Sophie, Countess of Wessex shows

This may have helped the royals establish a respectful relationship with each other.

Judi also suggested Sophie is on hand to offer advice to Kate and look out for the Duchess of Cambridge.

“Many of the poses of the two women together show Sophie face-checking Kate with quite strong bouts of watchful-looking eye contact to suggest she’s taking a semi-maternal approach,” Judi continued.

“Although we normally only seem to see these two royal wives together at more formal events, the body language signals between them show high levels of mirroring and focus on one another that hint that Sophie might have dropped gently and discreetly into place as the royal mother-in-law that Kate never had.”

In the past, the royals have stood together at the Cenotaph at Remembrance Sunday service.
