There have been 97 Archbishops of York so far. I learned that from this morning's Sunday. No.97, John Sentamu, has recently announced that he will retire in June 2020. William Crawley discussed the matter with the Bishop of Norwich Graham Jones - and, no, he didn't introduce him with the words, "And now from Norwich, it's the bishop of the week". (That's for anyone who remembers Sale Of The Century). William asked the 'very BBC' questions: Has John Sentamu been "a trailblazer for other BAME clerics"? And is it time for a woman next?
