Tess Daly and Claudia Winkleman invite viewers to join them for the semi-final of Strictly Come Dancing. Fifteen couples have been whittled down to just four, with each couple having to perform two dances for a chance to win a place in the Strictly grand final. 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 the results show.
The show pairs a number of celebrities with professional ballroom dancers who each week compete against each other to impress a panel of judges and the viewing public in order to survive potential elimination. Through telephone voting, viewers vote for whom they would like to stay, the results of the poll being combined with the ranking of the panel of judges.
The show is broadcast live on BBC One on Saturday evenings, and is presented by Bruce Forsyth and Tess Daly. The judging panel consists mainly of Bruno Tonioli, Len Goodman and Craig Revel Horwood.
