The largest lottery prize in UK history has been claimed and paid out, nearly two weeks after the draw was made, Camelot has announced.
The £113m Euromillions rollover jackpot had gone unclaimed since 8 October.
Camelot said a winning ticket had been produced and verified, but did not reveal any further details.
"The ticket-holder is currently deciding whether or not to go public and share their news," a spokeswoman said.
The prize is also the biggest in Euromillions history, beating the record of a Spanish player who netted £111m in May 2009.
On Tuesday, Camelot revealed it had received more than 1,000 lost ticket claims relating to the £113m jackpot.
Using figures in the Sunday Times Rich List 2010, the ticket-holder, if it is an individual and not a syndicate, will become the UK's 589th wealthiest person.
The winner beat odds of more than 76 million to one to pick the winning numbers which were 9, 30, 35, 39, 46, with lucky stars six and eight.
Their wealth will eclipse that of the likes of pop stars Barry and Robin Gibb of the Bee Gees, who are said to be worth £110m, Phil Collins, who has a fortune of £108m, Rod Stewart, who has £105m, and David Bowie, who has an estimated £100m to his name.
About 2,400 lottery millionaires have been created in the UK since the National Lottery launched in 1994.
The previous largest lottery winner in the UK was an anonymous player who scooped £84.4m, also on Euromillions, in May.
Nigel Page and Justine Laycock, from Barnsley, Gloucestershire, previously broke the record in February after winning £56m on Euromillions.
Tickets for Euromillions are sold in nine countries - the UK, France, Spain, Austria, Belgium, Luxembourg, the Irish Republic, Portugal and Switzerland - with ticket-holders in all those countries trying to win a share of the same jackpot each week.
Camelot is the operator for the competition in the UK.
