The clock is ticking on a EuroMillions ticket holder to claim their £12m prize money or lose the lot.

As another Briton comes to terms with scooping the £26.8m EuroMillions jackpot on Tuesday, a final call has gone out to the mystery winner who bought their lucky ticket in May but has still not claimed the prize.

National Lottery said that the holder of the winning EuroMillions Millionaire Raffle ticket has until 11pm tonight (26 November) to claim the jackpot before the deadline expires.

The ticket, featuring the winning raffle number JRG437445, was bought in Ladywood in Birmingham on 31 May. If the money is not claimed before the deadline, it will be donated to charity.

Officials have stepped up their efforts to find the missing ticket holder, with Lord Mayor of Birmingham Mike Leddy even starting a countdown clock in the city centre.

A National Lottery spokesperson told the Birmingham Mail: "We're desperate to find this mystery ticket-holder and unite them with their winnings.

"We have the champagne on ice and our fingers crossed that the lucky winner comes forward to claim their win."

Patrick Lisoire, of Camelot, the lottery promoter, said the company had not given up on finding the winner.

He said: "A prize in the Midlands of about £2.5m a few years back was claimed in the last 24 hours before the deadline.

"One hundred and seventy-nine days elapsed before the claimant claimed their prize. We never knew the reason they took so long."

The largest uncollected jackpot was £64m on a winning ticket bought in December 2012.

The National Lottery lines are open for the missing winner on 0845 910 0000, or email

Tuesday's winner was the only person to match all five numbers 19, 23, 27, 42 and 44 and the lucky stars (3) to claim the £26,863,588 jackpot.
