As William’s future as sovereign looms, the ongoing feud with his brother Harry poses a significant challenge for Middleton as his future queen. The rift between the brothers began long before Harry and Meghan Markle’s departure from the royal family in 2020, as they cited attacks by the U.K. press fueled by palace courtiers and tacit support from the royal family.

A source close to the royal family revealed, “Kate is deeply troubled by William’s ongoing rift with his brother.” William has reportedly threatened to strip Harry and Meghan of their Royal Highness titles once he ascends to the throne, a decision that Middleton may not necessarily agree with.

Furthermore, Middleton is displeased with the Sussexes’ public criticism of her and William, especially in interviews, a Netflix series, and Harry’s upcoming memoir, Spare. Despite these challenges, Middleton, like Harry, believes that reconciliation within the royal family is essential for the stability of The Firm.

The source added, “Persuading William to let go of grudges has been daunting, but she’s aware she’s the only one in the royal family who can possibly do it.” Middleton’s role as a peacemaker within the royal family may become increasingly crucial as the dynamics within the monarchy continue to evolve.
