Judi said: “Charles and Camilla’s body language defines such a complimentary double act that it just has to be responsible for the Prince’s signals of relaxed fun, confidence and good-humour recently when they are out together on royal visits.”

The Duchess is “tactful” when it comes to putting her husband, the future king, first, Judi claimed.

She added: “Camilla is incredibly tactful in terms of her non-verbal signals with him, standing either alongside or just behind her husband with her hands clasped in front of her torso in a gesture that deflects all the attention and spotlight onto Charles.”

Camilla’s body language exudes approval for her husband’s work, Judi explained.
