Lady Colin Campbell, who has been a royal insider for decades, is speaking out this week to claim that Meghan Markle has political dreams that include her potentially running for president of the United States.

Campbell, 70, told Daily Mail that she believes Meghan’s move to the U.S. with her husband Prince Harry was all part of her plan to launch a political career for herself.

“I know the Duchess of Sussex has political ambitions and I’ve been told that one day she wants to run for President,” said Campbell. “I think everything she is doing, leaving the royal family and moving back to California is part of her plan and she has taken Harry along with her.”

Campbell has just written a new book called “Meghan and Harry: The Real Story,” which is due out on Thursday. In another interview with The Sunday Times, Campbell blasted Meghan by saying that she has “squandered” the “most wonderful opportunity” by leaving the royal family.

Campbell also claimed that Meghan was the “driving force” behind the decision to leave the royal family.

“If you listen to their engagement tape they both state she’s been treated very well, she’s been welcomed with open arms and they can’t wait for her to become a working member of the royal family and she said she wanted to hit the ground running,” Campbell said. “It did not work out for Meghan the way she thought it would… Meghan did not make the adjustment she should have and could have, and she is the one in my opinion [who drove the departure].”

This comes after Cambell told the Daily Star that the rift between Meghan and the royal family began just four days after her wedding to Harry, at a garden party that she attended along with the royal family.

“I knew the tremendous amount of hope the Royal Family invested in Meghan being a success,” Campbell wrote. “Hundreds of millions of people of color were rooting for Meghan, I was rooting for Meghan, being a Jamaican, I was emotionally invested in Meghan’s success.”

“Virtually everybody I know, including my Royal friends, the wider aristocracy, wanted Meghan to be a success,” she added. “But it quickly became apparent the ride may not be as smooth as everybody had hoped it would be, and it would not be quite as positive as everybody had hoped it would be.”
