Thomas Markle hit out at his son-in-law Prince Harry once again during an appearance on Good Morning Britain on Tuesday.
Meghan's 77-year-old father spoke to hosts Susanna Reid and Richard Madeley about the famous couple, and he was far from complimentary.
Branding the situation "silly" and "childish", Thomas declared he'll keep speaking out until his daughter contacts him.
Speaking about his son-in-law, Thomas claimed: "I think Harry has abandoned the queen and the royal family, the British people and the army, he's abandoned them all.
"All he does now is ride a bicycle around the neighbourhood that he lives in. I don't know if it's much of a life for him either, doesn't make sense."
Harry and Meghan moved to California in March 2020, and a few months later they bought a house on the former estate of Riven Rock in Montecito, California.
When Richard Madeley suggested that the couple are "certainly very rich", Susanna asked: "Do you think they're happy Thomas?"
Thomas replied: "Well, money isn't everything but the book he's writing should not be finding freedom, it should be finding money. That's all they care about now.
"Harry's coming out with a book and that can't be anything but cruel. And to insult his grandmother, the Queen, it's a ridiculous idea and it's just something for money.
"That's all they're doing, everything they're doing is for money. But to do that to your grandmother, who is 95 years old, is shameful."
Richard then asked: "Do you ever get feedback from third parties about what she thinks about you now? Do you have any information at all from the outer circle?"
"Not a word, no," Thomas replied. "There were some people quite some time ago in a magazine that said some things about me that were her friends, insults and lies.
"I've been trying to get their names and go after them for quite some time, it has happened yet," he added.
Good Morning Britain airs weekdays at 6am on ITV.
