Prince Harry, allegedly, proposed to rewrite Kensington Palace's rulebook after the success of the Sussexes' first joint tour in Australia. Allegedly, the Duke of Sussex claimed his brother, Prince William, was jealous of the victory of their first royal tour.

Prince Harry and Meghan Markle's first tour abroad as a married couple was reportedly a huge success. In just 16 days, they managed to carry out 75 royal engagements across Australia, Fiji, New Zealand and Tonga and huge crowds warmly welcomed them everywhere.

With that said, investigative journalist Tom Bower said in his upcoming book, "Revenge: Meghan, Harry and the War Between the Windsors," the controversial royal couple convinced themselves that Kate Middleton's husband was jealous of their royal tour in Oceania's success.

With the alleged jealousy, the author told The Sunday Times that the two thought it was the right time for a change. They wanted to break free from the Palace's "claustrophobic bowl" and proposed it should rewrite the rulebook.

Instead of assigning the former "Suits" star to be a supporting cast member, the proposed change would allegedly make her a campaigner-independent of Prince William, Kate Middleton and even Queen Elizabeth.

Bower added that Prince Harry perhaps encouraged the suggestion, making Meghan Markle come up with a fantasy that she could "provide the leadership the monarchy required." "Her activism would enhance the brand," he said, via Express.

He also alleged that the Duchess of Sussex gave an impression to her staff that she personified the monarchy's importance. The Sussexes were said to be asked for comments about the issue but have yet to give any.

In other news, Prince Harry allegedly vowed to "completely destroy" Prince William. Royal author and biographer Angela Levin warned about the alleged plan of Archie and Lilibet's dad. She first revealed a "potential unfiltered accounts of events," per Geo TV.

She also added that the expose would feature explosive "up-to-date stuff," like who made who cry in the Meghan Markle and Kate Middleton issue. This event was in reference of the earlier claim that the Firm received a warning about Prince Harry being filled with "a lot of poison in his blood" about what he felt about his background and family.

The claim also came days after there were warnings that Prince Harry might go "fully candid" in his upcoming memoir." The book was reportedly delayed due to some "last minute additions."
