Meghan Markle’s estranged father has pleaded for forgiveness and permission to see his granddaughter Lilibet in the trailer for a tense interview.

The 76-year-old, who hasn’t talked to his daughter in three years, threatened to disclose her “dirty laundry” while he isn’t allowed to visit the baby.

He stated he hadn’t spoken to Meghan or Harry in three years in a preview for an interview with 60 Minutes Australia, which will premiere this Sunday.

Prince Harry and Meghan Markle had their second child Lilibet Diana on June 4th, and Thomas Markle was spotted telling reporter Tom Steinfort that he just found out about Meghan giving birth to his grandchild over the radio.

“I’ll be very disappointed that I don’t get to hold my granddaughter,” he said.

Despite his apologies, the 76-year-old risks further deteriorating his relationship with the Duke and Duchess of Sussex by threatening to reveal “dirty laundry.”

He said: “You want dirty laundry? This is the first time I’ve ever discussed these things.”

He continued: ‘The bottom line is she didn’t lose me, she made a statement saying she lost me, she didn’t lose me, I would’ve always been there for her, I’m there for her now if she wants me.

Thomas appeared in photos ostensibly preparing for the royal wedding, including a tuxedo fitting and reading a book about the United Kingdom in an internet café.

He opted not to attend the wedding in the days preceding up to it in May 2018 to avoid humiliating his daughter and her new royal relations. Later, it was revealed that he was in the hospital for emergency heart surgery.

In the 40-second teaser clip, which is being marketed as yet another shocking tell-all interview, the reporter asks Thomas if he believes Meghan still loves him.

The Duchess of Sussex cut out her father after she discovered that he had arranged set-up shots of her with a paparazzi photographer.

He appealed with his daughter to restore communication with him, calling it “one dumb mistake.”

In response to her father’s treatment of her, Meghan told Oprah that she “genuinely can’t imagine doing anything to intentionally cause pain” to her son Archie in the tell-all interview.

Meghan’s comment during the interview, in which she stated she considered suicide when pregnant with her son Archie, was also addressed by the estranged father. “I’ve been pushed around and knocked down for one thing I did. For one big mistake I made and I have apologised for it as many times as I possibly can. However, I love my daughter very much. Had I known that she’d been having psychological problems, I would have been there for her,” Markle said on ‘GMB’.

Lilibet “Lili” Diana Mountbatten-Windsor, the Duke and Duchess of Sussex’s second child, was born on Friday, June 4th, at Santa Barbara Cottage Hospital in Santa Barbara, California.

The name choice pays honor to the queen at a difficult time for the Windsors, who are mourning the passing of the Duke of Edinburgh. Lilibet is the Queen’s family nickname.

Markle has also never met Prince Harry or Archie, Harry’s other grandson.
