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."
X Factor winner Sam Bailey has won the battle for this year's Christmas number one. The 36-year-old former prison officer sold twice as many copies of her single, Skyscraper, than US star Pharrell Williams in second.
Bailey, 36, who was crowned the winner of the singing contest last week, is splitting all proceeds between Great Ormond Street Hospital Children's Charity and Together For Short Lives, a charity which helps children with life-threatening conditions.
Chancellor George Osborne has agreed to waive VAT on the release.
Leicester singer, Sam Bailey, is expected to be Christmas Number One, when the chart is announced later today.
She has wowed audiences throughout the X Factor competition, and following her win last Sunday, released Skyscraper, which looks to be heading for the top spot over Christmas this year.
