Entertainment: Strictly Come Dancing – It Takes Two, 6.30pm, BBC2

This year’s 15th series is proving to be a good one but sadly we have already had to say goodbye to popular celebrities Aston Merrygold and Brian Conley as well as dancers Karen Clifton and Brendan Cole. Tonight, though, Zoe Ball (right) is joined by the latest couple to be voted out by the judges after the dance-off and there is analysis of the choreography on display in the weekend’s performances.
