A scathing new biography about Prince Harry and Duchess Meghan attempts to paint Meghan Markle as volatile, unpredictable, and manipulative.

A book written by Tom Bower claims that Meghan’reduced people to tears with her passive aggressive tone’ and demanded first-class flights and luxury accommodations for business trips before she met Prince Harry.

An ex-business associate of Meghan’s described her as “one of the most unpleasant people he had ever dealt with” by the author, who has admitted his sources were people who “don’t like” Meghan.

According to Bower, Meghan had told her closest friends and family not to talk to him, so he obtained much of his information from those who don’t like her.

The author told Good Morning Britain on Thursday: ‘She made it pretty clear to all her friends and people who work for her not to talk to me, so it was quite an uphill struggle but I got enough people to speak to me, more than enough, I got about 80 people.’
