Meghan Markle's estranged family will speak out in what's described as an explosive interview airing just days before King Charles III's coronation.
Her father Thomas Markle Sr, half-sister Samantha Markle, and half-brother Thomas Markle Jr will share a slew of "hidden" videos of "treasured memories, home truths and secret tapes" of the Duchess of Sussex.
In a trailer released ahead of the interview by 7News Spotlight, Meghan's 78-year-old father makes a "deathbed" plea and begs his daughter for one last chance to fix their relationship.
"How can I fix this?"
He suffered a stroke last year and shortly after this said he was "lucky to be alive".
Elsewhere in the trailer, Samantha said Meghan would "still be a waitress" if it wasn't for their father. She further claimed that Meghan and her husband Prince Harry are "unhealthy" for each other and have a "toxic relationship".
Samantha has never met Harry, and Meghan claimed during her Oprah interview two years ago that she had little to do with her half-sister growing up.
Samantha went on to try and sue Meghan for $75,000 in damages, saying she made "false and malicious statements", although the case was dismissed by a judge.
Thomas Jr also chimed in during the interview trailer, saying: "We're not going to go away."
Meghan hasn't spoken to her father in five years and he's never met his grandchildren, Archie and Lilibet.
In their Netflix docuseries Harry & Meghan, which was released late last year, the Duchess of Sussex said she was a "daddy's girl" when she was younger and was "with him a lot".
Their relationship broke down after Thomas Sr continued talking to tabloid press about Meghan, despite her pleas to him against this.
The airing of the Markles' latest interview comes just days before King Charles' coronation on May 6. Harry is attending this, while Meghan will remain in California with their two young children.
