Derry singer Nadine Coyle has revealed why Girls Aloud split up after a successful ten years. 

Speaking to the Sun newspaper at the launch of her solo career with Virgin EMI,  she said that the girl group was "fine at the start but that there's always politics in a band."

Nadine, who has released new song Go To Work, said that she got: "more vocals than everybody else, so in terms of people wanting their voice heard, that wasn't happening. It made people, very bitter. They didn’t like that."

Coyle added that: "It's so sad for me to have to admit this stuff now because for so long, there's the band, and you want everybody to think we're best friends.

"That's what I wanted it to be. I really, really wanted that to be, but it just wasn't how it was. We're all very different characters."

Bandmates - Cheryl, Kimberley and Nicola are still on good terms

Since the split, bandmates Cheryl, Kimberley and Nicola have remained close friends in the public eye but Nadine and Sarah Harding have not been seen out with their former bandmates.

Harding recently won Celebrity Big Brother after hinting at a rift in the band while in the house.

Coyle first became known in Ireland in Irish Popstars when she was a teenager.
