King Charles does not want to be around drama in his life, says an expert.
His Majesty, who is a big supporter of slimmed down monarchy, wants a civilised Christmas celebration around close family.
Speaking to ReachPlc, former Royal butler Hugh Grant said: "Charles gets on well with them, they get on with their cousins, and they have done nothing wrong.
"As I've said previously, Charles dislikes drama and fallouts. He hasn't fallen out with his nieces, so there's no reason to exclude them. In fact, inviting them may be his way of showing support: Andrew may be stepping back, but his daughters are still part of the wider family."
Earlier in his book, Harrold shared: "I had a conversation [with him] and he explained to me about [the] titles, he explained to me about why you bow and curtsey, and he explained to me about the different titles he could use.
"And we, myself and other colleagues, discussed it and we were all convinced he would [become] George VII. With his grandson George, maybe he felt he should be the next George VII.
This comes after photographer Chris Jackson praised King Charles for his consistency despite cancer treatment.
“There have been challenges in recent years,” Jackson said, referencing the transition after Queen Elizabeth’s passing.
“Seeing how the King and Princess Catherine bounced back from difficult times has been incredible.”
