Have you forgotten £64 million lottery ticket?
So who has this ticket, and how does this compare in the league table of unclaimed winnings?
The winnerThe jackpot of almost £64 million has been waiting for almost six months without being claimed, after the winning balls were drawn on 8 June. There were two winners, one from Belgium who has made their claim, and one from the UK, who is yet to come forward. The winner has until Wednesday 5 December to cash in their ticket - so time is running out.
The winning numbers are 5, 11, 22, 34 and 40, with lucky stars 9 and 11. If these are your numbers, but you have lost the ticket then you're out of luck, because you only have 30 days to register a ticketless claim, so that Camelot can investigate. It means that you can only claim your lost fortune if you have the ticket.
It was bought in the Stevenage and Hitchin area of Hertfordshire, and there have been local campaigns to jog the winner's memory, to no avail. If no-one claims the prize it will go to the good causes fund. However, Camelot hasn't given up, it told the Daily Mail that in 2009 someone claimed a £2.5 million jackpot on the last possible day.
League tableThis doesn't mean, however, that there haven't been a fair few unclaimed jackpots. The National Lottery website lists a whole host of them which are still available to be claimed. They include a second prize from the same draw on 8 June, where someone is about to lose £103,000.
There are four millionaires who are yet to claim their £1 million jackpots in EuroMillions raffles last summer, and there's a lottery winner from the draw on 8 September, who is sitting on a ticket worth over £6 million.
In the UK the current record for missed jackpots is held by a winner in Doncaster in the 1990s, who missed out on £9 million.
In the US in 2009 (the last year anyone did the sums) $496 million went unclaimed across the country. The largest which can still be claimed is a $21.8 million prize from the Oregon lottery, followed by $16.5 million in Iowa.
And the record for largest sums ever unclaimed across the pond is an Indiana winner, who failed to collect $51.7 million in 2002.
If no-one comes forward, this latest £64 million unclaimed prize could become the largest in lottery history.
