One lucky Lottery winner, who bought their ticket in the Stevenage and Hitchin area, is sitting on a £64 million pot of gold - but has yet to claim the astonishing prize. The missing millionaire has just one week left to cash in the EuroMillions ticket, which is worth £63,837,543.60.
If the prize is not claimed by 11pm next Wednesday, the ticket will expire The winning ticket was bought for the EuroMillions draw on Friday June 8.
The all-important numbers on that date were 5, 11, 22, 34, 40 and the Lucky Star numbers were 9 and 11. The missing ticket-holder matched all five main numbers and both Lucky Star numbers.
If nobody comes forward to claim the prize, the money, plus all the interest it has generated, will go to the National Lottery Good Causes - adding to the £29 billion already raised through sales of lottery tickets since the National Lottery launched in November 1994.
A National Lottery spokesman said: "Our message is simple - we're urging everyone to look one last time everywhere a missing ticket could be hiding. The ticket-holder now only has until 11pm on December 5 to come forward and claim this huge prize."
Advertising vans displaying important information will be touring Stevenage and Hitchin this week, while retailers will be displaying posters up until the last minute to remind their lottery-playing customers to check their tickets.
Anyone who believes they have the winning ticket for any of the draws within the 180-day deadline should call the National Lottery Line on 0845 910 0000.
