Piers Morgan, claimed that many of Prince Harry's American friends are now "completely done" with the royal couple

 Tom Bower's new book Revenge: Meghan, Harry and the war between the Windsors is due to be released on July 21. 

"It is an astonishing story of a woman who came from nothing and is now a world figure and has trampled on all those others on the way. 

 The victims are keen to talk and they have spoken. And it's a really gripping story" Bower told GB news.

Bower described Meghan as a "very scheming, very clever woman

"This book, may hasten the downward trend, over which I wouldn't be sad at all because they pose a real threat to the royal family." said Bower

Morgan has shared his thoughts on the "threat" Harry and Meghan pose to the monarchy, very often

and advocated for the revocation of their duke and duchess titles

Morgan said. "They're calling the royals' a bunch of callous racists and so on

without producing any hard evidence to support any of these claims and it's incredibly damaging."
