The lucky player matched all five Euromillions numbers as well as the two Lucky Star numbers to scoop the massive prize, the National Lottery has said.
The ticket holder’s winning numbers were 04, 21, 34, 40, 47, and the Lucky Star numbers were 02 and 05.
Players are now being urged to check their tickets in order to claim the prize of £122,550,350.80.
Camelot’s Andy Carter, senior winners’ adviser at The National Lottery, said: “What brilliant news, one UK winner has scooped tonight’s massive £122 million EuroMillions jackpot.
“They are now the fifth biggest ever National Lottery winner.”
It is the second UK EuroMillions jackpot winner this year, after another lucky ticket-holder won the £39 million jackpot in the draw on New Year’s Day.
