She said: “There’s nothing to suggest a meeting of minds between Charles and Kate.
“When they are seen walking together Charles’s body language suggests he might be at a bit of a loss in terms of easy-going conversation.
“His hand is shoved into his pocket to suggest some feelings of awkwardness and he looks away from Kate with a dipped head and the spatial gap between them will often look quite pronounced.”
When Kate is with her father-in-law, the Duchess of Cambridge seems more formal than familiar, the expert suggested.
“Kate’s body language always looks respectful and careful with her father-in-law,” Judi explained.
“Although her air of polite caution might not resonate with Charles, it is clear she is exactly what he needed as the kind of calming and non-disruptive daughter in law that will help hold the fractured royal firm together by never putting a foot wrong.”
When Meghan Markle joined the Royal Family, she also started working as a senior royal.
Although Meghan and Prince Harry have now stepped back from this role, the Duchess of Sussex has attended many events with Prince Charles in the past.
“There appears to be more tuning in between Charles and Meghan and it is probably true to say they share more personality traits, like a passion for campaigning and even more spiritual thinking.”
Meghan and Prince Charles have both been active in campaigning for things they believe in over the years.
These shared ideas might have helped them form a close relationship after Meghan joined the family.
Who is Meghan Markle? Quick profile
Meghan Markle was born Rachel Meghan Markle, on August 4, 1981 to parents Doria Ragland and father Thomas Markle.
Her father was previously married to Roslyn Loveless and Meghan has two elder half sibling – sister Samantha Markle and brother Thomas Markle Junior.
Meghan’s first television appearance in the USA was in an episode of the medical drama General Hospital in 2002.
She later moved on to roles in CSI, Without a Trace and Castle along with bit parts in Hollywood films including Get Him to the Greek, Remember Me and Horrible Bosses.
Meghan was also a “briefcase girl” on Deal or No Deal – but her most famous role was as Rachel Zane in legal drama Suits, which launched in 2011.
She was written out in the finale of the seventh series when her character got married, which aired in April 2018 – just before she got married herself.
Charity and humanitarian work
Meghan Markle’s career in television has gone hand-in-hand with her support for causes close to her heart.
She wrote about the stigma around menstrual health in an article for Time magazine and was a Global Ambassador for World Vision Canada – with whom she travelled to Rwanda for the charity’s Clean Water Campaign.
And her commitment to gender equality has seen her work with the United Nations – receiving a standing ovation in 2015 for her speech to mark International Women’s Day.
In September 2011, she wed film producer Trevor Engelson, who she began dating in 2004.
But the pair divorced two years later in August 2013, citing irreconcilable difference.
She was in a relationship with celebrity chef Cory Vitiello for almost two years, before they broke it off in 2016 but the two remain good friends.
And in June 2016, she met Prince Harry on a blind date set up by a mutual friend.
Their relationship began in October that year and just over one year later, on November 27, 2017, the pair announced their engagement.
They married on May 19, 2018 at St George’s Chapel in Windsor Castle.
Some have claimed Meghan Markle is the first mixed-race member of the Royal Family.
Historians are still arguing about Queen Charlotte, the wife of King George III.
But Meghan will be the first royal to openly embrace a mixed-race heritage.
She has written about the difficulties of being a biracial actress in Hollywood as she claims she is not black enough for some roles and not white enough for others.
