Tess Daly and Claudia Winkleman reveal the two couples facing each other in the dreaded dance-off and the fabulous judges Shirley Ballas, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood then have to decide who will be waltzing into next week and who will be leaving the competition for good. There is a musical performance from Andrea Bocelli and his son, Matteo, plus a special Remembrance Day group routine from the professional dancers - a tribute to the women who have served in the RAF.
