Join Tess Daly and Claudia Winkleman for the first night in a live dancing double bill as six couples take to the floor for the very first time. There'll be no public vote this week, but the couples still have to impress the Strictly judges, whose scores will be carried over to next week.
Will all those hours in the training room pay off? Whose nerves will get the better of them? And who will be cha-cha-cha-ing their way to the top of the leader board?
Let's start dancing!
