The X Factor's Sam Bailey has scored the 2013 Christmas number one with her winner's single 'Skyscraper'.
The star - who was crowned this year's X Factor champion last Sunday (December 15) - shifted 149,000 copies of the single to beat Pharrell Williams and Leona Lewis to the top spot.
Profits from sales of Bailey's debut single will be split between Great Ormond Street Hospital Children's Charity and Together For Short Lives.
On topping this year's festive countdown, 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."
Martin Talbot, chief executive of the Official Charts Company, commented: "Congratulations to Sam Bailey, the UK's Official 2013 Christmas Number 1! X Factor winner one weekend, Christmas Number 1 the next.
"Life can't get much better than that, especially when you have taken the crown with one of the biggest weekly sales totals of the year."
Pharrell Williams is at number two with 'Happy', which is taken from the Despicable Me 2 Soundtrack, while Leona Lewis's Christmas single 'One More Sleep' sticks at three this week.
Meanwhile, AC/DC have scored their first ever UK Top 10 single with 'Highway To Hell', which was supported as part of a social media campaign to prevent this year's X Factor winner from topping the festive chart.
The track is at number four after selling 43,000 copies.
