Thomas Markle has dealt a fresh blow to Prince Harry over his treatment toward his dad, Prince Charles.
Meghan's estranged father is maintaining his disapproving stance on his daughter and husband Harry after the pair made the decision to step down as senior members of the royal family last year.
But things have become even more intense as Thomas didn't hold back in slamming his son-in-law Harry during an explosive chat with 60 Minutes Australia.
In the interview - which took place three months after Harry and Meghan's own bombshell chat with Oprah Winfrey - Thomas called Harry "cold" for his actions towards his own father, Prince Charles.
Thomas' comments come after Harry accused his father Charles of "making him and William suffer".
His comments came after Harry criticized his dad in the third episode of his new Oprah documentary about mental health.
Entitled 'Finding What Works', the episode saw the Duke of Sussex open up about his relationship with Charles, saying: "My father used to say to me when I was younger and he used to say to both William and I 'Well, it was like that for me so it's going to be like that for you.' That doesn't make sense."
Thomas went on to slam Harry and Meghan's decision to repeatedly "abandon" the royal family, further criticizing the Duke of Sussex for the way he treated Charles.
Per Daily Mail, Thomas told 60 Minutes Australia: "I don’t like to say it but I’ve got to say it. I don’t know of anybody that is that cold to do this."
He then opened up about his own estranged relationship with daughter Meghan, calling her cold too, before adding: "And now like I said Meghan did it to me and now Harry’s doing it to his father.
"That’s a cold thing to do and even more cold to do it to the Queen who’s in her nineties. None of this makes sense."
Thomas added that he was largely confused over Harry's decision to turn his back on the royal family with Meghan.
"I’m not bitter, I’m confused I just don’t have the answer. I want the answer," he said. "If I had done something terribly wrong that would be fine but I haven’t. So I just want an answer."
When asked about whether he is to be blamed for the couple's estranged relationships with their families, Thomas said: “If I am [to blame] tell me why and how and I’ll try to fix it but I don’t know why or how."
