The winner, from the draw on Friday October 8, is deciding whether or not to go public with the windfall.
The £113,019,926 jackpot is the biggest lottery prize to be paid out in the UK and the ticket-holder now sits at the top of the UK’s National Lottery Rich List.
A spokeswoman for Camelot said the winning ticket had been produced and verified.
The lottery operator revealed it had received more than 1,000 lost ticket claims relating to the massive jackpot.
The claims, coming from around the country, were understood to include some from people who have admitted they do not even know whether the ticket they mislaid matched the winning numbers.
One unnamed pensioner who believed her husband threw away her winning ticket was reported to have a written record of her “win”.
She told the Coventry Telegraph although she had noted down her winning numbers after buying a EuroMillions ticket, her husband had binned it by the time she realised her good fortune.
Aged in her 70s and living in Coventry, the woman told the newspaper: “I play the lottery, the EuroMillions and the Thunderball – but my husband takes the ticket off me and I don’t see it again.
“That’s why I always write my numbers down.”
