A British 'millionaire' has only days to claim the huge lottery prize, but their identity remains a mystery.
A customer, who bought the winning ticket in London, has yet to claim their prize after scooping the EuroMillions UK Millionaire Maker cash worth £1million.
The deadline for the lucky ticket holder to come forward is looming with just 16 days left for the ticket holder to claim the windfall.
The National Lottery has issued several appeals about the mystery winner and is calling on anyone who bought a ticket in Harrow, northwest London, on April 30 to check their ticket.
If no one comes forward by October 27 with the winning ticket, the prize money plus all the interest it has generated will go to help National Lottery-funded projects across the UK.
Camelot's Andy Carter, senior winners' advisor at The National Lottery, said: 'Time really is running out for the winner of this prize, but we are still hopeful that someone will come forward at the very last minute to claim the money.
'We're urging everyone to check their old tickets one final time or look anywhere a missing EuroMillions ticket could be hiding. This life-changing prize could really help to make dreams become a reality for someone out there.
'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.'
The Harrow winning ticket matched winning code ZVWT 35504.
Anyone who has any queries or who believes they have the winning ticket for any of the National Lottery draws within the 180-day deadline can call the National Lottery Line on 0333 234 5050 or email firstname.lastname@example.org.
