The pair’s relationship continues to be fractured following Harry’s decision to step away from being a working royal.

A former royal aide has highlighted Prince William’s red line in regards to his relationship with his brother Prince Harry. Ailsa Anderson, Queen Elizabeth II’s former press secretary, told People magazine that William sees Harry’s current set-up in America as fundamentally unacceptable.

Harry stepped away from royal duties in 2020 for a life in America, with the royal insider believing that there is frustration over Harry’s pursuit of independence whilst clinging onto the perks of being a royal. According to Anderson, the arrangement remains “a nonnegotiable” for William, the heir to the throne.

She added: “He wouldn’t countenance any acceptance of it.” During a surprise visit to Ukraine last month, Prince Harry was asked about claims that he is now a “non-working royal” after leaving Britain to become financially independent Stateside.

The Duke of Sussex dismissed the idea, saying: “I will always be part of the royal family,” he said. “I am here working, doing the things I was born to do.”
