The Duke of Sussex has once again ruffled royal feathers with his recent announcement that he will be publishing his memoirs. In a statement on Monday, he promised readers a "firsthand account of my life that's accurate and wholly truthful.” News of the book has reportedly sparked a "tsunami of fear" in royal circles, as family members brace for potentially further damaging revelations.

       Harry and Meghan have already strained relations with the Firm with their various claims made in interviews with Oprah Winfrey.

       In addition, Harry criticised Prince Charles' parenting skills during an appearance on the Dax Shepard's Armchair Expert podcast.

       Despite all the attacks and criticism directed at the royal institution, the Queen has insisted that both Harry and Meghan remain "much loved members of the family".

       However, Russell Myers argues Harry risks cutting himself off permanently from his family, if he continues a campaign of "score-settling".

       The Daily Mirror columnist writes: "The continued score-settling and personal attacks both he and Meghan have been responsible for in recent months would be enough for any ‘normal’ family to surely cut off contact.

       "Somewhat unbelievably, there still is an appetite to keep Harry and Meghan close.

       "The Queen graciously said they would “continue to be much loved members of the family”, but one does wonder how much more can everyone on the other side of the fence can take.

       "Time will tell whether Harry’s decision will be a welcome one.

       "Get it wrong and he may not be welcomed back ever again."

       The Duke of Sussex revealed he would be writing the book "not as the prince I was born but as the man, I have become," in a statement on Monday.

       “I've worn many hats over the years, both literally and figuratively, and my hope is that in telling my story - the highs and lows, the mistakes, the lessons learned - I can help show that no matter where we come from, we have more in common than we think," he said.

       Harry added: “I'm deeply grateful for the opportunity to share what I've learned over the course of my life so far and excited for people to read a firsthand account of my life that's accurate and wholly truthful.”
