The book also details the feud between brothers Harry and William, and how their once close relationship disintegrated. In Harry’s book Spare, he claims that the brothers had physical altercations as well as verbal disputes.

Scobie claims that since the late Queen’s death, “absolutely nothing has changed” between Harry and William. He goes on to explain that there is no hope with the two of them reconciling their relationship any time soon.

“I was talking to a source quite early on in the process, and they called Harry a ‘defector’ and said that was William’s view. These were two men who once upon a time were firmly aligned in their outlook.

“One of them had to move on to also protect the crown,” he says in the book. Scobie also alleged that Harry had been “brainwashed by an army of therapists” and Meghan’s complaints had “blindsided the family”.

Prince William reportedly no longer recognises Harry and “doesn’t want to know” him anymore, a source has revealed. The controversial book has been dubbed “a penetrating investigation into the current state of the monarchy”.
