A single UK-bought ticket has won the £184 million EuroMillions jackpot, becoming the UK's biggest ever National Lottery winner.
Lottery operator Camelot confirmed the win.
Andy Carter, senior winners' adviser at The National Lottery, said: "What an amazing night for one UK ticket-holder who has scooped the incredible £184 million EuroMillions jackpot - they have become the UK's biggest ever National Lottery winner.
"Players are urged to check their tickets and give us a call if they think they are tonight's lucky winner."
The winning EuroMillions numbers were 3, 25, 27, 28 and 29 - plus the Lucky Star numbers 4 and 9.
What will £184m buy me?
The winner can now buy four Caribbean islands, with a few million to spare, or the equivalent of 11 six-bedroom luxury properties in London's affluent Hyde Park.
The winner will also be catapulted to the top of the National Lottery's rich list.
Only 14 players have ever won a jackpot of more than £100 million, with the previous record-holder an anonymous winner of £170 million in October 2019.
One ticket matched all seven numbers to win £184,262,899.10.
