A quick wikipediaing suggests climate change denial which is disappointing but I can live with it. Plus something about Strictly and accusing a dancer of faking an injury. Is that it?
It's mainly the climate change denial that annoys me as a lot of kids got their love of science and maths from him. However, I find the complaining about CRB checks to be a concern - I can't see any reason why he'd object to them.
Because if you were on Operation Yewtree, you'd for sure have had a look at his history. The fact that they've found nothing indicates the man is clean.
