The Austrian authorities have ordered a post-mortem examination following the death of a Nottingham teacher on a skiing trip.
Jonathan Taylor, aged 44, fell to his death in the early hours of Easter Sunday as he walked with colleagues.
The school has ended the trip early with pupils aged between 14 and 15 expected to return to the UK this evening.
The Foreign Office confirmed the death of a British national in Austria.
A spokesman said the next of kin had been informed and it was providing consular assistance.
Austrian Police say Jonathan Taylor the Nottingham IT teacher who died after falling on a skiing trip was the last person in a group of his colleagues making their way back but for some "unknown reason" fell.
The 44-year-old went down a steep slope and then fell 13ft off of a high stone wall onto the road below.
Police say the fall left the teacher with "serious head injuries". Emergency services attempted to resuscitate Mr Taylor but he died at the scene.
The Chair of Governors at Christ The King Voluntary Academy Roman Catholic school in Nottingham, David Wilson, said:
"Jonathan Taylor joined Christ the King last Easter. He was a valued member of the school and was popular with both pupils and staff. This is a very sad loss and our thoughts and prayers go out to his family."
Work and Pensions Secretary Iain Duncan Smith has said that housing benefit changes that have been introduced today are about "fairness".
In response to criticisms of the so-called 'bedroom tax', he said: "The reality is this is about getting our housing benefit back into order".
"This is about fairness. It's about fairness to those who pay vast sums of money in taxation to see that people living in subsidised accommodation who often don't use the bedrooms they've got, while others in overcrowded accommodation.... they can't get the accommodation they need.
"This is a nonsense problem that was created by the last government who didn't build enough housing and didn't manage the housing stock properly".
Around 100 people gathered in Nottingham today to protest against the government's 'bedroom tax' which it is claimed will affect thousands of households.
Dubbed by Labour as the 'bedroom tax', it will cut the amount of benefit people can get if they are considered to have a spare bedroom.
According to the Housing Federation, around 50,000 households could be affected in the East Midlands.
Today protests are being held in cities throughout the Midlands.
Teen superstar Justin Bieber was also an hour late for a concert in Nottingham on Saturday night, according to the Nottingham Evening Post.
"My daughter was just so distraught we had to go before he was even on stage," one mother told the paper. There was no apology or anything – I'm disgusted."
Another parent complained that she paid £330 for her daughter to meet the Canadian singer but the experience lasted "no more than 20 seconds."
As the Home Affairs Select Committee acknowledges, undercover police operations are a vital element of the fight against organised crime and terrorism but it is crucial covert powers are used proportionately and that effective human rights safeguards are in place.
– Home Office spokesman
The Regulation of Investigatory Powers Act already provides strong safeguards but we recognise the system can be improved.
The Home Office is already working with the police and others to implement recommendations from HM Inspectorate of Constabulary.
The case that placed undercover policing in the spotlight was that of Pc Mark Kennedy who posed as a campaigner in protest groups over seven years from 2003.
He was outed by accident when his real passport was discovered. He went on to offer help to protesters in a trial regarding Ratcliffe-on-Soar power station, which led to the trial falling apart.
It was later revealed that he had had sexual relationships with at least two women in the protest movement.
A number of women who say they were deceived into having relationships with undercover officers - and not just Mark Kennedy - are suing the Metropolitan Police for damages.
Here are some of the conclusions from the Home Affairs Select Committee interim report.
On undercover policing:
We are not satisfied that the current legislative framework provides adequate protection against police infiltration into ordinary peoples' lives - a far more intrusive form of surveillance than any listening device or hidden camera.
On sexual relations:
We do not believe that officers should enter into intimate, physical sexual relationships while using their false identities undercover without clear, prior authorisation, which should only be given in the most exceptional circumstances.
In particular, it is unacceptable that a child should be brought into the world as a result of such a relationship and this must never be allowed to happen again.
On using dead childrens' identities:
The practice of 'resurrecting' dead children as cover identities for undercover police officers was not only ghoulish and disrespectful, it could potentially have placed bereaved families in real danger of retaliation.
The families who have been affected by this deserve an explanation and a full and unambiguous apology from the forces concerned.
Rt Hon Keith Vaz, chair of the Home Affairs Select Committee, has called for a "clear code of conduct" for police officers operating undercover.
He told ITV News that cases of undercover police officers fathering children with their subjects, or using the identities of children who have died, were "abhorrent".
"This isn't James Bond, this is happening," he added.
