The estrangement between Prince William, his wife Kate Middleton, and Will’s brother Prince Harry is showing no signs of healing any time soon.

42-year-old William, who is the future King of England, and Harry, 40, were reported to have been incredibly close in their younger years.

Following Harry’s 2020 decision to step away from his royal duties and the publication of his memoir Spare, there have been ongoing reports of tension between the siblings.

In his book, Harry wrote that his brother called his wife Meghan Markle, the Duchess of Sussex, ‘rude’ and ‘abrasive,’ which he termed as a ‘parroting of the press narrative’.

The confrontation led to an alleged physical altercation in which Harry writes: “[William] grabbed me by the collar, ripping my necklace, and … knocked me to the floor.”

It seems tensions are far from soothed following a report regarding Kate, William and Harry.

A source told New Idea Magazine that Kate has been left fuming following a ‘disagreement with the Prince of Wales over the Duke of Sussex’ being leaked.

Despite tensions, Kate appears keen for a reconciliation, with a source saying: “Despite all the barbs Harry’s thrown at the royal family – and hurtfully, at Kate especially – since exiting the royal family and releasing his tell-all memoir, Spare, Kate does want peace between the brothers because she knows there’s no time for long-held grudges.

“Family is everything to Kate – this breaks her heart.”

Royal reporter Katie Nicholl echoed the thoughts to the Sun.

She said: “Possibly the Princess of Wales is still open to a reconciliation in some form. I still feel it’s quite early.

“But I do think when you go through something like a cancer diagnosis and you go through the sort of journey that she has done, and you confront your own mortality, you realise life is short.”

Kate was diagnosed with cancer, which she shared with the public earlier this year in March.

She has since been thankfully declared cancer-free, saying in a statement: “The last nine months have been incredibly tough for us as a family. Life as you know it can change in an instant and we have had to find a way to navigate the stormy waters and road unknown.

“The cancer journey is complex, scary and unpredictable for everyone, especially those closest to you.

“With humility, it also brings you face to face with your own vulnerabilities in a way you have never considered before, and with that, a new perspective on everything.”

Royal expert Nicholl added that William ‘is still likely to feel very angry and betrayed [by Harry]’.
