Rage Against The Machine's 'Killing In The Name' is number one on the iTunes download chart after 24 hours of sales.

The Rage Against The Machine For Christmas No.1 Facebook group, which now has 717,000 members, has been urging fans to buy the 1992 rock anthem since one minute past midnight on Sunday.

The campaign was set up by Tracy and Jon Morter in protest at The X Factor's stronghold on the Christmas number one.

The Rage track had a 22 hour advantage over X Factor winner Joe McElderry's cover of Miley Cyrus' 'The Climb' which went on sale as a download after last night's final – viewed by 19million people.

The physical version of the X Factor single goes on sale on Wednesday.

Importantly, supporters of the Rage campaign have already generously donated £20,000 to the homeless charity Shelter. You can make a pledge to shelter HERE.

The iTunes chart is separate from the Official Chart Company chart, but serves as a good indicator of download sales.
