The lucky UK winner who scooped £22.1 million in Friday night's EuroMillions Lottery has not yet come forward to claim the life-changing prize, Camelot has said.
The new multi-millionaire hit the jackpot with the numbers 5, 6, 11, 30, 44 and matched the lucky star numbers 2 and 6.
The ticket-holder becomes the fourth UK winner of the prize in several weeks.
A spokesman said: "It's amazing to have another big winner here in the UK - we've been extremely lucky in recent years.
"As well as the chance to win a life-changing prize, EuroMillions players have also helped raised over £27 billion for National Lottery Good Causes, benefiting communities across the UK."
Last month Cassey Carrington and Matt Topham, both 22, from Stapleford in Nottingham, won a massive £45,160,170.50.
