WITHAM wonder Olly Murs was celebrating last night after he shot straight to the top of the charts with his debut single.

The former call centre worker’s song, Please Don’t Let Me Go, had been much anticipated by fans who have waited for the release since he came second in the X Factor talent show last year.

Murs, 26, said: “I’m absolutely over the moon that my debut single has reached number one.

“Especially since I was up against such stiff competition. Thank you so much to all my fans and everyone who bought the single.”

It could be an interesting few weeks ahead for Murs who pledged to pose naked if his single hit the top of the charts.

The 2009 X Factor winner Joe McElderry did not enjoy immediate number one success with his debut song - he was beaten to the top spot by rap metal act Rage Against The Machine.

Taio Cruz’s single Dynamite, which was number one last week, dropped to third position as Katy Perry scooped second place with her new single Teenage Dream.

Eminem’s hit Love the Way You Lie, featuring Rihanna, was in fourth spot while Flo Rida’s Club Can’t Handle Me came in fifth.
