The £40,957,696.60 win was the seventh EuroMillions jackpot to be won in the UK this year.
One of the biggest prizes in history could go unclaimed.
Euromillions players in Dorset are being urged to check their favourite numbers as a deadline to claim the massive prize approaches.
The £40,957,696.60 win was the seventh EuroMillions jackpot to be won in the UK this year but, with the 30-day deadline for reporting lost destroyed or stolen tickets approaching, players are are being urged to look again so as not to miss out.
According to lottery organiser Camelot, the ticket-holder matched all five main numbers 18, 31, 32, 38 and 48 and two Lucky Stars 04 and 12 on the December 3 draw.
No further information, save for the county the ticket was purchased, has been released in case the winner wishes to remain anonymous.
Under the terms of Camelot’s license the operator has the discretion to pay on a lost, destroyed or stolen ticket only if the player has submitted a claim in writing by 5pm on January 2.
Camelot will then determine whether the claim is valid, and would then pay the prize 180 days after the draw date.
The absolute deadline for those who have their winning tickets is midnight Sunday 31 May, 2020.
Andy Carter, senior winners’ adviser at The National Lottery, said: ‘It’s important that any player who is not in possession of their ticket for whatever reason but who thinks they have a genuine claim to the prize notifies us in writing by 5pm on January at the latest.
‘We’re doing all we can to reunite the ticket-holder with this amazing £40 million win – one of the biggest unclaimed prizes ever.
‘The festive period is such a busy time for everyone and in all the excitement it’s possible that the winning ticket might have been somehow misplaced.
‘What a start to the new year it would be for the lucky ticket-holder if they were to check their tickets and claim their prize.
‘We have our fingers crossed that we’ll soon be welcoming our seventh UK EuroMillions jackpot winner of 2019.’
If the ticket remains unclaimed before the May 31 deadline, the prize money, plus all interest generated, will go to help National Lottery-funded projects across the UK.
