Speculations have run amok that the updated version of "Finding Freedom"—Prince Harry and Meghan Markle’s unofficial biography—could spell disaster on many fronts for the royal family.

A royal expert revealed that the new chapters are likely to drop incisive details pertaining to the allegations put forth by the Duchess in her tell-all interview with Oprah Winfrey. This in turn will only deepen the rift between the Sussexes and the British Royal Family.

“That really will be the final straw,” said Duncan Larcombe to Closer magazine. “That'll be it - there will be no chance of reconciliation ever and all trust will be broken. 

"How could anyone from the Royal Family trust them again if the intimate details of conversations were leaked. Why would they want anything more to do with them? Those chapters will be extremely telling as to the state of the royal rift as it stands now, and to where it'll head in the future,” he added.

The updated version of the biography is likely to hit the stands this summer on August 5. It addresses explosive topics such as the allegations that Meghan bullied royal staff—which she denies—and the death of Prince Philip.

The book will also offer insights into Harry and Meghan’s entry into showbiz, their multi-million-pound deals with Netflix and Spotify, their new life in California, and the Queen's decision to cut them off from royal privileges and patronages including Harry's military roles.

There was a glimmer of hope that things would get better between Harry and his older brother Prince William after they were spotted being amicable with each other at Prince Philip’s funeral. It was hoped that Harry and William would start to build bridges following the Duke of Edinburgh's funeral, but the reissue of "Finding Freedom" is sure to lead to another ugly fallout between the Sussexes and the Firm, as cited in the report on Daily Mail.  

Another senior royal source added: “After Oprah, what else is there to say?” 

Duncan further added that the royal family is reeling under the shock of Winfrey’s bombshell interview with Harry and Meghan, and anything beyond would just be downright brutal. “Whatever's said will be a bombshell - everyone is just so gripped by the situation,” he told Closer, as cited by the outlet.

“But we have to hope Harry and Meghan have been encouraged by the recent progress made during Harry's trip to the UK... so that they don't do any more damage. If the content isn't vague or neutral, it could cause another huge fallout,” he added.

Earlier last week, Duncan maintained that Harry was regretful about acting on an impulse and slamming his family for allegedly mistreating his wife at the iconic host’s show.

"Finding Freedom," was declared a bestseller, with 31,000 copies sold in the UK in the first five days of its release in January. The first version hinted at Harry’s annoyances toward William for the latter’s snobbishness, and the relationship between their wives. The book also suggested how Meghan was disappointed with the fact that Kate wasn’t “welcoming enough”.
