Four previous winners of Strictly Come Dancing are set to go head-to-head in the show's Christmas 

The BBC has announced the star-studded line-up which includes six couples.

The former winners who will be returning are model Abbey Clancy, McFly's Harry Judd, Holby City's Tom Chambers and war veteran Cassidy Little, who won the People's Strictly for Comic Relief.

TV presenter Alison Hammond and radio presenter Lisa Snowdon, who finished in third place, make up the final two.

Professional dancers Pasha Kovalev, Brendan Cole and Robin Windsor will be partnered with the female celebs, while Natalie Lowe, Oti Mabuse and Joanne Clifton will partner the gents.

Sir Bruce Forsyth will return to host the show alongside Tess Daly.

The Christmas special will see the couples performing routines themed around favourites such as Alice In Wonderland, Jack Frost and Scrooge.

There will be added glamour in the form of a performance from Dame Shirley Bassey.

While the judges - Len Goodman, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood - will return to voice their opinions on the performances, the studio audience will decide which couple wins.

The Strictly Come Dancing Christmas Special airs on BBC One on Christmas Day.
