King Charles could be headed for another royal headache if Prince Harry and Meghan Markle strike a deal with the BBC, according to insiders who claim the monarch would be furious if the couple used the network to once again air private royal drama.

The Duke and Duchess of Sussex are reportedly exploring new television opportunities in Britain after returning from California with their children, Prince Archie, 7, and Princess Lilibet, 5.

While Harry and Meghan are expected to keep their $29 million mansion in Montecito, California, the couple could spend considerably more time in the United Kingdom — potentially opening the door to lucrative deals with British broadcasters.

One royal source claimed the possibility of the Sussexes working with the BBC would immediately raise alarm bells inside the Palace.

“The prospect of Harry and Meghan working with the BBC would inevitably cause anxiety at the Palace,” the source told RadarOnline.com.

The insider said Charles has been attempting to quietly repair his strained relationship with Harry and reportedly wants to avoid another media firestorm involving the Royal Family.

“If it became another vehicle for discussing private royal matters, he would be furious,” the source claimed.

Harry and Meghan are said to be considering documentaries and factual entertainment programs, with their increased presence in Britain making it easier to work directly with U.K. production companies.

A senior television industry source said the couple would not necessarily need another massive Netflix-style contract.

“Being back in Britain completely changes the landscape for Harry and Meghan,” the source said. “They can potentially make individual programs with the BBC or commercial broadcasters and retain much greater freedom over what they produce.”

The potential move comes after the Sussexes’ once-booming media empire suffered a series of setbacks.

Harry and Meghan signed a reported $100 million deal with Netflix after leaving royal duties in 2020.

That partnership produced the explosive Harry & Meghan docuseries, along with Heart of Invictus and Polo.

But several other projects never made it to viewers, including Meghan’s animated children’s series Pearl and a planned adaptation of Carley Fortune’s novel Meet Me at the Lake.

Their reported $20 million Spotify deal also came to an end in 2023 after Meghan’s Archetypes podcast ran for just 12 episodes.

Spotify executive Bill Simmons later publicly blasted the couple, calling them “grifters.”

Meghan went on to launch Confessions of a Female Founder through Lemonada Media and expand her As Ever lifestyle brand.

Her Netflix lifestyle series With Love, Meghan lasted two seasons.

Still, Harry and Meghan’s biggest media successes have overwhelmingly centered on their own lives and their turbulent relationship with the monarchy.

Their 2021 interview with Oprah Winfrey became an international television event, while Netflix’s Harry & Meghan drew massive attention. Harry’s tell-all memoir Spare also became a worldwide bestseller.

That history could make any relationship with the BBC especially uncomfortable for Charles.

Unlike Netflix or another streaming platform, the BBC is Britain’s national broadcaster and has had a decades-long relationship with the monarchy.

A Palace insider claimed that distinction would make a Sussex deal particularly sensitive.

“The BBC carries a significance that another streaming service simply doesn’t,” the source said.

The insider added that seeing Harry and Meghan earning money from the broadcaster could already prove uncomfortable, but any discussion of private royal affairs would take tensions to another level.

Not every Sussex project has generated the same kind of attention.

Their Polo series failed to crack Netflix’s global top 10, fueling questions over whether audiences remain interested in Harry and Meghan when the Royal Family is not part of the story.

British producers could instead focus future programs on Harry’s charitable work, including the Invictus Games.

“Harry remains enormously recognizable and Meghan understands television,” one industry insider said. “The challenge is proving they can deliver compelling programs without returning repeatedly to the Royal Family.”

Despite Harry’s reportedly improving relationship with his father, the Sussexes are not expected to return as working members of the monarchy.

But if their return to Britain leads to a major BBC television deal, the uneasy royal truce could be tested all over again.
