James Arthur leads the Christmas chart battle, bookies favourite Justice Collective are hot on his heels though

James Arthur's winner's single was released a week before the race to Christmas number one  in order to avoid a chart battle with charity track 'He Aint Heavy, He's My Brother' by the Justice Collective.

However, it seems that music lovers are still very much into James Arthur' debut number one track 'Impossible'.

According to the Official Chart Company, the X Factor winner is currently leading race to this year's Christmas number one.

Who'd have thought it?

The Justice Collective is currently just over 3,000 copies behind James despite being hotly tipped by bookies to take the top spot this Christmas.

Despite the early lead, bookmakers are still backing the Justice Collective as firm favourites to win the race but have slashed James' odds from 11/2 to 2/1.

In previous years, the X Factor's winner's single had dominated the Christmas number one.

This was until 2009 when a petition to stop Joe McElderry from taking the pole position proved successful and Rage Against the Machine's 'Killing in the Name' won out.

What a festive treat that song was.

Matt Cardle did regain the X Factor's dominance over the Christmas number one a year later but much like this year, 2011's winner's single from Little Mix was released a week early too.

James Arthur's single 'Impossible' became the fastest selling single of the year so far and clearly shows no signs of slowing down anytime soon.

Whether the Justice Collective can improve on their sales is another matter but one thing is for sure- with all the proceeds from both singles going to charity, everyone's a winner.
