I didn't see it but would point out that it was our, female, Bishop of Newcastle who pushed for him to go. He was shoehorned into Durham, briefly, in preparation for Canterbury.
With regard to safeguarding, those of us involved at parish level are now obliged to undertake safeguarding training and know when to report concerns to safeguarding officers and on up the line. I think, perhaps, those in more senior positions haven't had the same training and don't know what to do when a problem occurs (more so in the past). They need strict guidelines as to the correct procedures, the same as the rest of us.
