E2 seems to have a natural wisdom, but she's also a very experienced queen who has played the same role since the 1950s.
A lot of continuity there, while prime ministers come and go. We lose a lot when her reign ends.
I hope the anti-Camilla-because-she's-not-Diana time has passed. It looks like it to me. Camilla's a good fit for Charles and a good fit for the throne, for which a lot of discretion is the name of the game.
