Lottery players in South Yorkshire have been urged to check pockets, bags, wallets and even the back of the sofa after a £1 million-plus prize went unclaimed.
The jackpot-winning ticket was bought in Barnsley for the draw on Saturday, June 11.
The ticket-holder is in line for a £1,158,038 windfall if they come forward before the beginning of December.
The winning Lotto numbers on that date were 9, 11, 35, 37, 40, 45 and the bonus ball was 26.
The lucky ticket-holder has until 5.30pm on Thursday, December 8, to make their claim.
A National Lottery spokeswoman said: “We’re desperate to find this mystery ticket-holder and unite them with their winnings.
“This amazing prize could really make a huge difference to somebody’s life. We’re urging everyone to check their old tickets again or look anywhere a missing ticket could be hiding.
“Try checking in the pockets of clothing, in wallets, bags and down the back of the sofa - someone out there could literally be sitting on a fortune.
“We have the champagne on ice and our fingers crossed that the lucky winner comes forward to claim their win.”
If no-one comes forward with the ticket before the deadline the prize money plus all the interest it has generated will go to good causes.
