An explosive new royal book has claimed that the Princess of Wales knew Prince Harry and Meghan Markle “weren’t to be trusted” and that any engagement with the pair should be treated with “the utmost of caution”.

Writing in an extract from his upcoming book William & Catherine: The Intimate Inside Story, the Daily Mirror’s Royal Editor, Russell Myers, explains that Prince William and Princess Catherine had been left “wounded” by Harry and Meghan’s assertions made in their interview with Oprah Winfrey, specifically their claims of being “trapped” in the Royal Family and the disclosure of a private text exchange.Myers writes: “In the aftermath of Harry and Meghan’s Oprah interview, the Sussexes’ version of how the family and the institution had conspired against them, had created a siege mentality in the palace. Harry’s presence at the funeral just ensured these feelings stayed fresh in everyone’s minds.”

He continues: “William and Catherine were both wounded by the numerous accusations and the presentation of Harry and Meghan’s ‘truth’.

“William was most aggrieved by Harry’s assertion that he was “trapped” in the system, while Catherine felt deeply let down over Meghan’s disclosure of a private exchange, which sparked claim and counterclaim regarding the fitting of dresses before the Sussexes’ 2018 wedding.

“It compounded, in Catherine’s mind, a key difference between her and Meghan, who she no longer believed she could trust.

“A source said: ‘She (Catherine) was very clear that any engagement with Harry or Meghan should be with the utmost of caution because it was obvious that they weren’t to be trusted.’

One of the major difficulties in the relationship between the Princess of Wales and Meghan was allegedly over an exchange involving Princess Charlotte’s flower girl dress ahead of Harry and Meghan’s wedding.

Meghan referred to the incident in her sit-down with Oprah Winfrey. She explained: “A few days before the wedding she was upset about something, pertaining to, yes, the issue was correct, about flower girl dresses, and it made me cry, and it really hurt my feelings.

Other sides of the story have emerged, with it also claimed that Meghan made Catherine cry, rather than the other way around. In Tom Bower’s 2022 book, Revenge, he wrote that “Meghan compared Ivy [Mulroney] favourably against [Princess] Charlotte” when discussing her young bridesmaids, causing Catherine to cry.
