Tess Daly and Claudia Winkleman launch a new series of the celebrity dance contest, pairing up the 15 celebrities with their professional dance partners. 2016 champions Joanne and Ore return to perform their winning jive, and there is music from Shania Twain and Rita Ora.
The celebrities take to the floor for their first group dance, and there is a very special group routine as everyone on Strictly pays tribute to Sir Bruce Forsyth.
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.
