Leona Lewis looks set for yet another No. 1 single this week with her cover of the Snow Patrol track 'Run'.

The mid-week charts puts the 2006 X-Factor winner well ahead of nearest rivals, Take That, with nearly 100,000 sales, all on downloads alone making it the fastest selling digital release ever.

Bookmakers have put Leona at 14/1 to pick up this years Christmas No.1, behind the 2008 X Factor Winner (favourite at 1/5) and Terry Wogan, at 4/1.

Snow Patrol got to Number 5 in the UK charts when they first released Run in 2003.
