A royal commentator has claimed that the Queen is trying to "hold back the King" after he has drastically "ramped up" his royal duties.
This comes after Charles presented his eldest son Prince William with the title of Colonel-in-Chief of the Army Air Corps.
Speaking about The King's duties, Jennie Bond said: "They said he'd be carrying out two or three engagements every week. It's at least that now.
"Most of them don't last too long, so they are probably not too tiring. There he was yesterday with his son at the ceremony, the handing over and the garden party, as you say.
"So yes, he's being seen in public as much as he possibly can, but there are slight amendments today. There were about 50 people at the investiture. Normally there'd be 60 or 70.
"Perhaps it was sort of ten, 15 minutes, maybe half an hour shorter than usual. So the doctors I think are monitoring it closely and whispering in his ear, don't get too exhausted.
"We know that Camilla is trying to hold him back a little bit, but we're told he's a bit like a caged lion.
"He wants to get out there, he enjoys it. I mean, he really thoroughly seemed to be enjoying the investiture."
