Thomas Markle says Prince Harry wrote his memoir 'to insult his grandmother' and that Meghan Markle has disowned the family

• Thomas Markle has criticized the Duke of Sussex's upcoming memoir in a new interview.
• Thomas said Prince Harry wrote the book to be "cruel" and to insult the Queen.

The Duchess of Sussex's estranged father Thomas Markle criticized Prince Harry's upcoming memoir in a new interview with "Good Morning Britain."

In a clip from the interview shared on the official "Good Morning Britain" Twitter account, Thomas said Harry wrote the book for money despite the duke's publisher previously saying he will donate proceeds to charity.

"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," Thomas said. "That's all they're doing. Everything they're doing is for money."

The Duke of Sussex's memoir will be published by Penguin Random House in late 2022, according to a press release sent to Insider in July. The publisher did not specify how much of the proceeds would be donated or which charity they would be donated to.

Harry said in a statement at the time that the book is being written "not as the prince I was born but as the man I have become."

"I've worn many hats over the years, both literally and figuratively, and my hope is that in telling my story - the highs and lows, the mistakes, the lessons learned - I can help show that no matter where we come from, we have more in common than we think," he said.

In another clip from the interview, Thomas said that his daughter Meghan has "pretty much disowned both sides of her family" and appeared to blame Harry.

"She'd never been that way before, and once she hooked up with Harry, she changed," he said.

Representatives for the Duke and Duchess of Sussex did not immediately respond to Insider's request for comment.
