Royal biographer Angela Levin has labelled Prince Harry and Meghan Markle "extremists" during a furious rant about the couple.The royal writer slammed the pair for their behaviour and conduct towards the Royal Family during an interview on GB News.The expert expressed her fury Live on TV and said: "Anybody who actually admires the way that Harry and Megan are behaving are extremely wrong and should be ashamed of themselves." Levin continued: "I think psychologically, they've cracked open something, that other people think ‘well, I wouldn't want to do what they're doing because they're extremists and they behave very badly, but there must be some way of earning more money out of that’." The stern faced critic went on to accuse Harry and Meghan of trying to make money out of their ties to the Royal Family, but have no respect for it. Angela's criticism of the Duke and Duchess of Sussex raged on: "That's another reason why they should be so ashamed of themselves because it's just not right.
