Since Thomas Markle’s heart attack, which prevented him from attending his daughter’s wedding to Prince Harry, Meghan’s sibling has alleged that the Duchess has “ignored her father.” Meghan’s half-sister also claimed that the Duchess had exploited her mental health to handle others “like dishrags.”

In an interview with Australian morning show Sunrise, the American said: “I think the burden is on her.

“She is the one that isolated the entire family both sides of the family the Raglands and the Markles.

“She has ignored my father since his heart attack.

“It is only humane to make that right and no one can do that but her.”

“I’m hoping that she will resolve things with our father, because it’s only called for. That needs to be repaired.”

Thomas, 71, today that he still hasn’t seen baby Archie after Meghan’s second pregnancy was revealed.

He had stated that he would be able to testify against his daughter when she filed a High Court privacy lawsuit, which she won, after a British newspaper reprinted excerpts from a letter she gave him.

Meghan is the first born of her father’s second marriage to Doria Ragland, and she is her father’s only child.

According to sources, Markle Sr. “doted” on Meghan, which might have irritated her older siblings.

Samantha Markle appeared on the Australian show to advertise her latest memoir, The Diary Of Princess Pushy’s Sister Part 1, which she insisted was “more of a sociological journey” than a tell-all about her popular sister.

“There is nothing shocking or disparaging in the book,” she said.

Meghan retaliated after the piece was released, claiming she hadn’t seen her sibling in nearly two decades and dismissing suggestions she knew anything about her.

She said to Oprah: “I think it would be very tell all when you don’t know me. I grew up as an only child I was an only child growing up.

“The last time I saw her, 18 or 19 years ago and before that, 10 years before that.”

Samantha hit back.

She said, “I don’t know how she can say I don’t know her and she was an only child. We’ve got photographs over a lifespan so how can she not know me?”
