Kate Middleton and Camilla Parker Bowles reportedly share a key similarity with each other that Meghan Markle doesn’t have.

Royal author Anna Pasternak told Yahoo’s “The Royal Box” that Middleton and Camilla have both adhered to the royal code, which is to keep quiet and not to bleat through friends to the press, not to press their cases in the press, and to get on with where they are in the royal family.

Pasternak also said that Markle is very different from Camilla and Middleton because it seems that she wants to do a lot of things to the monarchy even if her position doesn’t necessarily allow her to do so.

“I think that William is very responsible and, as I said, knows what his role is. And Kate has come alongside that and executed that extremely well… I think it’s quite difficult to have had Meghan, who seems to want to modernize and set her own agenda, and you can’t have it all,” she said.

The royal author stressed the fact that Markle could not have her freedom and the privilege of being a part of the royal family at the same time.

Meanwhile, Markle and Middleton also made headlines this week after it was revealed that the former and Prince Harry have adopted an intimate move from the Duchess of Cambridge.

In the ITV program “Secrets of the Royal Babies: Meghan and Harry,” the narrator said that the Duke and Duchess of Sussex could ensure their child’s privacy by reducing its exposure to the media.

“One way that Harry can protect his child’s privacy is to follow a much more intimate style of portraiture, adopted by his sister-in-law. A lot of the time now Kate takes her own pictures, and she sends them to the media, and we get them that way,” a royal expert said.

Prince Harry and Markle will welcome their first child sometime at the end of this month or the first week of May.
