Commenting on other recent outings, body language expert Judi James explained Kate is likely to continue taking a leading role in the family.
The expert stated: “Although the Queen shows no sign of slowing down with age it does appear that – with Camilla never really taking a totally pivotal role in royal life – Kate is increasingly seen as a future leader in the family.
“Kate’s non-verbal signals suggest raised levels of confidence recently.
“She appears to be moving into a more high-profile royal role in her own right.
“Kate’s role has grown slowly and carefully and she appears to be a rule-keeper who could evolve into a rule-enforcer once she is Queen, protecting protocol and maybe even acting as mediator in the family but without becoming stuffy or unapproachable.”
The expert explained her body language has shown she will likely step up to enforce rules in the future.
However, Judi claimed it is unlikely she will make any changes in the family and simply stick to protocols already in place.
She said: “What I don’t think Kate will be as Queen is a massive moderniser and changer.
“Her roles as wife and mother seem dominant, unlike some of the royal women who excel in other careers.
“I’d imagine her focusing on the very traditional path of charity work but without any of the staunch campaigning or ground-breaking and often controversial paths taken by Diana before her.”
Instead of striving to make change, the mother-of-three has been a “calming and stable” influence among the royals.
Since taking on a working role, Judi suggested Kate has not made any mistakes in terms of what is expected of her.
The expert claimed she has avoided any “criticism” and negativity.
“So far Kate has not put a foot wrong in terms of her royal role,” Judi continued.
“Her styling and her body language are impeccable and – in a world where royals, like celebrities, are chopped down to size on a regular basis – she appears able to avoid anything other than petty criticism.
“We see very little if any displays of emotions other than positive ones from her in public and, with their touch rituals at a minimum, we are shown little if any glimpses into her relationship with William other than the happy, positive and loving traits.”
