The boss of a Bradford lookalike agency will be doing more than one double take on Sunday - she is one of the judges in a Pop Idol-style contest to find the best dead ringers in Britain.

Danielle Constantine, 29, who runs A-List Lookalike and Entertainment Agency in Greengates, said she was delighted to be chosen.

She won a place on the judging panel after impressing producers of the show with the standard of the 1,000-plus lookalikes on her books. The company was formed less than two years ago.

The show, called Celebrity Doubles, will be filmed on Sunday and broadcast on the Discovery Channel in the autumn. Thousands of hopefuls have sent in videos of themselves and have been whittled down to a hundred.

Referring to hit ITV1 show Popstars the Rivals, which saw former Spice girl Geri Halliwell on the judging panel, Danielle said: "I'm going to be the Geri of this panel. I'm really excited about the show and this is exciting for Bradford too as our agency beat all the others around the country."

Danielle, who has herself worked as a Sarah Jessica Parker lookalike, said: "There is an enormous interest in celebrities and celebrity lifestyles at the moment and people can make a really good living out of it."

Nine winners will be chosen who will all receive health and beauty treatments. One overall winner will get a holiday and a contract with Danielle.
