It's the 127th single to reach the UK sales milestone

‘Impossible’, the debut single by James Arthur, has passed the million sales mark in the UK, reports The Official Charts Company.

The news places X Factor winner Arthur in an elite group – ‘Impossible’ is only the 127th single to surpass a million sales in the history of the UK’s Official Singles Chart.

In the short time since its December 2012 release, Arthur’s single has been Number One twice – it was knocked off the top spot by The Justice Collective’s charity single ‘He Ain’t Heavy, ‘He’s My Brother’, and missed out on the coveted Christmas Number One spot, returning to the top place on December 30.

‘Impossible’ is now the fourth biggest-selling debut single by an X Factor, and is expected to topple the third best-selling, Matt Cardle’s ‘When We Collide’, by Sunday (January 13). Alexandra Burke’s ‘Hallelujah’ and Shayne Ward’s ‘That’s My Goal’ are the show’s biggest selling debuts – so given their career trajectories, Arthur had perhaps best not get too comfortable at the top.
