Judi said: “With her dedication to providing a complimentary body language state for her husband when they attend royal visits together, Camilla will tend to use the kind of poses and behaviours that we can see in these shots of them together.

“She will mirror Charles’s posture so that they are slightly hunched together as they are here, or she will often stand to attention to one side, looking slightly awkward and a little wary as she watches Charles take the spotlight while she waits for her cues.”

Camilla looked more relaxed in pictures when she and Charles were apart, Judi claimed.

The analyst added: “It is also clear from this set of photos though that she is not averse to relaxing a little more and even sharing a joke or laugh when she is not being half of a royal double act.”
