X Factor winner Sam Bailey's first single Skyscraper is this year's Christmas number one single in the Irish charts.

The singer pushed Lily Allen's cover of Keane's Somewhere Only We Know off the top spot and Ellie Goulding's How Long Will I Love You climbed 12 positions and is now at number 3.

Bailey's video for the Demi Lovato cover was released this morning. She premiered the single at the finale of the singing competition last Sunday night at a live show from Wembley.
