Tonight's penultimate results show opens with an emotional group routine from our professional dancers, and we have a brilliant music performance from JLS. Your votes at home have decided who will face the dance-off. It is then down to the judges to decide who will become 2021's Strictly Come Dancing semi-finalists.

Two of the remaining four couples face the last dance-off of the series, hoping to secure a place in the Grand Final. Featuring a guest music performance from Mabel.
