Prince Harry is facing criticism after he said he wants to "break the cycle" of the "pain and suffering" of his upbringing with his own children.
Royal biographer Angela Levin fumed: "I think he knows exactly what he's doing.
"People keep saying that he's an idiot but I don't think he is. I think he knows exactly what he wants to say and he wants to hurt them to punish them because he feels they have wronged him and they have wronged Meghan.
"The fact they tend to give anything they hear or say to the Royal Family to friends of Meghan's who report it to social media is a way of killing off the bonding and working towards something positive.
"These things are very delicate, you can't repair such terrible damage in sort of 20 minutes especially at your grandfather's funeral.
"They can't trust him anymore. Whatever they say, even if they creep in slowly and gently, if that gets passed on you can't bond you can't heal."
Palace insiders have also been speaking out.
One said of Harry and Meghan "nothing ever appears to be their own fault".
While another source said: "They appear to be making careers of talking about their previous ones. It is not helpful."
The Duke of Sussex, who is expecting a daughter with wife Meghan and is already father to son Archie, aged two, compared his life to “a mixture between The Truman Show and being in a zoo”.
Speaking on the podcast Armchair Expert with Dax Shepard, he said: “There is no blame. I don’t think we should be pointing the finger or blaming anybody, but certainly when it comes to parenting, if I’ve experienced some form of pain or suffering because of the pain or suffering that perhaps my father or my parents had suffered, I’m going to make sure I break that cycle so that I don’t pass it on, basically.
“It’s a lot of genetic pain and suffering that gets passed on anyway so we as parents should be doing the most we can to try and say ‘you know what, that happened to me, I’m going to make sure that doesn’t happen to you’.”
He added: “It’s hard to do but for me it comes down to awareness. I never saw it, I never knew about it, and then suddenly I started to piece it together and go ‘OK, so this is where he went to school, this is what happened, I know this about his life, I also know that is connected to his parents so that means he’s treated me the way he was treated, so how can I change that for my own kids?’
“And here I am, I moved my whole family to the US, that wasn’t the plan but sometimes you’ve got make decisions and put your family first and put your mental health first.”
He compared living under scrutiny as a member of the royal family to the 1998 film The Truman Show, starring Jim Carrey as a man oblivious to the fact that his entire life is a TV show, and to being an animal in a zoo.
He also revealed that he met up with his future wife in a London supermarket in the early days of their relationship and the couple pretended not to know each other.
He said: “The first time Meghan and I met up for her to come and stay with me, we met up in a supermarket in London, pretending as though we didn’t know each other, texting each other from the other ends of the aisle.
“There were people looking at me, giving me all of these weird looks, coming up to say hi or whatever but there I am texting her whilst we’re shopping, asking if this is the right thing and she’s replying ‘No, you want the parchment paper’.
“It was nice with a baseball cap on looking down at the floor, walking along the street and trying to stay incognito.
“Not sure how many times I’ve done that, trying to walk down the street and stay incognito is like ‘whoa signpost, someone’s dog’, it’s amazing how much chewing gum you see and how many shoes.
“So living here (in Los Angeles) now I can actually lift my head and I feel different, my shoulders have dropped, so have hers, you can walk around feeling a little bit more free, I can take Archie on the back of my bicycle, I would never have had the chance to do that.”
