Prince Harry thought he was being "thrown under the bus" while work was done to make his brother William "look good", a new book has claimed.
Finding Freedom, written by Omid Scobie and Carolyn Durand, describes Harry and his wife Meghan Markle's journey and how they have navigated public lige.
And in one section of the book, the writers claim Prince Harry and William's relationship soured, reports Mirror Online.
A source told the book: "Harry was upset that it was playing out so publicly and that so much of the information being reported was wrong.
"There had been moments where he felt people working with his brother had put things out to make William look good, even if it meant throwing Harry under the bus.
"It was a confusing time, and his head was all over the place - he didn't know who or what to believe, and he and William weren't talking enough either, which made everything a lot worse."
The writers claim the brothers' fallout was so concerning, it was openly discussed at a staff retreat last year.
An insider tells the authors: "It's no secret, the future of this monarchy relies solely on the four people currently in Kensington Palace.
"The public popularity only lies with them.
"When he [the Prince of Wales] becomes King, the only way it lasts is if the four of them are not at war. We cannot have them at war."
And the book describes the moment the Cambridges first met Meghan at Kensington Palace - and a moment which they claim angered Harry.
According to their sources, William said: "Don’t feel like you need to rush this" and "take as much time as you need to get to know this girl", reports People magazine.
They write: "Harry was p***ed off.
"P***ed off that his brother would ask such a thing. Some felt it was an overreaction.
"But then, this totally sums them up as people - William the calm and rational one, and Harry, who can’t help but take things far too personally."
