Strictly Come Dancing series 13

Strictly Come Dancing returned for its thirteenth series on BBC One with a launch show on 5 September 2015, and the live shows beginning on 25 September 2015. Tess Daly and Claudia Winkleman returned to present the launch show and the live shows while Zoe Ball returned to present Strictly Come Dancing: It Takes Two on BBC Two. Darcey Bussell, Len Goodman, Craig Revel Horwood, and Bruno Tonioli all returned as judges.

The Wanted singer Jay McGuiness and Aliona Vilani were announced as the winners on 19 December.

Format
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.

Professional dancers
On 23 April 2015, the list of professionals who were returning for the thirteenth series was revealed. Professionals from the previous series who did not return included Trent Whiddon and Iveta Lukosiute. Robin Windsor, who had not taken part in the previous series due to an injury, did not return for this series, though he would be involved in the spin-off show It Takes Two. Joanne Clifton was also involved in It Takes Two and appeared in the 2015 Children in Need and Christmas specials. Three new professional dancers were introduced: Russian dancer Gleb Savchenko, Italian dancer Giovanni Pernice, and South African dancer Oti Mabuse.

Couples
This series featured fifteen celebrity contestants. On 10 August 2015, broadcaster Jeremy Vine was the first celebrity announced for the series, with more celebrities revealed throughout the month. The lineup was fully announced on 27 August 2015 on The One Show.
