Prince William has privately written off his relationship with Prince Harry as beyond repair, with royal experts telling Fox News that the future king now views his younger brother as 'totally untrustworthy' and has adopted strategic silence as his response.

Far from hoping for reconciliation, William is said to be drawing a firm line between the brothers' futures, consolidating his identity as the next king while shutting the door on the drama that has defined the rift for years.

While speaking withFox News, royal expert Helena Chard said that Prince William is done with the drama surrounding his relationship with Prince Harry. The future king's silence about the ongoing feud is a deliberate strategy, not an avoidance of the issue.

'This feels like a permanent royal reset. But William's silence isn't a mystery. It's a strategy. Loyalty cuts both ways, and as they say, "Betrayal has a long shelf life." Prince William is known to take a harder line than some. He's setting his agenda for the future of the monarchy. There's a difference between being ruthless and holding people accountable. He's fearless and has a strong moral character,' she said.

During the same interview, royal expert Richard Fitzwilliams said that Prince William's ruthless side is coming out amid the feud because he no longer trusts his brother.

'William regards his brother as totally untrustworthy. [He] early on laid down the markers for his apprenticeship before becoming king, priority and privacy for his family,' he said.

During a previous interview, royal expert Roya Nikkah claimed that the Prince of Wales tends to hold grudges against those who have wronged him and is known to take sides.

'If someone picks the other side, he remembers that,' she said.

Prince William and Prince Harry were close growing up, though their diverging roles created tensions from an early age.The Duke of Sussex alluded to the dynamic in the title of his memoir, a source of ongoing bitterness between the brothers.
