The time has come for a third couple to leave Strictly Come Dancing, as Tess Daly and Claudia Winkleman present the results of last night's public vote and the judges scores.The votes have been counted and the two couples at the bottom of the leader board must perform in the dreaded dance-off to save their place in the competition.The awesome foursome of Len Goodman, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood will then decide which dancing duo will be saved and quickstep into next week, leaving the other couple to waltz out of the competition.Tonight's show will open with the professional dancers performing a group routine to classic tracks from James Brown, while this weekend's musical performance comes from the legendary Madness.Lens' Lens will also again be back to take a look at Saturday night's routines.
