Mm, I'm not sure about what is going on. The BBC weren't going to investigate, now they are evidence gathering. I think his position was now untenable on the show - he would be scrutinised (rightly or wrongly)whatever he did. I am not passing judgement on whether he was a bully or not, as I don't think we will ever really know for sure what went on in the rehearsals when cameras weren't rolling.

He won't be the first coach to be accused of bullying behaviour to get the best out of their trainees.
