National Lottery players are being urged to check and double-check their tickets for the chance to claim this life-changing prize.
The search is now on to find the owner of the winning ticket, bought in the Royal Borough of Kingston upon Thames, who matched the five main numbers and one Lucky Star number in the EuroMillions draw on December 5, 2023.
The winning EuroMillions numbers on that date were 4, 6, 20, 24, 25 and the Lucky Star numbers were 5 and 9.
The lucky ticket-holder has until June 2, 2024, to claim their prize.
Anyone not in possession of their ticket, for whatever reason, but who believes they have a genuine claim can still make a claim in writing to Camelot, but it must be within 30 days of the draw.
Andy Carter, Senior Winners’ Advisor at The National Lottery said: “If you bought a EuroMillions ticket in the Royal Borough of Kingston upon Thames for the draw on December 5, it’s time to look everywhere – in the pockets of clothes you might have been wearing at the time, bags, in the car, wallets and purses and in that sideboard or drawer where we all tend to put bits and pieces – and check your tickets.
“Do you live or work in this area, do you have family and friends there who you were visiting, were you just passing through or were you hitting the town for an early Christmas party?
“We’re desperate to find this mystery ticket-holder and pay out their life-changing prize – imagine the possibilities for them, especially with Christmas now only a matter of days away!
“We have the champagne on ice and our fingers crossed that the lucky winner comes forward to claim their win.”
