Someone, somewhere in Sussex has a lottery ticket worth more than £150,000 - and they may not even know it.

The mystery winner bought the lucky ticket in the West Sussex area and has just a few weeks left to claim the National Lottery prize.

Someone bought the ticket for the draw on Saturday, June 16, but failed to contact Camelot to claim their £154,250 prize.

The lucky numbers for that week were 7, 25, 31, 35, 39, 45 and the bonus number was eight.

The ticket holder has until 11pm on Thursday, December 13 to claim the money.

If the deadline is missed the money, plus the interest it has generated, will go to good causes.

Sam Hudson from Camelot, which operates the National Lottery, said: "Maybe you've got the dream ticket. I'm ready to pay out the prize and I wouldn't want to see this money go unclaimed."

"I'd like to encourage everyone to check their tickets, as time is running out."

Camelot says the ticket could have been bought by someone who was visiting West Sussex, possibly in the Chichester area.
