Roger Federer’s victory yesterday might have been a blow for British tennis, but it was good news for Oxfam which will pocket more than £100,000 from a bet placed by a man who left his estate to the charity.

Oxfam is putting the £101,840, enough to feed 10,000 people affected by the food crisis in West Africa for one month, into its unrestricted fund.

Nicholas Newlife, who left his estate to the charity in his will, placed the bet of £1,520 at 66/1 on Federer to win the men’s singles at Wimbledon at least seven times before 2020.

Andrew Barton, head of relationship marketing at Oxfam said: “All of Oxfam have been cheering Federer’s progress for the past couple of weeks. The real hero, though, must be Mr Newlife, for his generous gift and his tremendous sporting acumen.”

He added: “We hope Mr Newlife’s legacy – and Federer’s win – will inspire other people to support Oxfam and our West Africa appeal.”

Graham Sharpe, from William Hill, who took the bets said: “Normally we’d have mixed feelings about paying out such a hefty six-figure sum, but in this instance it seems that it was meant to be, and we are delighted that a sad story has had a very positive conclusion.”

The charity still stands to make up to £200,000 more from bets placed by Newlife on tennis player Andy Roddick and cricketer Ramnaresh Sarwan. In 2010 it claimed £16,000 from a bet that Federer would win 14 grand slam titles by 2020.

Each year Oxfam receives between £12m and £13m in legacies, which represents 12 to 13 per cent of its income to supporters. So far Newlife is the only person to have bequeathed betting slips. Other unusual legacies include a pair of gold teath and dentist’s chair (from a former dentist) and the royalties from books and plays, including Doctor Finlay’s Casebook.
