Prince William is apparently channeling his inner Prince Philip to resolve the conflict with Prince Harry.
The Prince of Wales follows his grandfather's example and sets out to discipline his younger brother.
A source told the Daily Beast: “There is a sense that William has taken on Prince Philip's role. Philip ruled the family with an iron fist and, as seen when he died, discipline broke down. Now William is the one calling the shots when it comes to family discipline.”
This comes as the Royal Family prepares for their summer holiday at Balmoral.
Jennie Bond, the BBC's former royal correspondent, told OK!: “It's been an incredible year for the Royal Family so far and nothing would please the King more than to have his close family gather in the peace of Balmoral for a time to take stock together, mark the passing of an incredibly difficult few months and look to the future.”
She continued: “As Catherine herself has said, cancer treatment comes with a great deal of uncertainty and that must extend to whether she will be able to spend part of the summer holidays at Balmoral. If she does go, I'm sure the whole family will want to surround her with love, support and renewed strength. She, meanwhile, will want to make the summer months as fun and carefree as possible for the children after everything they've been through.”
