Kate Middleton and Prince William Are 'Appalled' by Prince Harry’s Public Attacks

Prince William and Kate Middleton's relationship with Prince Harry was greatly impacted by Spare, as the Duke of Sussex painted the future king and queen negatively in his memoir.

"It may be things are going on that are not known, but it was not a surprise given Prince William's intense feelings. He was appalled by the allegations in Spare," Richard Fitzwilliams told GB News. "Given it is a deeply pressured and sensitive time for William, Catherine and their family, I don't think anyone expected Harry would see them."

"They did think he would see King Charles and he didn't, it has been disputed as to why," he added.

OK! previously reported a source claimed the Wales don't want to be around the Sussexes while Kate and King Charles undergo cancer treatment.

"Not only is there the pressure on William, but also the constant sniping from California. I'm sure he's furious with Harry, he's behaved appallingly," Tom Bower told an outlet.

"While they're establishing this so-called brand Sussex, the family here is going through torment. After Charles' diagnosis, Harry came over for half an hour, and that's it, he's done nothing else," he continued. "I can imagine that Kate and William are deeply upset by having the Sussexes' brand operation rubbed in their face while they're going through this tragedy."

In March, the mom-of-three returned to Instagram to update fans on her health after avoiding the spotlight for months.

"I wanted to take this opportunity to say thank you personally for all the wonderful messages of support and understanding whilst I've been recovering from surgery," Kate began in a video. "It has been an incredibly tough couple of months for our entire family. In January, I underwent major abdominal surgery in London. At the time, it was thought that my condition was non-cancerous. The surgery was successful, however, tests after the operation found cancer had been present. My medical team therefore advised I should undergo preventive chemotherapy, and I am now in the early stages of that treatment."

"This of course comes as a huge shock, and William and I have been doing everything we can to process and manage this for our young family. It has taken my time for me to recover from my surgery," she continued. "Most importantly, it has taken us time to explain to George, Charlotte and Louis and to reassure them I am going to be OK. As I've said to them, I am well. Having William by my side is a great source of comfort, and the love and support and kindness that has been shown from so many of you. As a family, we need some time, space and privacy while I complete my treatment. My work has always brought me a deep sense of joy. I must focus on making a full recovery. At this time, I am also thinking of those whose lives have been affected by cancer. Please do not lose faith or hope. You are not alone."

Despite the tension between them, Meghan Markle and Harry released a statement in support of Kate.

"We wish health and healing for Kate and the family, and hope they are able to do so privately and in peace," a rep for the American-based royals said.
