The ticket for an unclaimed £63.8 million EuroMillions jackpot was bought from a shop in the Stevenage and Hitchin area, the National Lottery has revealed.
The prize won by a UK ticket holder remains unclaimed nearly a fortnight after the draw.
There were two jackpot winners in the June 8 draw - one in Belgium and one in the UK. But the owner of the British lucky ticket - who could be an individual or a syndicate - is yet to come forward to collect their £63,837,543.60 prize.
