Lottery chiefs are today waiting for the UK ticket-holder who scooped a huge £37 million on the EuroMillions draw to come forward.
The prize won on Friday night is the 14th-largest jackpot win ever in the UK and the eighth big British EuroMillions triumph this year.
A National Lottery spokesman said: "This is amazing. Just a month after Adrian and Gillian Bayford scooped £148 million we have another UK ticket-holder banking the EuroMillions jackpot.
"It has been an extraordinary year for UK ticket-holders - this is the eighth EuroMillions jackpot to be won on these shores in 2012.
"This new jackpot winning ticket-holder now sits 14th on the exclusive National Lottery Rich List.
"Our Winner Services team is on hand ready to validate the ticket and pay out the prize, and of course we have plenty of champagne on ice.
"Over 2,900 people have become millionaires since The National Lottery began and, to date, our players have raised an amazing £28 billion and counting for National Lottery Good Causes."
Adrian Bayford, and wife Gillian, of Haverhill, Suffolk, won the second-largest jackpot yet in the UK after taking home £148 million last month.
In February Cassey Carrington and Matt Topham, both 22, of Stapleford, Nottinghamshire, scooped £45.1m.
Husband and wife Gareth and Catherine Bull from Mansfield won £40 million a month earlier.
A consortium of bus drivers from Corby, Northamptonshire, pocketed £38 million in March, while anonymous winners picked up £22.1 million that month and £46.4 million in February.
A ticket worth £63.8 million bought in Hertfordshire last June has not been claimed.
Last night's winning main EuroMillions numbers were 13, 15, 30, 35, and 42, and the Lucky Stars were 4 and 6.
The winning ticket is worth £37,827,314.
