'X-Factor' faces competition for Christmas number one spot

The 'X Factor' winner will face challenges from The Wombles, Nirvana and 'The Only Way Is Essex' stars for the Christmas number one, according to bookies.

The yet-to-be-decided victor of the ITV1 talent show is favourite – as in most years – but William Hill has seen a flurry of bets which have cut the odds of challengers considerably.
