A LOTTERY player who bought a ticket in Harrow could literally be sitting on an unclaimed prize of £144,530.
The slip, entered in the draw of Wednesday March 10, matched five numbers out of 1, 6, 13, 23, 29, and 34 as well as the bonus ball, 37.
Whoever holds the ticket has until 5.30pm on Monday September 6 to claim their winnings after which it will be all donated to charity.
A National Lottery spokesperson 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."
