Following ongoing rumors of a feud between Prince Harry and Prince William, new reports claim the alleged rift could cause a “tragic” end to the brother’s relationship.

Since Harry married Meghan Markle, his bond with Prince William and Kate Middleton has reportedly suffered. One royal expert claims the change in the Duke of Sussex’s behavior has “soured” his relationship with his brother.

During a chat with the Daily Mail, Penny Junor reflected on how Prince Harry used to be adored by royal fans.

“As his biographer, I know there is great affection and admiration for Harry, not just in this country, but around the world. He has represented the Queen on many occasions now and been a fantastic ambassador for the British monarchy,” she explained

“He is charming, funny and modest; he has genuine compassion and a very real desire to use his position to help others; and in things like founding Sentebale, walking with wounded veterans to the South Pole, and launching the Invictus Games, he has done exactly that.

Nonetheless, Junor claimed Prince Harry’s popularity with the royal family and the public has decreased.

“Things have soured in the last year, and many of us feel this is not the behavior of the Harry we know and love — the Harry who wanted to be treated like just one of the blokes.

However, Junor suggested Prince Harry is no longer relatable, and the issue has caused tension in his relationship with Prince William 

“The Sussexes are establishing their own Foundation. William and Harry were once so close: friends, allies, brothers, always teasing; so obviously happy in each other’s company,” the royal biographer told the outlet. 

“Kate seemed to fit into the relationship seamlessly. They had each other’s backs, and there was every expectation they always would have,” she added.

However, Junor believes there is a fear that the brothers’ relationship may be damaged beyond repair. “It would be nothing short of a tragedy if that bond between ‘Diana’s boys’ was to fall apart permanently and something the public would hate to see.”

Despite speculation about Prince William and Prince Harry’s feud, the brothers appear to be in great spirits whenever they are photographed together and continue to put on a united front during public outings.
