X Factor champion Leon Jackson has said that winning the fourth series of the show is “the best Christmas present ever”.

The 18-year-old, from West Lothian in Scotland, was a surprise winner of the show on Saturday night, beating hot favourite Rhydian Roberts into second place by just one per cent of the public vote.

“It just means the world,” he said afterwards, “I love singing. I’m really pleased that I’ve done my country proud, and been the first Scot winner.”

And he added that the victory would change his life and that of his mum.

“I’m stunned,” he told reporters. “My birthday’s just after Christmas, and this is probably the best birthday and Christmas present I’ve had in my life.”

The teenager’s mum Wendy described Leon’s win as “absolutely amazing”.

“Every week I’ve just watched him grow and grow and get better and better and he just blew me away,” she said.

The bookmakers were also celebrating Leon’s victory – since it saved them from a massive payout on Rhydian. Leon went into the final as the 6-1 outsider, compared to Rhydian’s odds of 1-3.

“Leon’s win is the biggest shock in the history of reality TV betting,” said Ladbrokes spokesman Nick Weinberg.

“He saved us from a bumper payout. He’ll definitely be top of our Christmas card list.”

Meanwhile, disappointed Rhydian fans have complained that they were unable to get through to vote for their favourite, according to reports.

The BBC news website says that several viewers contacted them to say they had been unable to cast their vote.

However, a spokeswoman for ITV said there had been no problems with the voting lines but some people may have had trouble getting through due to the high volume of callers casting votes.
