Following last weekend's show from the sensational Blackpool Tower ballroom, Strictly Come Dancing returns back home to Elstree as the six remaining couples take to the floor.Tess Daly and Claudia Winkleman present, as the battle for the Glitterball trophy really heats up as the remaining couples dance to impress the ballroom bigwigs of Len Goodman, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood with their Ballroom and Latin routines as they face another dance.Plus after performing their individual routines, all six couples will dance a Cha Cha at the same time in the Cha Cha Challenge, which is brand new for 2016 and is where everyone will be hoping to impress the judges for valuable extra points. The leaderboard could be turned upside down at this crucial stage of the competition.Once the couples have performed their routine and taken part in the Cha Cha Challenge, the voting lines will open and it will be up to the public to decide which two couples must face each other, and the judges, to dance for their survival in Sunday's Results Show.
