Nice. But I still think it’s silly to call him the most powerful man in the country.
Certainly it's not accurate - but I would call him one of the most influential if he chooses to be. He's just very selective about where he uses that influence.
Once when I challenged him on the issue of climate change, he told me about all the people he'd discussed it with recently. I was a bit surprised - but then I realised that he can probably phone up virtually anybody in the UK, almost anybody in the Commonwealth, and a fairly large number of people in the rest of the world as well, and they'd at least take his call and talk to him.
