Though Buckingham Palace is yet to comment on Prince Harry and Meghan Markle's upcoming Netflix docuseries, "Harry & Meghan," a royal commentator believes King Charles III faces a "stark choice." The new reigning monarch will find it hard to avoid this drama, so how will he react to it?

Royal expert Richard Fitzwilliams revealed "Harry & Meghan" trailer just hinted at the attacks Prince Harry and Meghan Markle would do against the royal family and the courtiers. So, what measures would King Charles take to defend the Firm?

The commentator told Express that the problem after the Sussexes held an all-out interview with Oprah Winfrey last year was "how to respond." About 50 million people watched the talk, leaving enormous damage to the monarchy, especially with the allegations about racism and mental health.

"The choice is stark. Doing nothing, a 'business as usual' approach is highly unsatisfactory," Fitzwilliams stressed. He was sure that the event would surely turn into a media circus if the palace chose to rebut the allegations or take legal action.

If they chose to remove Prince Harry's title, it would take an Act of Parliament to take off his dukedom, but he would remain a prince. Hence, he believed King Charles had to make a drastic choice to "shun" his youngest son until a truce between the couple and the Firm happened.

Fitzwilliams suggested that the most likely move to make is not to invite Prince Harry and Meghan Markle to his coronation. He continued that all contact with them should be banned until there's a sign of reconciliation from them.

He stressed that King Charles is still Prince Harry's father, so his eldest brother, Prince William, might protect his legacy. However, though they're already under a big threat, they have yet to respond.

A different source told Us Weekly that the Sussexes' docuseries had left a "bad taste" in the monarch's mouth. Allegedly, he's more worried about it than anyone in the monarchy.

The insider added that His Majesty didn't want to deal with the drama after just taking over the throne from his late mother, Queen Elizabeth II-three months after her demise. Though he's putting on a brave face, he's concerned that "Harry & Meghan" would cause "irreparable damage" to the monarchy.

Netflix dropped the official trailer for the Duke and Duchess of Sussex's controversial six-episode series. The two talked about their decision to resign from their senior royal roles in the clip.

The controversial pair also seemed to hint that the royal family was behind all the negative news about them before they officially exited the U.K. For starters, Prince Harry and Meghan Markle left their senior duties behind in January 2020, making it permanent in February 2021.
