Camelot will today reveal the identity of a lucky car mechanic who scooped a staggering £107.9 million on the Euromillions.
The mystery man, who is also a racing driver, will discuss his plans for the future when he speaks at an event later.
The claimant, from Coulsdon, in Surrey, had the only ticket to hit the jackpot from Friday's draw, making him the National Lottery's fourth biggest winner.
After the as-yet unnamed man came forward to collect his winnings, 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."
The winner will be unveiled at Wotton House in Dorking, Surrey, Camelot said.
The sum could help the winner buy their own Greek island such as Omfori, 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.
Friday's winning numbers were 6, 24, 25, 27 and 30, with the lucky star numbers 5 and 9.
