Strictly Come Dancing is a British dance contest show in which celebrities partner with professional dancers to compete in mainly ballroom and Latin dance. Each couple is scored by a panel of judges. The title of the show is a continuation of the long-running series Come Dancing. The format has been exported to 60 other countries under the title Dancing with the Stars, licensed by BBC Worldwide, and led to a modern dance-themed spin-off Strictly Dance Fever. The Guinness World Records named Strictly as the world's most successful reality television format in 2010. The series is currently presented by Tess Daly and Claudia Winkleman. Bruce Forsyth co-presented the series with Daly until 2014.
