Tess Daly and Claudia Winkleman present Strictly Come Dancing, as the battle of the ballroom intensifies.The eight remaining couples will each take to the floor in a bid to impress the judges in the studio and the viewers at home.This week the stakes are even higher, as each couple are not only dancing to stay in the competition but also for the chance to dance on one of the world's most iconic dancefloors when Strictly hits the road and heads to the Blackpool Tower Ballroom next weekend.Once the judging panel of Strictly royalty - Len Goodman, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood - have given their scores, the public will have the chance to cast their votes.The two couples with the lowest combined judges' scores and viewer votes will have to face the dreaded dance-off on Sunday's Results show.
