The National Lottery has been unable to trace the owner of a winning EuroMillions raffle ticket that was bought in Bolton on July 26, last year.
Lottery officials were so desperate to find the missing winner they enlisted the help of Bolton's existing EuroMillionaire Brian Caswell, who won a £25 million jackpot in 2009.
Speaking to The Bolton News, Casswell made an appeal for Bolton players to check their pockets. "Once it’s gone, it’s gone," he warned. "It will be no good finding it in a month."
The 180 day deadline passed on Wednesday at 11pm and the prize, along with any interest earned, will now go to National Lottery Good Causes.
