three of the judges agree that one of the couples should be saved, that couple is through to the following week's competition and the Head Judge's vote is not counted. If one couple has two votes and the other couple has one vote, then the deciding vote is cast by the Head Judge, originally Len Goodman and currently Shirley Ballas. Afterwards, the eliminated couple perform one final dance — sometimes known as "waltzing out of the ballroom". The Monday after their elimination, they appear on It Takes Two to discuss their time on the programme. On two occasions, the dance-off was cancelled; firstly, in series 14, in which one of the celebrity contestants, Anastacia, sustained an injury and was unable to compete in the Dance-off as a result. Under the rules of the show, the couple with the lowest combined total was eliminated. The second occasion in which the Dance-off was cancelled was in Series 20, again due to an injury sustained by Tony Adams. Tess Daly announced on the results show that Adams had decided to withdraw from the competition as a result of being unable to compete in the Dance-off. It Takes Two During the run of Strictly Come Dancing, Strictly Come Dancing: It Takes Two is broadcast each weeknight on BBC Two. The series was previously hosted by Claudia Winkleman but, due to her pregnancy in 2011, she had to leave the series, and was replaced by Zoe Ball, who hosted the show from Series 9 to 18. Rylan Clark-Neal joined as co-host in series 17. In May 2021, it was announced that Ball was to leave the show after 10 years, and on 10 June 2021, her replacement was confirmed to be former professional Janette Manrara. The show features reviews of the performances during the previous Saturday's show and interviews with, and training footage of, the couples preparing for the next show. The judges and other celebrities also provide their opinions on how the couples are progressing. It Takes Two replaced Strictly Come Dancing on Three, hosted by Justin Lee Collins, which ran on BBC Three during the first series. Prior to 2010, BBC Two Scotland aired the programme on four nights only, running its own Gaelic-language programming on Thursdays instead.
