Tess Daly and Claudia Winkleman invite you to join them for an evening of glitter and glamour. The competition intensifies as our 12 remaining couples hit the dance floor and do ballroom battle to stay in the running for the glitterball trophy. Voting lines will 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 in the dreaded dance-off in Sunday night's results show.
