The lucky UK-ticketholder who scooped a massive £37 million on Friday's EuroMillions jackpot has banked their winnings but decided to remain anonymous, Camelot said today.
The whopping £37,827,314.60 prize was won by just one ticketholder.
It is the 14th-largest jackpot win ever in the UK and the eighth big British EuroMillions triumph this year.
Lottery operator Camelot said no further details will be released about the winner.
A spokesman said: "The UK's run of EuroMillions luck continues - this is the eighth jackpot banked on these shores in 2012.
"In addition to the chance to win a life-changing prize, EuroMillions players contribute to the £30 million raised every week for National Lottery Good Causes, benefiting communities across the UK."
Top of the National Lottery Rich List are Colin and Chris Weir from Largs in Ayrshire who banked £161 million in July last year.
Just last month Adrian and Gillian Bayford, of Haverhill, Suffolk, won the second-largest jackpot yet in the UK, taking home £148 million.
Friday's winner is placed behind the syndicate of 12 bus drivers from Corby, Northamptonshire, who won £38 million in March and ahead of Angela Kelly from East Kilbride, who won £35 million in August 2007.
The winning main EuroMillions numbers were 13, 15, 30, 35, and 42, and the Lucky Stars were 4 and 6.
