Prince Harry reportedly ‘ruined his bond with Kate Middleton’ after making snide remarks that violated a major rule.

Prince Harry’s once close bond with the Princess of Wales was runied after he broke a major royal rule, an expert has claimed.

Kate was once seen as the peacemaker who many thought would be able to help Harry and his estranged older brother Prince William bury the hatchet. But in his memoir Spare, which was released almost two years ago, Harry dished on his sister-in-law. In the book and in several interviews to promote it, he accuses Kate of “stereotyping” his wife Meghan Markle, saying her behaviour created a barrier and shared details of a row over bridesmaids’ dresses at the time of his wedding, which left Meghan in tears.

He also writes how Kate asked for an apology from Meghan when she accused her of having “baby brain” following the birth of Prince Louis and that Kate “grimaced” when Meghan borrowed her lipgloss.

And acccording to royal expert and author Katie Nicholl, this led to a complete breakdown of Kate and Harry’s relationship as the princess is “very disappointed”. She previously told The Sun : “When you think of the personal revelations, and I think you can call them snide remarks made about Kate in Spare, Harry broke the one rule and that is staying silent on family matters.

“While Kate and Harry used to be very, very close, there’s been a complete breakdown of that relationship. I don’t think Kate does angry. I think it is more a case of feeling very disappointed, very let down and feeling hurt knowing that she had no right of reply – and Harry knew full well she had no right of reply.
