A 24-year-old British man was found dead in a ski resort, the Foreign Office said today.
Police believe Paul Rea wandered off and got lost in freezing temperatures after becoming separated from friends on a night out in Pas de la Casa in Andorra.
His body was discovered on Friday covered in snow in the Envalira tunnel close to the French border.
A spokesman for police in Andorra told Spanish news agency Europa Press the body showed "no signs of violence" and it was likely Mr Rea died of hypothermia.
He said police believed he became "disorientated" and headed off in the wrong direction away from the centre of the resort.
A Foreign Office spokeswoman said: "We are aware of the death of a British national in Andorra on March 12.
"Next of kin are aware. We are providing consular assistance and a post-mortem is under way."
The post-mortem examination was carried out on Friday.
