S14, E4: Join Tess Daly and Claudia Winkleman for a sparkling spectacular as all 15 couples hit the dance floor together for the first time. Every step counts as the judges' scores from last week are combined with those from tonight's show. The celebrities are dancing for survival as the two lowest scoring couples will face the dreaded dance-off in Sunday's results show. The pressure is on. No-one wants to be the first to leave the competition.
