‘Strictly Come Dancing’ is a celebrity-pro ballroom dance competition, which launched on BBC One in 2004. It’s inspired by former BBC show ‘Come Dancing’, and shares its name with 1992 film ‘Strictly Ballroom’. Being one of the most popular shows on TV, it goes head-to-head with ITV’s ‘The X Factor’ from September to December every year on Saturday and Sunday nights. It was originally hosted by Sir Bruce Forsyth and Tess Daly, but Claudia Winkleman has taken over from the veteran entertainer since he stepped down in 2014. The current judges are Len Goodman, Craig Revel-Horwood, Darcey Bussell and Bruno Tonioli, while Alesha Dixon and Arlene Phillips have both previously sat on the panel. The show recently concluded its 13th series, which was won by The Wanted star Jay McGuiness and partner Aliona Vilani, who followed in the footsteps of previous winners like Caroline Flack, Louis Smith, Alesha Dixon, Harry Judd and Abbey Clancy. The 2016 series sees the departure of professional dancers Ola Jordan, Aliona Vilani, Tristan McManus and Kristina Rhianoff, who have all quit the show.
