As King Charles led the Remembrance Day service at the Cenotaph last week, one of the most major events in the royal calendar, Body language expert Darren Stanton said that King Charles’ behaviour in public has significantly changed as he has gotten older and more confident.

“As a younger man in his 20s, he was not very outgoing and extremely introverted," the expert told The Mirror.

Darren Stanton also said that as a consequence, King Charles was unable to bond, connect, and interact with the general world because of which he was a shy which showed through his body language at events.

“King Charles has adopted a number of these gestures probably unconsciously when faced with certain situations over the course of his life, including playing with his cufflinks," the expert said.

“Charles would often do this at social events, which is a clear indication of nerves and self-reassurance," the expert added.

“As the decades have gone on, Charles has improved greatly in his sensory ability and confidence. This can be re-confirmed by a steady decline in the use of these pacifying gestures," he further said.
