Strictly Come Dancing returned for its eleventh series beginning with a launch show on 7 September 2013, and the live shows beginning on 27 and 28 September 2013. Sir Bruce Forsyth and Tess Daly returned to co-present the main show on BBC One, with Claudia Winkleman presenting the results show alongside Daly. Zoe Ball returned as presenter of ' on BBC Two. Darcey Bussell, Len Goodman, Craig Revel Horwood, and Bruno Tonioli also returned as judges.
This was the first series to be made at Elstree Film and Television Studios in Elstree, Hertfordshire. In March 2013, the show's former home at the BBC Television Centre in West London closed down for redevelopment. Strictly Come Dancing moved to Elstree for the series and settled into the vast George Lucas Stage 2 which had been recently refurbished. The move to the Elstree location saw a complete overhaul of the look of the show with a newly redesigned set.
The shows on 5 October, 9 November, and 7 December 2013 were hosted by Daly and Winkleman, with Forsyth taking time off. The show was broadcast live from the Blackpool Tower Ballroom on 16 November 2013.
Abbey Clancy and Aljaà ¾ à  korjanec were announced as the winners on 21 December, while Coronation Street actress Natalie Gumede and Artem Chigvintsev and BBC Breakfast presenter Susanna Reid and Kevin Clifton were the runners-up.
The couples dance each week in a live show. The judges score each performance out of ten. The couples are then ranked according to the judges' scores and given points according to their rank, with the lowest scored couple receiving one point, and the highest scored couple receiving the most points (the maximum number of points available depends on the number of couples remaining in the competition). The public are also invited to vote for their favourite couples, and the couples are ranked again according to the number of votes they receive, again receiving points; the couple with the fewest votes receiving one point, and the couple with the most votes receiving the most points.
The points for judges' score and public vote are then added together, and the two couples with the fewest points are placed in the bottom two. If two couples have equal points, the points from the public vote are given precedence. As with the previous series, the bottom two couples have to perform a dance-off on the results show. Based on that performance alone, each judge then votes on which couple should stay and which couple should leave, with Len Goodman, as head judge, having the last and deciding vote.
On 1 June 2013, it was revealed that Erin Boag, Flavia Cacace, Vincent Simone, and Aliona Vilani would all be leaving the show. They were replaced by four new professionals: Iveta Lukoà ¡ià «tÃÂ, Janette Manrara, Aljaà ¾ à  korjanec, and Emma Slater. However, on 22 August 2013, it was announced that Slater would move to the Dancing with the Stars and that she would be replaced by Anya Garnis. It was also confirmed that Kevin Clifton would join the show, bringing the total number of couples to fifteen. On 2 September 2013 it was reported that professional dancer Natalie Lowe had injured her foot and would be replaced by Aliona Vilani.
This series featured fifteen celebrity contestants. The full line up was revealed on The One Show on 2 September 2013. The celebrities did not know their professional partners until they were introduced to each other on the launch show on 7 September 2013.
