Tess Daly and Claudia Winkleman host the semi-final, in which Emma Barton, Kelvin Fletcher, Chris Ramsey and Karim Zeroual find themselves one step closer to hoisting the Glitterball trophy aloft. As the competition is in its final stages, each couple will now perform not one but two routines in a bid to impress the judges and audience at home. Shirley Ballas, Bruno Tonioli, Craig Revel Horwood and Motsi Mabuse will be on hand to give their penultimate judgement.
