Kate Middleton 'has ace up sleeve' in bid to end William and Harry feud after realisation

Princess Kate is reportedly trying to fix her husband Prince William and his brother Prince Harry's strained relationship once and for all, following her recent health ordeal.

According to a source, Kate came across theories linking cancer to stress during her chemotherapy treatment, which prompted her to extend an olive branch to Harry.

"Facing your own mortality changes people. Kate knows how precious life is and to not waste time on the past," the source shared with New Idea Magazine.

"During her chemo treatment, Kate read theories on cancer being linked to repressed anger and stress. So she's making a big effort to let go of any grudges."

The source goes onto suggest that while Harry may not be entirely accepted in Prince William's world for the time being, Kate reportedly believes it's time they acted as the "bigger people".

"The ace up her sleeve, as far as William is concerned, is that opening the door for Harry is a way of keeping him from doing something else damaging again," they added.

Once known as the fab four; Kate, William, Harry, and Meghan seemed to share a close bond when the latter first joined the family.

However, following alleged behind-the-scenes disputes, Harry and Meghan chose to step back from their senior Royal duties in 2020.

Harry, now 40, and his wife have since relocated to Montecito in California, where they live with their two children; Archie, five, and Lilibet, three.

Harry and Meghan have since provided several interviews discussing their experiences within the Royal Family, with Harry also disclosing private disputes in his memoir Spare.

Despite apparent tensions, the Royals conveyed birthday greetings to Prince Harry as he turned 40 last weekend, marking their first public acknowledgement of him in two years.

Furthermore, claims have emerged that throughout her health struggles, Harry has remained in contact with his sister-in-law.

According to Heat Magazine, a source shared: "Harry was watching Wimbledon and was thrilled to see Kate looking so radiant.

"He sent her a note to congratulate her and let her know how happy he was to see her out.

"He's just so grateful that she's on the mend and able to get back to her duties after taking time off as is Meghan."

Princess Kate recently revealed that her chemotherapy treatment is complete and that she is now focused on staying cancer free.

In a family video, she added: "Although I have finished chemotherapy, my path to healing and full recovery is long and I must continue to take each day as it comes.

"I am however looking forward to being back at work and undertaking a few more public engagements in the coming months when I can."
