Prince Harry has shocked fans and the royal family with his latest announcement, as he plans on publishing a tell-all book about his life.

Penguin Random House made the announcement, saying it was "honoured" to publish the memoir by the Duke of Sussex.

“In an intimate and heartfelt memoir from one of the most fascinating and influential global figures of our time, Prince Harry will share, for the very first time, the definitive account of the experiences, adventures, losses and life lessons that have helped shape him,” it said.

“Covering his lifetime in the public eye from childhood to the present day, including his dedication to service, the military duty that twice took him to the frontlines of Afghanistan, and the joy he has found in being a husband and father, Prince Harry will offer an honest and captivating personal portrait, one that shows readers that behind everything they think they know lies an inspiring, courageous and uplifting human story.”

Prince Harry confirmed the news, saying he was excited to share his life in a way that was "accurate and wholly truthful".

“I’m writing this not as the Prince I was born but as the man I have become,” he said.

“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.

“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.”

Markus Dohle, the CEO of Pengiun Random House, said the company was “thrilled” to be releasing the book.

“Prince Harry has harnessed his extraordinary life experience as a Prince, a soldier, and a knowledgeable advocate for social issues, establishing himself as a global leader recognised for his courage and openness,” said Mr Dohle.

“It is for that reason we’re excited to publish his honest and moving story.”

However, the announcement wasn't without its critics.

Piers Morgan led the charge, tweeting "You've got to be f---ing joking?????"

"Oh Harry, leave the ghost-written autobiographies to the footballers. Your Granny hasn't felt the need to tell 'her story' having lived three times as long as you," GB News presenter Colin Brazier tweeted.

Royal biographer Robert Jobson wrote, "I'd say the Windsor Christening of 'Lilibet' with the Queen present might well be off! Unless 'H' intends to combine it with a book signing tour of the UK that is…"

Random House hasn't confirmed how much Prince Harry will be paid for his memoir but Prince Harry says that he will be donating the proceeds to charity.
