My sister Meghan Markle's marriage to Prince Harry is toxic, says Samantha Markle in explosive new interview

PRINCE Harry’s marriage to wife Meghan has been described as “toxic” by her estranged half-sister — in her latest interview which will rile the Sussexes.

In a teaser for an upcoming TV chat — in which Meghan’s dad and brother will also speak out — older sister Samantha Markle said the couple are “unhealthy for each other”.

The Markles share new footage of their lives growing up and send an “extraordinary message” ahead of the King’s Coronation.

Dad Thomas also makes an emotional appeal to his daughter, begging to mend their relationship.

The voice-over describes it as a “deathbed plea” to “the daughter he lost”.

Thomas, who suffered a stroke last year and says he is “lucky to be alive”, says in the clip: “How can I fix this?”

And Samantha claims Meghan would be “a waitress” and not an influential figure were it not for their father.

The clip for a special on Australia’s Channel 7 Spotlight programme, which is set to air on Sunday night.

Harry and Meghan’s marriage has come under the microscope in recent weeks following claims their working relationship is “breaking apart” and they are “leading separate lives”.

Former Suits actress Meghan, who has recently changed her hairstyle in a bold new look, has added fuel to the fire by signing up with A-list Hollywood talent agency WME.

It also comes amid further claims Harry is “homesick” and is desperate to be at the King’s Coronation to support his father.

Close pal Daniel Martin, who has been Meghan’s make-up artist for 12 years, has confirmed Harry “misses the UK”.

While the Duke of Sussex will be at the Coronation in Westminster Abbey next week, Meghan will remain at their £14million mansion in Montecito, California, for their son Archie’s fourth birthday.

She is understood to also be busy with numerous lucrative work commitments and charitable projects based in the US.

They are really unhealthy for each other.

The couple were last seen together publicly on Monday night at the LA Lakers vs Memphis Grizzlies basketball game in LA.

Harry, 38, appeared to get the cold shoulder from his wife when he tried to move in for a kiss as the stadium’s “kiss cam” landed on them.

Meghan, 41, was not having any of it and turned her face away to avoid the awkward encounter.

Channel 7 show host Taylor Auerbach announced the news of the latest interview on his Twitter profile, writing: “WORLD EXCLUSIVE: This Sunday on @7NewsSpotlight — Meghan Markle as you’ve never seen her before.

“For the first time, the Markles unite with an extraordinary message on the eve of King Charles III’s coronation.

“These hidden tapes will stun the world! Only on @Channel7.”

In March this year, Meghan had a lawsuit filed by half-sister Samantha dismissed after a judge ruled in her favour.

The Duchess had been accused of spreading “malicious lies” about Samantha during her 2021 Oprah Winfrey interview, and again in 2020 with statements to reporters.

I’m lucky to be alive. How can I fix this?

In Montecito, the Sussexes keep to themselves in the exclusive celebrity enclave, rarely venturing into town.

They have seemingly done little to integrate themselves into the local community.

Neighbour Frank McGinity, 88, says he felt rudely snubbed by the couple when he called at their home on the former Riven Rock Estate to share a film he had made on the history of the area.

He said: “I have a big house next to Harry and Meghan’s property and I live in the guest house while renting the main house out on Airbnb.

“Harry and Meghan live on old McCormick property and I went up to their gate with the films on a CD, but they weren’t interested.

“The gate guy turned me away and wouldn’t take the film, just saying ‘they’re not interested’.

“I was trying to be neighbourly. If they were interested in the neighbourhood I’ve got a lot of information.”

Mr McGinity, who runs a successful accountancy firm with offices in Santa Barbara, added: “We don’t see them very much around here.”

On the royal couple settling in Montecito, Mr McGinity added: “It’s surprising they came here.

“People are typically older.

“It’s where the elephants come to die.”

The couple have been seen dining at Lucky’s steakhouse on the main Montecito high street — where a 12oz filet mignon will set you back $99.

But most residents say they are rarely seen in the area.
