Allen's cover of Keane’s Somewhere Only We Know, which features in the John Lewis festive TV ad campaign, returned to the top of the singles chart last Sunday to enjoy its second non-consecutive week at the summit.
But with less than 7,000 copies currently separating the top four entries, it could all change come Sunday.
According to OCC midweek sales data, Ellie Goulding’s official Children in Need single How Long Will I Love You has climbed four places to rest at number three.
Meanwhile, former X Factor winner Leona Lewis’ track One More Sleep has rocketed 34 places to number four following her performance on Sunday’s results show.
Avicci completes the top four, climbing six places to number two with his latest single Hey Brother.
The official christmas number one will be called on Sunday 22 December.
