It's way too soon for me to think about it really, but I want Keo Motsepe and Gordana Grandosek in as pros (in favour of Robin and Ola, natch).
Slebs-wise, maybe some of Lesley Nichol (Mrs Patmore from Downton and quite a likely choice, I should imagine), Hannah from S Club (now they're officially big again, and we're pretty thin on pop stars who could do it), Greg James, Max Chilton (the F1 driver who is essentially jobless after Marussia went bust), Michelle Collins, my dearly beloved Helen Skelton and Nitin Ganatra from EastEnders and just about every light entertainment show at the moment.
