According to Lady Colin Campbell, Prince Harry is a dimwit in comparison to his wife Meghan Markle. The surprising revelation was made by the author, who is promoting her latest book “Meghan and Harry: The Real Story,” while chatting to new!  magazine (via the Daily Mail).

Lady C said that “royal insiders told her that Meghan is playing him like a violin.”

The former I’m A Celebrity participant and royal biographer, made the shocking accusations on her YouTube channel.

“In my opinion, Harry is a much less intelligent character than Meghan is,” she said. “And I think he’s so desperate to please her and go along with whatever she says, no matter how ill-conceived it is. He is that besotted with her.”

Campbell, 70, also stated that the pair has a “very strong relationship,” but that Meghan is the dominant partner.

She went on to say that Markle is the one who wears the pants in the relationship, and she likened her to Princess Diana.

“She wears the trousers and is as dominating, charming and captivating a personality as Princess Diana was in her marriage,” she told the publication.

“They were of the opinion that Meghan – as I have repeatedly said – was playing Harry the way Jascha Heifetz used to play the violin,” she explained.

Lady C then went on to say that Jascha Heifetz was one of the greatest violinists of all time.

She went on to remark, “It’s high praise indeed for me to say that Meghan is an artist of the highest order where playing Harry is concerned.”

“There is little doubt in my mind, having heard all the things privately that I was privy to, [Harry’s] loved ones were deeply concerned what was going on in that relationship.”

As a child, the red-headed prince, 35, struggled academically. He stayed at Ludgrove for an extra year to boost his marks before applying to Eton.

He graduated from Eton College with two A- Levels, a B in art and a D in geography. One of his former professors said that he was a “weak student” and that personnel at the elite institution plotted to assist him in cheating on examinations.

A tribunal determined that “the prince had received help in preparing his A-level ‘expressive’ project, which he needed to pass in order to attend Sandhurst but didn’t rule that it was cheating.”

Both Eton and the royal family categorically denied the allegations.

According to Page Six, Harry suffered academically, but Markle has a double degree in theatre and international relations from Northwestern University.

Lady Colin believes Markle’s transfer to the United States and the couple’s departure from royal responsibilities say volumes about her future intentions.

“I know the Duchess of Sussex has political ambitions, and I’ve been told that one day she wants to run for president.”

During an hour-long Q&A session with fans, Lady C also referred to Meghan as “extremely manipulative.”

“Harry doesn’t seem to be falling too far behind her at the moment,” she said.

This was in reaction to concerns on the Prince’s remark about his mother’s death during the Apple+ documentary series, The Me You Can’t See.
