A UK ticketholder has scooped a £63.8 million share of the EuroMillions jackpot.
It is the sixth time a winner has come from Britain this year.
Last July Colin and Chris Weir, from Largs in North Ayrshire, won £161 million.
Other big winners include a ticketholder who banked £113,019,926 in October 2010 but decided not to go public, and Dave Dawes and wife Angela, from Wisbech, Cambridgeshire, who claimed £101,203,600 last October.
Friday night's massive pot came about because of a double-rollover when no-one matched all seven numbers to claim the £106 million jackpot in last week's draw.
A spokeswoman said: "Lady Luck is clearly shining down on the UK once again with another big EuroMillions win this year.
"We've got the champagne on ice and look forward to welcoming the ticketholder into the National Lottery millionaires' club."
If he or she is looking for a glass of champagne to celebrate their luck, they could go for a limited edition 12-bottle case of Pernod-Ricard Perrier-Jouet which sell for around £32,000 each.
Or they could treat themselves to 450 pairs of the world's most expensive shoes, £140,000 diamond-encrusted heels made by the House of Borgezie.
Or they could buy all 20 special edition Sesto Elemento Lamborghinis at £1.9million each.
A private jet can cost around £15m, while a luxury yacht is priced in the region of £13m - a drop in the ocean for the EuroMillions winner.
