Following the death of Queen Elizabeth II, King Charles III is said to have demanded something massive from Prince Harry and Meghan Markle.

Since the Duchess of Sussex is scheduled to give the first interview following the Queen's death on her Spotify podcast, "Archetypes," it's the monarch's worst nightmare.

While the third installment of the controversial podcast was supposed to be released on Tuesday, it has been postponed, and the subsequent broadcast is set to air on Sept. 20, the day after Queen Elizabeth II's state burial at Westminster Abbey.

The day marks the beginning of a fresh conflict between the King and the Duke and Duchess of Sussex, after King Charles III barred the former "Suits" star from attending Queen Elizabeth II's deathbed at Balmoral Castle.

An insider told Radar Online that Prince Harry's father was "surprised" by Meghan's podcast and that another episode might be the "first interview" that any member of the British royal family conducts since the Queen's death.

The insider noted that, although being a significant issue, it is the last thing King Charles III needs to think about right now.

"The King does not want the Duchess of Sussex discussing anything about the family's interactions or events surrounding this very solemn occasion."

In terms of the monarch's request, the source claimed he will be urging advisers to encourage Prince Harry to persuade his wife to "stop the podcast once and for all," as he is "extremely anxious" that his daughter-in-law may not realize the severity of the issue.

In reality, according to the source, King Charles III is aware of what the Duchess of Sussex stated in a recent interview: she was never made to sign anything that would prevent her from divulging British monarchy secrets.

"He knows Meghan is staunch in her opinion that she, not the family, has control over what she says publicly."

Furthermore, the queen hopes that "common sense, civility, and moderation" will guarantee that the California-born B-list celebrity makes the correct decision not to discuss the Windsor family or Queen Elizabeth II's death.

Aside from the risk that facts of Her Majesty's death are anticipated to be exploited, her oldest son may also be depicted in an unfavorable light.

After all, it was King Charles III who reportedly advised Prince Harry that it wouldn't be proper if Meghan visited the ill Queen on her deathbed.

Queen Elizabeth II died on September 8, UK time, in Balmoral Castle.
