Chris Hollins would be better than Anton and Vernon - they both have big egos, but all three are not that good at ad libbing, Vernon is awful and just does that stupid smile when he gets stuck, Anton was being groomed to take over but has had enough chances doing many TV programs that all flopped as hes useless.
I think the presenter would have to be someone older and experienced who has done both live presenting and dancing but can't think of anyone... I am going to throw a name in here that maybe nobody has thought of yet.....Claire Balding
I think she is easily the best live TV presenter around and I can see her fitting in easily.
Maybe get rid of Tess as well, and have Chris Hollins doing her job.
