"LISTEN very carefully. I shall say this only once . . ."

'Allo 'Allo star Gorden Kaye was back in his hometown of Huddersfield today to track down one lucky person in line for a £250,000 National Lottery windfall.

The mystery winner has just days to find their jackpot-winning Thunderball ticket and claim the life-changing cash prize.

The winning numbers on the ticket, issued on August 30 last year, are 18, 21, 24, 25 and 26. The Thunderball number is 3. The deadline for handing in the winning line is 11pm a week on Thursday.

Gorden was joined by another last-minute winner, Chris Jackson (left), in an effort to jog people's memories.

Chris, from Southend, was sleeping in has car, out of work and £6,500 out of debt when he discovered, with just a week to go, that his was a winning ticket.

"I was living in a car park in my car and visiting an airport to use the showers," said Chris. He found the old ticket in a shoe box.

"Just look everywhere," he urged the mystery winner.

Gorden added: "It could be you!"

He said there appeared to be two schools of lottery buyers.

"When I worked in the West End people would come very late on a Saturday night because they had been at home checking the lottery.

"But I find it hard to understand why people buy a ticket and don't check it."

Jacquie Wilson, from National Lottery operator Camelot, said:

"Someone in Huddersfield is very wealthy and they don't even know it yet! We really don't want the winner to miss out on this fantastic prize."

Anyone who thinks they have the winning ticket should contact the National Lottery line on 08459 100 000.
