Sam Bailey is Christmas No.1 but how well did she sell?

Leicester's X Factor winner Sam Bailey has been knocked off the number one spot after just one week in the official charts rundown.

After being beaten into second place last week, Pharrell Williams came back fighting and took over the top position, claiming his third number one hit of the year.

The 36-year-old mother-of-two sold 149,000 copies of her winner's single Skyscraper, a cover of Demi Lovato's hit single, bagging her the Christmas Number One title - albeit with the lowest sales for that week on record.

Meanwhile, Robbie Williams held onto the top spot in the albums chart, despite facing competition from his Take That bandmate and X Factor judge Gary Barlow.

The winner of this year's X-Factor, Sam Bailey, has tweeted that she will be performing at Twickenham as the Harlequins take on the Exeter Chiefs in Big Game 6.

Former prison officer turned X Factor winner Sam Bailey has said achieving the coveted Christmas Number One spot with her debut single 'Skyscraper' was the "icing on the cake".

Bailey told OfficialCharts.com: "Being Number 1 is absolutely amazing.

"It really is the icing on the cake and it means Great Ormond Street Children's Charity and Together For Short Lives will benefit from the single, which makes it extra special."
