Prince Harry has been warned not to become a “one-trick pony” as his attacks on the Royal Family continue.
Harry released his controversial memoir Spare in January in which he made a number of claims against the Royal Family.
In one of the biggest bombshells in the book, Harry accused Prince William of physically attacking him.
Prince Harry alleged the Prince of Wales grabbed him by the collar and ripped his necklace before knocking him to the floor in 2019.
A former royal correspondent claimed Harry is "determined" Spare will not be his last word.

Elsewhere, he says he believed his father feared MeghanMarkle had the potential to “dominate the monarchy".
Now, a former royal correspondent has claimed Harry is “absolutely determined” that Spare will not be his “last word”.
Nicholas Owen said: "He's obviously determined that the book shouldn't be the last word.
"This touches frankly on one of the most important things I think about, Harry, Meghan and everything else, what are they going to do next."
Speaking to Sky News Australia he continued: "It's all very well spilling out all that stuff, how angry you are with your family and how miserable your childhood has been and all that stuff.
"But, you know, if you're not careful, you're going to be a one-trick pony.
"You've got to find something else to tell the world, some other way to make money."
Last week, it was claimed that Harry and Meghan are eager not to speak more in public about their relationship with the monarchy.
