A UK ticket-holder has won a massive £148.6 million on Friday night's EuroMillions draw.
Lottery bosses are waiting for the lucky winner to come forward.
The prize is the second-largest jackpot yet in the UK.
It is the largest pot since Colin and Chris Weir, from Largs in North Ayrshire, won £161 million last July, with the difference in the exchange rate meaning this week's jackpot is slightly less.
A National Lottery spokesman said: "Lady Luck is clearly shining down on the UK once again with another big EuroMillions win this year - the seventh jackpot to be won so far in 2012.
"This new jackpot winning ticket-holder flies into second place in the exclusive National Lottery Rich List.
"We have plenty of champagne on ice and look forward to welcoming the lucky ticket-holder into the National Lottery millionaires' club."
The winning main EuroMillions numbers were 50, 21, 17, 48 and 11, and the Lucky Star numbers were 09 and 10.
The winning ticket collects £148,656,000.
