Presenters Carol Vorderman and Esther Rantzen will be among the celebrities competing in the second series of BBC One's Strictly Come Dancing show.
Natasha Kaplinsky, Bruce Forsyth and Tess Daly will present
Also included in the line-up are comic Julian Clary, Olympic gold medallist Denise Lewis and gardening presenter Diarmud Gavin.
Each celebrity will be paired with a professional dancer.
The show's first winner, Natasha Kaplinsky, will present the series alongside Bruce Forsyth and Tess Daly.
Kaplinsky will share the presenting duties with Daly, who is due to give birth in October.
Also among the celebrity contestants will be former child singer and Songs of Praise presenter Aled Jones, athlete Roger Black and motoring correspondent Quentin Willson.
Best of both worlds
Representing the acting world will be Jill Halfpenny, who plays Kate in EastEnders, and Sarah Manners, who plays Bex in Casualty.
The celebrities will have to practise a stipulated ballroom dance and perform it on live TV, with viewers and judges voting on who will be eliminated each week.
Countdown presenter Vorderman said: "I'd been saying to friends how I'd wanted to take dance lessons for some time but couldn't fit it in with work, so this is the best of both worlds."
Home Front in the Garden presenter Gavin added: "I think it'll be great fun and a very disciplined way of getting fit but I'm not sure how good our chances are."
The first series saw celebrities including David Dickinson, EastEnders Christopher Parker and Claire Sweeney take part.
