Prince Harry and Meghan Markle pose a great threat to the royal family, a royal author said.

The royal family is yet to get rid of talks about Prince Harry and Meghan's feud with the other members. With that, biographer Tom Bower called the Duke and Duchess of Sussex as "considerable threat" to royals, leading him to ask the monarchy to "astute management" to minimize the threat.

Speaking with "60 Minutes," Bower noted the negative impact the couple might bring despite stepping down as senior royals two years ago.

"I think they pose a considerable threat. [But] the question is how the Royal Family minimizes the threat and dilutes the danger and that requires astute management," he said, per Express.

Bower left the comment following the controversial statements they revealed against the royal family.

It became his latest tirade days after he claimed that Meghan tried ghosting him.

In an interview with ITV's "Lorraine," Bower claimed that he tried to include the "good side of her" in his book. However, he found it difficult to get in touch with sources close to her.

He added that he was being cut off by the Duchess of Sussex, accusing her of ghosting people.

Prince Harry, Meghan Markle Have Bad Image?

Bower's new comment came out after releasing "Revenge: Meghan, Harry And The War Between The Windsors."

In the book, he disclosed that Prince Harry's friends did not want him to marry Meghan. However, they called him "f- -king nuts" for continuing to do so even after she criticized them for their "jokes about sexism, feminism and transgender people."

"Without hesitation, Meghan challenged every guest whose conversation contravened her values. According to Harry's friends, again and again she reprimanded them about the slightest inappropriate nuance. Nobody was ­exempt," the book claims, per New York Post.

But royal author Duncan Larcombe claimed that Prince Harry was already regretting the decision he knew he should have never made.

In an interview with Closer Magazine (via Express UK), Larcombe noted that the royal prince looked homesick.

"Harry's suddenly playing polo again and drinking with his new friends - all things he used to enjoy doing in the UK. Meghan is cheering him on on the sidelines, helping create this perfect LA life for him to justify what he's given up in the UK," he went on.
