Tess Daly and Claudia Winkleman present the fourth live episode of this year's series. Now that Anneka Rice has departed from the dancefloor, the 13 remaining couples hope to impress the judges and the viewers at home with an array of ballroom and Latin routines. Judges Motsi Mabuse, Craig Revel Horwood, Shirley Ballas and Bruno Tonioli will score the performances out of ten before the vote lines open - which gives viewers at home the chance to have their say and determine who will be leaving the competition.
