Tonight all of the Strictly couples will take to the dance floor for the second time, and the pleasantries are officially over now as this is the first week that a pair will be voted out. Tess Daly and Claudia Winkleman present the first live show of the series, as the scores awarded to the 15 couples in the previous round are added to those given out following tonight's performances, with JLS star Aston Merrygold currently top of the leaderboard. These combined scores will determine which contestants could be facing the boot tomorrow evening. Ultimately, though, the decision will lie with viewers at home, who are given a chance to have their say via a public vote.
