain."
The talented terrier "retired" in 2012 but went on to make sporadic TV appearances.
The dog's most recent credit, according to movie site IMDB, was 2013 TV movie Holiday Road Trip, in which he played a dog called Scoots.
Uggie won the tongue-in-cheek Palm Dog award for best canine actor at the 2011 Cannes Film Festival, and was the first dog to leave his paw prints on cement outside Grauman's Chinese Theatre in Hollywood.
The organisers of the Palm Dog prize have paid tribute to the much-loved mutt, calling him "a special little Jack Russell who gave pleasure to millions".
Uggie also published an autobiography, ghost-written by Wendy Holden.


Geraint Thomas secured his second medal of the Commonwealth Games with a stunning gold in a gruelling men's road race on the final day in Glasgow.

Thomas, who won bronze in the time trial, survived suffering a puncture with just 6km to go to finish in a time of four hours 13 minutes and five seconds.
"It's unbelievable really, I never expected it to be honest," he said.
Thomas revealed he will be Wales' flag bearer at the closing ceremony.
"Darren [Tudor] our coach told me this morning just before the start that Wales wanted me to carry the flag," Thomas added.

Thomas's win secured Wales' fifth gold of the Games in a total of 36  medals - nine more than the pre-Games target.
Team-mate Luke Rowe was sixth, Scott Davies finished 10th while Owain Doull, Sam Harrison and Jon Mould were forced to pull out of a race in which pouring rain made conditions difficult.
Earlier in the women's road race, Amy Roberts finished 14th and was one of the leaders until the fifth lap, when she became part of the chasing pack
Elinor Barker, a silver and bronze medal winner on the track during the Games, retired from the race.
Hayley Jones, 18, crashed out of the women's race at the end of the third lap and 25-year-old Katie Curtis crashed out in the fourth lap.
Wales began the final day in Glasgow with 35 medals, eight more than the pre-Games target of 27.
At the closing ceremony rhythmic gymnast Frankie Jones was awarded the David Dixon Award.
It is given to the outstanding athlete of each Games based on their performance, fair play and overall contribution to their team.
Jones, 23, won six of Wales' medals at Glasgow, including their first gold of the Games, in her last performance before retiring.


A taskforce to tackle "economic challenges" in the south Wales valleys has been set up by the Welsh government.

Lifelong learning minister Alun Davies told AMs the focus of the group would be employment and economic issues.
He said valleys communities were "dispirited and under-engaged" and it was time to listen and act on people's "real world circumstances".
Chairman Mr Davies said it would be "active and not a bureaucratic quango".
Plaid Cymru's Bethan Jenkins welcomed the move but said the outcomes of the taskforce had to be measured by an independent group and not the Welsh Government "otherwise it will be like marking your own work".
Conservative Mohammad Asghar said the chairman of the body should be independent of government and said communities should be properly consulted about its work.
Mr Davies said communities would be consulted.


Nobody is to be charged over the death of a 21-year-old man found with serious head injuries in Derbyshire a year ago.

The body of Halcyon Theuri, 21, from Oakerthorpe, was found in the early hours of 31 August 2015, on Wingfield Road, Alfreton.
An inquest into how he died will be held at a later date. Derbyshire Police said there was "insufficient" evidence to charge anyone.
Two arrests were made, but police now say the investigation is "complete".
The two were arrested in September 2015 on suspicion of causing death by dangerous driving. Both were later released on bail.
Despite several appeals to the public , Derbyshire police said: "The investigation into the death of Halcyon is complete. There was insufficient evidence to bring charges."
A spokeswoman added if further evidence did come to light, "it would be looked at and [the case] potentially reopened."
Speaking after his death, Mr Theuri's mother Faith and stepfather Andi, said: "Halcyon was a caring and loving grandson, nephew, brother, friend to many and son to us.
"The void that has entered our lives is not anything we would wish on any parents."


The biggest film awards in the world, the Oscars, produced some big British winners and top prizes for kids films too in Los Angeles, USA, on Sunday night.

Inside Out won the Oscar for best animated film beating Anomalisa, Boy and the World, Shaun the Sheep Movie and When Marnie Was There.
British actor Mark Rylance won the best supporting actor Oscar for his role in Bridge of Spies, with fellow Briton Sam Smith winning best original song.
Spotlight took home the best picture Oscar with Mad Max: Fury Road picking up the most awards of the night, with six prizes.
This year's Oscars ceremony had been criticised by some Hollywood actors protesting about the lack of diversity among this year's nominees, as all 20 nominees in the best acting or supporting acting categories are white.


Home loans advanced to UK buy-to-let investors in November leapt 35% from a year earlier, ahead of key tax changes.

The Council of Mortgage Lenders (CML) said the rise took the number of buy-to-let loans to 23,300, although this was down 6% compared with October.
Landlords in England and Wales will have to pay a 3% surcharge on each stamp duty band from April.
In addition, changes being brought in over the next few years will alter tax breaks available to landlords.
"Landlords may be disgruntled by the double whammy of tax changes and the impending hike on stamp duty, but they can't complain about some of the cheapest buy-to-let rates ever," said Mark Harris, chief executive of mortgage broker SPF Private Clients
"Many landlords are taking advantage of low rates and the removal of tax breaks with remortgaging accounting for the majority of activity in the sector.
"However, lenders are imposing tighter criteria on buy-to-let mortgages when it comes to stress testing, and others are expected to follow, making it harder to qualify for higher loan-to-value mortgages, particularly in the south [of England] where yields are low."
The value of loans advanced in the buy-to-let sector increased by 46% in November compared with the same month a year earlier, to Â£3.5bn.
In the UK mortgage market as a whole, the number of home loans advanced for house purchases was 9.3% higher than the same month a year ago, and the CML is expecting a steady rise in mortgage lending over the next two years.
A total of 60,100 mortgages were advanced in November, although this was down 9.2% from October.
The CML said that the seasonal dip was "normal".
"Mortgage lending activity eased back as the normal dip in the winter months began," said Paul Smee, director general of the CML.
"There was still growth across all lending types in November compared to the year earlier suggesting continued improvement. Our forecasts anticipate that gross lending will continue a slow but steady upward trajectory over the next two years."
