The National Lottery is on the hunt for a EuroMillions UK Millionaire Maker winner in Harrow or Brent who is sitting on a £1m ticket.

The unclaimed ticket is thought to have been bought in either Harrow or Brent and Camelot, who runs the National Lottery, has encouraged all players who purchased one there to double-check their tickets.

The winning code on April 30 this year for the prize - the only one from the draw yet to be claimed - was ZVWT 35504 and the lucky ticket-holder has until October 27 to claim their prize.

Anyone who believes they had the wining ticket, but no longer possesses the ticket, can still make a claim in writing to Camelot within 30 days of the draw.

Camelot’s Andy Carter, Senior Winners’ Advisor at The National Lottery said, “We’re desperate to find this mystery ticket-holder and unite them with their winnings. This amazing prize, from the amazing draw when 10 UK millionaires were made in one night, could really make a massive difference to somebody’s life. We’re urging everyone who bought a ticket in this area to check their old EuroMillions tickets again or look anywhere a missing ticket could be hiding.

“We’re encouraging everyone to check their tickets online at national-lottery.co.uk or by downloading the National Lottery app, and to buy or check their tickets in retail in line with government guidance. Playing online via the website or app means that your ticket is checked, and you get an email notification if you win a prize. You can also scan your retail tickets on the National Lottery app to check if you're a winner.

“Try checking in the pockets of clothing, in wallets, bags and down the back of the sofa. 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 winning ticket before the prize claim deadline, then the prize money, plus all the interest it has generated, will go to help National Lottery-funded projects across the UK.
