Tess Daly and Claudia Winkleman invite viewers to join them for a memorable show at the historic Blackpool Tower Ballroom as the remaining seven celebrities battle it out on the world-famous dance floor. The show opens with a special Strictly performance from the professional dancers and celebrities, inspired by Fred Astaire and Ginger Rogers. 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 in the dreaded dance-off in the results show.
