Lotto winner Mark Gardiner has said he would give away all his wealth to save his critically ill nephew.

Multi-millionaire Mark’s 21-year-old nephew, Philip Pain, is fighting for his life in Mexico after plunging from a seventh-floor hotel balcony on New Year’s Day.

The popular student has been put into a coma by doctors who have given him drugs to try to help his body recover from the fall.

He suffered two broken legs, a broken lower back and crushed internal organs and needs a transfusion before doctors can operate but no donors have been found for his Type O-negative blood.

The blood group is shared by only a small fraction of the world’s population. None of Philip’s close family have it and appeals on Mexican radio and BBC World Service have failed to produce anyone who could help.

Mark, from Hastings, who banked a half share of £22.6 million in 1995, then Britain’s biggest national lottery payout, said: “All the money in the world cannot help in a situation like this but if it meant saving Philip then I would give away every single penny.

“Philip has given blood many times before, but it’s now him who needs vital life-saving treatment.”

Philip travelled to Mazatlán, a city on Mexico’s Pacific coast, in October to spend a year practising Spanish as part of his Latin American studies degree at the University of Southampton.

He had been out celebrating the New Year with friends and returned to his hotel at about 3am.

Mystery surrounds the circumstances of his fall from the balcony.

A toxicology report does not appear to show any signs of drugs or excessive alcohol consumption in the 21-year-old’s system.

His parents have flown out to Mexico to be with him at the Hospital Sharp in Mazatlán.
