Tess Daly and Claudia Winkleman present the traditional festive edition for Christmas Day, which sees the return of six old favourites from past series. Chizzy Akudolu, Gemma Atkinson, Richard Arnold, Debbie McGee, Joe Sugg and Mark Wright take to the dancefloor to perform special Christmas-inspired routines, with judges Shirley Ballas, Bruno Tonioli, Motsi Mabuse and Craig Revel Horwood giving their thoughts. However, it's down to the studio audience to decide which couple should lift the Silver Star trophy.
