Joe McElderry spoke of his delight after bouncing back from his Christmas charts heartache to clinch the New Year No 1.
After missing out on the festive top spot to Rage Against The Machine after a high profile internet campaign, the X Factor champion hit back by selling more than two-and-a-half times more copies than its rival last week.
The Climb sold 196,000 copies in its second week, compared with 69,000 copies shifted by Rage Against The Machine's Killing In The Name, which slipped to second spot.
Lady Gaga's Bad Romance held onto third spot, while Cheryl Cole - McElderry's mentor from the series - enjoyed another festive boost as her single, Three Words, climbed from seventh to fourth.
3OH!3, featuring Katie Perry, and Black Eyed Peas took fifth and sixth positions respectively with Starstrukk and Meet Me Halfway.
Journey, Rihanna, Robbie Williams and Kesha completed the top ten.
McElderry, on being told the news, said he was "so happy".
The South Shields teenager said: "I am so happy that the single is No.1. Thank you so much to everyone that has supported me, this had been the best Christmas ever and I want to wish everyone a very Happy New Year."
In the album charts, Canadian crooner Michael Buble was celebrating as Crazy Love replaced Susan Boyle's I Dreamed a Dream as the week's best-seller.
Black Eyed Peas came in at third, while The Fame by Lady Gaga held on to fourth.
JLS's debut album remained at five, ahead of Reality Killed the Video Star, by Robbie Williams.
