Britain’s latest big national lottery winner put his £19m windfall in perspective on Tuesday by offering to give it all back in return for good health.

Stephen Smith, a former hospital porter with a blood vessel condition which could kill him at any time, said he would swap his entire winnings in exchange for a guaranteed long life with his wife, Ida, in their one bedroom council flat.

In striking contrast to other Lotto millionaires’ plans for mansions and holidays, Smith (58), said he would do the “cash-for-life” deal “in a second”. But money can make no difference to the statistical threat of his aortic aneurism bursting, with only a one-in-10 chance of survival if that happens. “It’s a ticking timebomb inside me,” he said on Tuesday.

“It’s her [Ida] I worry for, it’s leaving her behind. I would give all that back if I am allowed to still be with her.”
