It is the spookiest event in the Strictly Come Dancing calendar as this year's Halloween special sees the return of spiders, witches, broomsticks and ghosts to the Strictly ballroom. If the celebrities thought the dance floor was scary before, they are in for an even bigger fright tonight! Tess Daly and Claudia Winkleman present what promises to be a spine-tingling show, and the remaining eleven couples enter into the spirit of Halloween. Deciding who has cast the best spell of the evening are judges Shirley Ballas, Darcey Bussell, Bruno Tonioli and Craig Revel Horwood, who will score the remaining couples. Lines open at the end of the show, when viewers can vote for their favourite.
