Perhaps I should stress from the get-go that I do not know Rishi Sunak. So far as I know, we’ve only met once, some years ago when he was working at the think-tank Policy Exchange. He showed me to my seat when I arrived late for an event. It is one of those things you must get used to in this life – that the person you last saw helping you into a folding chair will just a few years later be Chancellor of the Exchequer.
