Charles has taken a break from his public duties this week as he prepares for surgery.

Ms. Levin adds: “As Queen Camilla said, ‘He can’t wait to get back to work.’

“He’s quite well in his mind, and he could’ve gone somewhere, but it makes it very awkward, because he has to keep rushing to the toilet. You can’t do that. You’ve got to be dignified. And be able to do it.”
