'X-Factor' winner falling behind Rage Against The Machine in chart race

'X-Factor' winner Joe McElderry is trailing in the race with Rage Against The Machine to become the UK Christmas number one.

Sales figures show his single has been outsold over the last 24 hours by the rock band's classic "Killing In The Name".

It is being backed by an anti-Simon Cowell campaign on the internet.

Experts say that McElderry could overturn the lead when "The Climb" is released on CD tomorrow.
