On tonight's results show, our professional dancers mark Remembrance Sunday with a beautiful group number, and the guest music performance is by Sheku and Zak. How will your votes at home change the leaderboard this week? As always, the two couples with the lowest combined judges score and viewer vote will have to face each other in the dance-off. Then it's over to the judges to make the final decision. Who will they take through to Blackpool, and who will they send home?
