A claim has been staked for the £122 million EuroMillions jackpot won on Friday by a single UK ticket-holder.
The player matched all five EuroMillions numbers as well as the two Lucky Stars to win £122,550,350.80.
Camelot said the claim will now go through the process of validation.
Subject to those checks, the prize will then be paid out.
Andy Carter, senior winners’ adviser at the National Lottery, said: “What an Easter weekend for one lucky player.
“They have become the fifth biggest winner in UK National Lottery history and have a fortune which can make their dreams come true.
“We will now look to support the ticket-holder through the process and help them to start to enjoy their life-changing win.”
The winning numbers are 04, 21, 34, 40, 47, and the Lucky Stars are 02 and 05.
It is the second UK EuroMillions jackpot winner this year, after another lucky ticket-holder won the £39 million prize in the draw on New Year’s Day.
The lucky winner, whoever they are, may wish to celebrate with wine and flowers and could now afford a bottle of Krug Collection 1988 champagne, at £890 a bottle, and a Cullinan bouquet for an eye-watering £20,000.
And while holiday bookings are still uncertain for Britons this summer, they could treat their partner to a private island, such as Cave Cay in the Bahamas – costing 60 million dollars (£43 million) – which they could afford to buy, twice.
The win will also put them into the top 1,000 on the Sunday Times Rich List 2020.
The highest ever UK winner claimed a jackpot of £170 million in October 2019, but chose to stay anonymous.
Colin Weir and wife Chris, from Largs in North Ayrshire, claimed the second highest prize – £161 million – in July 2011.
The couple set up the Weir Charitable Trust and made a donation to a community football club in Largs before Mr Weir’s death in 2019 after a short illness.
Adrian and Gillian Bayford, from Suffolk, took home more than £148 million in August 2012 and the fourth highest UK winner – who took home £123 million – also remained anonymous.
The record for the highest amount ever won on EuroMillions was set in February this year when a Swiss player took home 210 million euro, the equivalent of almost £180 million.
