X Factor losing Christmas chart race to charity single
Despite high sales, James Arthur is second in the race for Christmas number one, the Official Charts Company says.
As it stands the X Factor winner has sold 3,000 fewer copies of his single, Impossible, than rival The Justice Collective, with their charity single.
He Ain't Heavy, He's My Brother, has been recorded to raise money to support victims of the Hillborough disaster and their families.
The song features musicians including Paloma Faith and Robbie Williams.
"This really is the closest battle we can remember - even closer than the 2009 battle between Rage Against The Machine and Joe McElderry," managing director of the Offical Charts Company, Martin Talbot said.
"The poll concludes at midnight on Saturday (22 December), so there is a long way to go - but this one looks like going down to the wire."
The last time a race for the Christmas number one was this close was in 2009 when X Factor winner Joe McElderry went up against Rage Against The Machine.
The Christmas number one will be revealed on Radio 1's Official Chart Show with Reggie Yates on Sunday 23 December. The Official Chart Update will be on Greg James' show today (19 December) from 4pm.
