Turn out your pockets and check down the back of the sofa because you could be holding a winning ticket for the lotto draw on Saturday, July 28.

A prize of £55,153 is yet to be claimed in the Swale area although Camelot refuses to say exactly which part of the borough the ticket was bought in.

The winning numbers on that day were 7, 10, 22, 29, 43, 44 and the bonus ball was 26. The lucky ticket-holder has until Thursday, January 24, 2013 to claim their prize.

If no-one comes forward with the winning ticket before the deadline, the prize money, plus all the interest it has generated, will go to The National Lottery Good Causes.

A spokesman 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.”

• Anyone who believes they hold the winning ticket for any of the National Lottery draws within the 180-day deadline should call the National Lottery Line on 0845 910 0000.
