The hunt is on for the owner of a winning lottery ticket worth more than £11m.
Camelot said the £11,165,532 Lotto jackpot was won by a single ticket-holder following the draw on August 14 2021.
Another person is due £1m after winning the UK Millionaire Maker prize in the EuroMillions draw on August 13 2021.
The mystery Lotto winner, who matched all six main numbers, bought their ticket in a shop, while the EuroMillions winner bought their winning ticket online.
Players of each draw are urged to check their tickets to claim the “life-changing” prizes.
Camelot’s Andy Carter, senior winners’ adviser at The National Lottery, said, “It’s just a week ago that these two life-changing prizes were won by two lucky ticket-holders who have yet to claim their prizes.
“We’re asking National Lottery players to check their tickets – for the Lotto jackpot prize this is the physical paper ticket while for the EuroMillions Millionaire Maker prize we’re asking players to log into their National Lottery account to check, as this win was online.
“These could be life-changing wins for two lucky ticket-holders and we’re hoping that both winners will now come forward and claim their amazing prizes.”
If a ticket worth more than £50,000 and won in retail has not been claimed after two weeks, Camelot will announce the area in which it was bought.
Players have 180 days from the day of the draw to claim their prize if they have the winning ticket.
