This photograph has now been used in the souvenir programme for the upcoming Coronation, which many believe to be an olive branch from the King to his son and daughter-in-law.
Judi James, a professional body language expert, spoke exclusively to Express.co.uk to explain why King Charles may have chosen this specific photograph for his souvenir programme.
She claimed: “This is an interesting choice of photo with an overall message that leans heavily towards family unity and affection.
“It suggests a desire and optimism for a return to a loving core of the UK monarchy that includes both Charles’s sons and their wives and children.

“It shows Charles as primarily a fond and hands-on grandpa, surrounded by people he loves and who love him.”
Judi noted that the photographer Chris Jackson took many pictures on this occasion, but King Charles chose this specific photograph for the souvenir programme.
She explained: “Taken from the batch of photos from this session it also seems to want to create a very even-handed, idealised view of the family group.”
Some of the photos, according to Judi, “favoured the Waleses”, which may explain why the King chose this specific picture for his Coronation souvenir programme.
Judi added: “Harry and Meghan are very much integrated here.
“Whereas, there were some photos taken on the same session where Louis leans to grab his grandpa’s face and the attention seems to favour the Waleses end of the pose.
“If we unravel the individual body language messages here there seem to be some powerful undercurrents, too.
“Firstly from Meghan, who looks relaxed and happy and is even leaning forward to suggest a strong desire to be a very willing part of this family group.”

“The body language signals seem to go further than just an extended and offered hug from Charles to his sons.”
This souvenir programme shows that the Duke of Sussex can still have a “loving family”, according to Judi.
She claimed: “It seems like a huge hint that Harry should look at the good times and be aware that what he is missing in terms of a loving family is still on offer and could be re-built.
“It is as though Charles has thrown his hat into the ring in terms of reconciliation, leaving it to Harry to make the next move.”
