The remaining nine couples take to the dance floor for the first time in a bid to impress the judges. Who will surprise, who will impress and who will be worried that their stint on Strictly could be short-lived? No-one leaves this week, as there is no public vote, but the judges scores will be carried over to the following weekend when the viewers will be able to choose their favourites. The show opens with a spectacular group performance to Burt Bacharach classic What the World Needs Now, where the entire Strictly cast is joined by all generations of dancers to launch the new series in style. Tess Daly and Claudia Winkleman host the weekend's dance extravaganza.
