A UK ticketholder has won Friday's £110m EuroMillions jackpot, Camelot says.
The winning numbers were 07, 12, 13, 20 and 45 - while the Lucky Stars were 03 and 12.
Andy Carter, Camelot's senior winners' adviser at the National Lottery, said: "Players are urged to check their tickets and to give us a call if they think they are tonight's lucky winner.
"Thanks to National Lottery players, more than £30m is generated every week for good causes across the country.
"This supports everything from local projects making a difference where you live, to our nations' athletes at the recent Commonwealth Games."
Only 15 UK players have ever won a jackpot of more than £100m, with the record-holder winning £195m in July.
That lucky player was not identified - but in May, Gloucester couple Joe and Jess Thwaite decided to reveal themselves as the winners of £184m.
They spoke to reporters about the shock and disbelief they felt when they found out they had won what was then Britain's biggest lottery win.
