The British royal family has been on alert once again after Prince Harry's latest announcement of a tell-all memoir.

The Daily Mail reported that the royal family has “very real fears” that the Duke of Sussex’s latest move could very well “destabilize the monarchy” once and for all.

It was revealed that the book by the duke could stir trouble for his father Prince Charles in taking up the throne following the death or abdication of Queen Elizabeth.

The royal family's qualms intensified over reports that Harry could release a second book as well, soon after the death of the Queen.

Those claims, however, were soon refuted by the couple, who called the reports “false and defamatory.”

In a press release, issued last week, Harry announced that he would be releasing his memoir late in 2022.

"I’m writing this not as the prince I was born but as the man I have become. 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, per the press release.

“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,” he added.
