Strictly Come Dancing is introducing a new Instant Dance challenge that will test the remaining couples like never before. Set to take place on Saturday 29 November, the twist will see each pair randomly select a dance style from those they have already learned this series.
After picking their style, the couples will hear their accompanying music and have just 10 seconds to decide their routine. A frantic dash to wardrobe for a quick costume change adds to the pressure, before they perform the dance on the night.
All six couples will take part in the challenge, which will be judged by the panel. The judges will rank the performances and award extra marks accordingly, with the top couple receiving six points and the lowest receiving one point.
Head Judge Shirley Ballas commented: 'Instant Dance has the power to change everything for our couples, and will challenge them in ways they have never been challenged before. With standards so incredibly high this year and the competition so close, there's a lot resting on it.'
The Instant Dance will take place towards the end of the live show, after all couples have performed their usual routines. The dance styles, costumes and music will remain a secret until the night, adding an element of surprise for both contestants and viewers.
