In the series semi-final, the five remaining Strictly couples each perform two routines, as they hope the judges and viewers will grant them a place in the grand final.

Tess Daly and Claudia Winkleman host the final of the pro-celebrity contest, which sees the last four couples perform a dance chosen by the judges, their showdance and their favourite routine from the series. The people with the paddles - Shirley Ballas, Craig Revel Horwood and Motsi Mabuse - will critique each performance, but it will be up to the viewers alone to determine who will be taking the glitterball from reigning champion Kelvin Fletcher. There'll also be a performance by pop superstar Robbie Williams.
