James Arthur has been cut to scoop the Christmas number one spot by William Hill from an original 11/2 on Sunday morning into 2/1 with the Justice Collective out from 1/7 to 4/11 after it emerged that the X-Factor winner had forged ahead in the biggest chart battle of the year.

“We thought that the Justice Collective would have a considerable lead at this stage in proceedings, but it would seem that James Arthur really does have the X-Factor,” said William Hill spokesman Joe Crilly. “

Christmas number one single: 4/11 The Justice Collective; 2/1 James Arthur; 14/1 Alistair Griffin; 20/1 The Choir; 33/1 Clive Dunn; 40/1 Gabrielle Aplin; 50/1 BAR
