With the X Factor winner's single - in this case James Arthur's 'Impossible' - once again shifted a week earlier to avoid the 'Good vs. Evil' battle of recent years, the top spot is open to anyone who can drum up enough support.
Until recently, the favourite to win the race was The Justice Collective with a cover of the Hollies' 'He Ain't Heavy, He's My Brother', which features vocals from Paul McCartney, Robbie WIlliams, Paloma Faith, Holly Johnson and Melanie C.
Proceeds from the single will be donated to charities associated with the Hillsborough disaster.
However, early figures from the Official Charts Company have revealed that Arthur is currently in the lead, having shifted over 76,000 copies by Monday evening.
