It's Saturday night, and that can only mean it's Strictly time! Tess Daly and Claudia Winkleman invite you to indulge in an evening of sequins and sparkles, as the 10 remaining couples hit the dance floor for a ballroom battle to stay in the competition.Voting lines open at the end of the show; once the judges' scores have been added to viewer votes, the two lowest-scoring couples will perform again the dreaded dance-off during Sunday's results show.
