In the wake of Prince Harry's memoir, Spare, a royal expert has urged Prince William to break the royal family's unwritten rule of "never complain, never explain" and address the allegations made by his younger brother.

British author Alexander Larman believes Prince William should have shown concern for Prince Harry by offering an interview to discuss his sibling's claims and acknowledge his struggles.

Larman, who penned The Windsors at War: The King, His Brother and a Family Divided, told Us Weekly that the royal family would have benefited from demonstrating their concern for Prince Harry amidst the accusations leveled against the monarchy.

A Call for Prince William to Respond to Prince Harry's Allegations Larman said, "I'm on record saying that they should have responded," and added, "I think Prince William should have given an interview in which he extended the hand of brotherhood." He suggested that the Prince of Wales could have expressed the royal family's concern for his brother.

"We understand that he [had] the most awful traumatic shock when his mother died so young," Larman continued. "You know, we know life has been hard for him."

Larman also acknowledged the difficulty of Harry rebuilding his relationship with the royal family after the publication of Spare. Prince Harry's revelations in the memoir reportedly strained his relationship with Prince William even further.

Prince Harry Aware of the Impact Spare Would Have on His Relationship with Prince William According to Express, Larman said Prince Harry was well aware that the details in Spare would significantly impact his relationship with Prince William. Despite this, the Duke of Sussex chose to publish the book, knowing that reconciliation with his older brother would be challenging.

Larman noted that speculation about the two brothers' relationship continues to swirl, with questions about whether they will reconnect or even speak to each other. "I think it's fair to say no," he said, "because after Harry published Spare, he knew exactly what he was doing... to publish a book like Spare, with that level of attack on your family, is essentially ending any kind of relationship you're ever going to have."
