The remaining couples left in the competition perform live for the last time before this year's champion is announced. After each couple have danced the judges give their verdicts on what they have seen and scores.
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.
