Whoever becomes the next director-general of the BBC should take a close look at last week’s Question Time. It came from Liverpool, which is perhaps the most left-wing city in the country, Brighton excepted. On it, the actor Laurence Fox was making sensible comments about the Harry and Meghan business (which is beginning to bore me into a stupor), when he was upbraided by a third-division academic from a glorified teacher training college.
