Tess Daly and Claudia Winkleman present the results of last night's viewers' votes and judges scores. The two lowest scoring couples must then compete in a dance-off before Shirley Ballas, Dame Darcey Bussell, Bruno Tonioli and Craig Revel Horwood decide which of them will be leaving the contest. Plus, the Backstreet Boys perform a medley of their greatest hits.
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.
