Tess Daly and Claudia Winkleman present the Strictly Come Dancing grand final. Fifteen couples started the competition, and now there are just four couples left, all hoping to win the Glitterball Trophy - and each of the couples must now dance three times. Firstly the judges pick a dance from the series which they think the couple can improve upon. Next the couples each perform their showdance - with no rules and any style, it is their chance to showcase their creativity and dancing skills. And finally, each couple dance their favourite routine from the series in a bid to be crowned winners. The fearsome foursome of Bruno, Darcey, Craig and Shirley critique each performance, but it is up to the viewers alone to vote for their favourite. Who will the viewers choose as their Strictly champions of 2017? There is also music from Ed Sheeran.
