A player in Switzerland scooped a huge £43.9 million (US$83 million) Lottery jackpot Friday night.
The Euro Millions prize the biggest since the game began in February of 2004 created a 400% surge in UK ticket sales.
Ben Rosier, spokesman for National Lottery operator Camelot, said: There was one lucky jackpot winner in Switzerland, so one mystery player has just become very, very rich.
The winning numbers in Friday's EuroMillions draw were 31, 50, 25, 11, 07 and the Lucky Stars were 03 and 01. The total jackpot was £43,960,693.
Next weeks Euro Millions jackpot will be an estimated £10 million, Camelot said.
The previous biggest National Lottery jackpot was on January 6, 1996, when three winning tickets shared a Lotto jackpot of more than £42 million.
