There are two things to add to the voluminous analysis of Boris Johnson’s prime ministerial ascendancy; everyone has heard of him, which is a tribute to his colourful, clever and inspiring personality. Secondly, every pundit is telling you he will be or won’t be a great prime minister.

Honestly, we just don’t know. To succeed he will need steely resolve, good judgment and continue to use his mastery of language. So far, so good. He’s sacked half the May cabinet, which was divided and feckless, and replaced it with people he feels he can trust to deliver Brexit by October 31. That showed steel and it showed good judgment.
