Piers Morgan has blasted Prince Harry after the Duke of Sussex said that the First Amendment is "bonkers".

Prince Harry said in a podcast with actor Dax Shepard that he's "got so much I want to say about the First Amendment as I sort of understand it, but it is bonkers.

“I don’t want to start going down the First Amendment route because that’s a huge subject and one which I don’t understand because I’ve only been here a short time.

“But, you can find a loophole in anything. You can capitalise or exploit what’s not said rather than uphold what is said.”

Morgan, 56, was furious with the royal, saying that Prince Harry was a "spineless whiny crybaby".

“Harry’s gone from being a courageous war hero to a spineless whiny crybaby who blames his family for all his supposed woes and who like his wife, shamelessly and cynically weaponises issues like mental health and racism to silence critics.

“Harry has lost his country, his dignity and now seems to be losing his mind too as he condemns everything from his grieving grandmother to free speech.

“It’s time His Royal Hypocrite stopped abusing his family, stopped moaning about everything all the bloody time, stopped exploiting his royal titles for huge financial gain, stopped trashing America’s constitution – and grew a pair.”

Prince Harry also angered royal fans with his comments about the royal family as he said that he felt like he had to leave.

Harry continued: “Look what it did to my mum. How am I ever going to settle down and have a wife and a family when I know that it’s going to happen again because I’ve seen behind the curtain?

"I’ve seen the business model, I know how this operation runs, how it works. I don’t want to be part of this. Then once I started doing therapy the bubble was burst. I plucked my head out of the sand. I said, ‘You are in this position of privilege.

"Stop complaining, stop thinking as though you want something different. Make this different, because you can’t get out. So how are you going to do this differently? How are you going to make your mum proud? How are you going to use this platform to really effect change’?”
