The ticket-holder who scooped a massive £107.9 million on the EuroMillions draw has come forward to claim their winnings.
The claimant, whose identity has not been disclosed, has now staked their claim following last night's draw.
They had the only ticket to hit the jackpot, making them the National Lottery's fourth biggest winner.
A National Lottery spokesman said: "We're delighted Friday's ticket-holder has come forward to claim this amazing prize.
"This massive win ranks fourth biggest on the National Lottery Rich list and is the first EuroMillions jackpot to be won here in the UK so far this year."
Subject to validation, the windfall could be paid out once the banks open on Monday.
The ticket-holder can then decide whether or not to go public and share their news.
It is not known at the moment where the winning ticket was bought or whether it was won by an individual or syndicate.
This information will only be disclosed if the ticket-holder decides to go public.
The life-changing sum could help the winner buy their own Greek island such as Omfori, currently being advertised for just over £41 million, and a Lamborghini Veneno, one of the world's most expensive cars at a cost of £2.4 million, and still have plenty left to spend.
Or they could splash most of the money in a single purchase to buy a 21-bedroom home in London's Mayfair, which is on the market for £90 million.
Top of the National Lottery Rich List are Colin and Chris Weir, who banked a £161 million EuroMillions jackpot in July 2011.
Last night's main numbers were 6, 24, 25, 27 and 30, with the lucky star numbers 5 and 9.
