One lucky ticket-holder has claimed £35.1 million in the Lotto draw, the biggest prize ever won in the game, the National Lottery said.
A National Lottery spokesman said: "In tonight's draw, one ticket-holder has scooped an amazing £35.1 million jackpot, the biggest prize ever won on the game, and a truly life-changing amount of money."
Later they added: "We can confirm we’ve had a claim staked for the Lotto jackpot prize won in last night’s draw. In the draw, one ticket-holder scooped the £35,133,888 jackpot, the biggest ever prize won on Lotto.
"The prize will be paid out at the ticket validation appointment. The ticket-holder will then decide whether or not to go public and share their news."
The winner will take home £35,133,888 for matching all six numbers.
The winning numbers in Wednesday night's draw were 50, 57, 31, 17, 41, 15 and the bonus number was 5. Set of balls one and draw machine Arthur were used.
It is the second big win this year.
In January this year, two Lotto ticket holders broke a 21-year-old record, splitting a £66 million jackpot that was the result of 15 rollovers.
One of the winning tickets was claimed by David and Carol Martin, a couple living in the Scottish Borders. The other winner remained anonymous.
A few weeks later, Gerry and Lisa Cannings, from Deeping St James, near Peterborough in Cambridgeshire, snapped up £32.5 million.
The previous record was a jackpot of £22.5 million, claimed by two business partners from St Leonards-on-Sea in 1995.
In 1996, three winners shared a £44 million prize, taking home £14 million each.
Meanwhile, Saturday's estimated jackpot is £4.2 million.
Nobody matched five numbers plus the bonus ball, but 35 people matching five numbers won £1,914 each.
There were 2,769 winners who matched four balls and they will take home £156 each.
Matching three numbers each, 70,801 tickets scooped £25.
As well as the winner of the £1 million prize Millionaire Raffle, there were 20 additional ticketholders who scooped £20,000 each.
No-one won the top prize of £350,000 in the Lotto HotPicks draw.
In the Thunderball draw the winning numbers were 39, 23, 04, 20, 16 and the Thunderball number was 02.
No-one scooped the top prize of £500,000.
This most recent jackpot is dwarfed by the Euromillions draw, which regularly sees jackpots of more than 100 million euro (£80 million).
Euromillions is drawn every Tuesday and Friday.
It has a jackpot cap of 190 million euro (£152 million), which has been won twice - once by Britons Gillian and Adrian Bayford, from Haverhill in Suffolk, who took home more than £148 million in August 2012.
The biggest ever prize won by a British couple was £161 million, pocketed by Colin and Chris Weir of Largs in North Ayrshire, Scotland, in July 2011.
Despite their prize not being the 190 million euro jackpot, they won more in pounds sterling because of fluctuations in the exchange rate.
