Strictly Come Dancing series 18
Strictly Come Dancing returned for its eighteenth series with a launch show on 17 October 2020 on BBC One, and the live shows beginning on 24 October. Due to the COVID-19 pandemic, the series launched a month later than usual and ran for only nine weeks instead of the usual thirteen. Tess Daly and Claudia Winkleman returned as hosts, while Zoe Ball and Rylan Clark-Neal returned to host Strictly Come Dancing: It Takes Two. Clark-Neal was replaced by Gethin Jones for four shows after coming into contact with someone who had tested positive for COVID-19.
On 12 September, it was announced that for the first time since the tenth series, there would be no live show broadcast from the Blackpool Tower Ballroom due to the pandemic. However, it was announced shortly afterwards that there would be four episodes highlighting the best moments from previous series. The final episode featured a tribute to 2014 winner Caroline Flack, who had died on 15 February that year.
Shirley Ballas, Craig Revel Horwood, and Motsi Mabuse returned to the judging panel. On 21 August 2020, it was announced that Bruno Tonioli could not be part of the judging panel for this series due to travel restrictions imposed by the COVID-19 pandemic and his role on Dancing with the Stars. Tonioli instead appeared virtually to give his critiques on the performances during the Sunday night results show. Motsi Mabuse had to miss weeks 4 and 5 in accordance with British government guidelines after travelling to Germany due to a break-in at her dance academy; she was replaced by professional dancer Anton Du Beke, who had previously been eliminated from the competition alongside Jacqui Smith. Du Beke became a permanent judge from the nineteenth series.
Bill Bailey and Oti Mabuse were announced as the winners on 19 December, while HRVY and Janette Manrara, Jamie Laing and Karen Hauer, and Maisie Smith and Gorka Márquez were the runners-up.
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 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 Shirley Ballas, as head judge, having the last and deciding vote.
Professional dancers
On 6 March 2020, Kevin Clifton announced he was leaving the show after seven years. Despite being confirmed in the 2020 professional line-up, on 26 March 2020, AJ Pritchard announced he was leaving the show after four years. The other professional dancers from 2019 were all confirmed to be returning for the series. Neil Jones and Nadiya Bychkova only featured in group dances after having partners the previous year, alongside Graziano Di Prima and Nancy Xu.Due to the pandemic, several changes had to be made in how the professional dancers performed. Firstly, the dancers had to shield at home for two weeks. They then formed a bubble which allowed them to stay in a hotel, where they could practise their routines. All of the group dances were pre-recorded.
