What's the most unwanted Christmas gift this year?

The X Factor winners' single, that's what!

Little Mix’s single Cannonball (a cover of the Damien Rice song) has sunk like its namesake.

According to a poll by the British Heart Foundation, asking people to reveal their least wanted Christmas present, twenty-five per cent of those surveyed said the X Factor 2011 winners’ single was the gift they’d least like to receive.

Despite winning this year’s X Factor, Little Mix sold only 210,000 copies of their song during its first week of release. While final figures will be higher, the group look set to record the second lowest sales of a winner's single since The X Factor's inaugural year, 2004, when Steve Brookstein shifted just 128,000 copies of Against All Odds.

Little Mix also have the dubious honour of being only the third X Factor winners not to claim the Christmas number one spot. They were outsold by five-to-one by The Military Wives Choir. Go, Gareth!
