Greece beat the hosts Portugal 1-0 in the final on Sunday night.

Paul Williamson used promotional offers from by on-line bookmakers to double his �150 stake on the outsiders before the tournament kicked off.

He is celebrating by taking his wife Ann-Marie and their two daughters, Lauren, 12, and Lucy, eight, on holiday to Greece next week.

The Greeks beat the tournament hosts Portugal 1-0 in the final in Lisbon on Sunday evening.

Greece had come through a difficult qualifying stage - when you get to the last 16 anything can happen Paul Williamson

Mr Williamson, 39, missed the first half of the game as he was playing cricket for Sully Cricket Club in a rain-delayed cup match at Usk.

"I was fielding during the first half and asked to be put near the clubhouse so I could ask people what the score was," he explained.

"I love playing cricket and it was more important than the money."

As soon as his match was over he and his team-mates watched the second half in the clubhouse still dressed in their cricket whites.

"I had promised to but them a drink if I won and it cost me �150 at the bar," he added.

He has already booked a family holiday in Corfu and jets out of Cardiff Wales Airport on Monday.

He will also invest in new slides at the House of Play after-school activity club he runs with his wife in Fforestfach, Swansea.

Mr Williamson said he was not usually a big gambler.

"I like to have a friendly bet on pool or darts when playing with friends.

"I thought Greece would be a good bet because a lot of the teams were poor value.

"Greece had come through a difficult qualifying stage - when you get to the last 16 anything can happen."

He said in the weeks leading up to the competition some on-line bookmakers were offering a free �30 bet for anyone betting �30 on a new account.

He used both his and his wife's debit cards to place bets with five different companies.

"Effectively I got of odds of 160-1," he said.
