Tess Daly and Claudia Winkleman welcome viewers to the semi-final results show. The judges' scores and public votes have been combined, and the two couples with the lowest scores dance off against each other, before four couple become three. Featuring a routine by the professional dancers and a musical performance by Sting.
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.
