X Factor winner James Arthur has topped the charts and scored 2012's fastest selling single with his debut 'Impossible', it's been confirmed.
The track shifted over 490,000 copies across the week, more than three times the figure of 152,000 achieved by the year's previous faster seller, 'Call My Name' by Cheryl Cole.
However, it did not beat the 576,000 sales notched up by Alexandra Burke's 2008 winner's single 'Hallelujah', which went on to become the best selling X Factor single of all time.
Shontelle's original version of the song has also re-entered the chart at number 22, having previously reached number nine in 2010.
Speaking to the Official Charts Company, James said: "I would like to say to everyone from home and around Britain who bought the single, thank you very, very much. You have made my dreams come true."
'Impossible' is the first ever X Factor winner's track to benefit charity, with profits going to children's organisation Together For Short Lives.
Last week's number one, Gabrielle Aplin's version of 'The Power Of Love' - featured in the John Lewis Christmas TV ad - fell to four, with Bruno Mars' 'Locked Out Of Heaven' at three.
