A royal commentator has claimed that the Queen is "stressed" about the amount of work King Charles is doing.
King Charles has been partaking in a number of royal engagements over recent weeks despite undergoing cancer treatment and according to royal commentator Rafe Heydel-Mankoo, Queen Camilla thinks he may be doing a bit too much.
The King has returned to his usual work after the Palace announced he would return to public-facing duties on April 30.
Last week he hosted a garden party for 7,000 people at Buckingham Palace, and on Monday he visited an army base for an emotional joint engagement with his son, Prince William - where he handed over a key military role to him.
Speaking on GB News Heydel-Mankoo said: "The Queen has said that if he behaved better, he'd be improving far more rapidly.
"I think she might be a bit stressed at the number of activities he's done I mean, just in the last week he went to Middle Wallop in Hampshire to an air base to hand over to Prince William, the colonel in chief of the Army Air Corps.
"He has hosted a garden party for 4000 people from the creative industries.
"He's attended a service at Saint Paul's Cathedral for the order of the British Empire, and he made a surprise visit to the Royal Opera House on Thursday, where he seemed to be in very good spirits too.
"So I think we should all take some good heart from His Majesty. This is clear progress."
Buckingham Palace confirmed “forthcoming engagements will be adapted where necessary” to accommodate for the King’s recovery following his cancer treatment.
King Charles, Queen Camilla and Prince William will also commemorate the 80th anniversary of D-Day from June 5 to 6.
Heydel-Mankoo revealed that it is "unlikely" that the Princess of Wales will attend the event as she recovers from her own cancer diagnosis.
He said: "Last year she was there, resplendent in a green dress and we're waiting to see whether she will also be attending this time or not.
"But there's been no mention of her attending the D-Day ceremonies, although the Prince of Wales will be attending the Canadian beach Juno, and also at the Omaha Beach, where the international heads of state, but no word of the Princess of Wales attending that.
"So I think it's rather unlikely we'll be seeing her at Trooping the Colour."
Buckingham Palace confirmed the King will also visit the British Normandy Memorial at Ver-sur-Mer and a commemorative ceremony for fallen Canadian soldiers.
A palace source last month stressed the public should not expect to see a “full summer schedule” from the monarch.
During a garden party in Rye, East Sussex, on Thursday, Queen Camilla said the King is "getting better" but joked: "Well, he would be if he behaved."
