As Oscar Wilde could well have said about the supposedly privacy-obsessed Prince Harry: “There is only one thing in the world worse than being talked about, and that is not being talked about.” You can guarantee whenever Harry opens his mouth it will merely worsen and widen the rift he has with his older brother Prince William – not heal it. Because shouting from the rooftops that you have a “broken relationship” with a family member – and implying that you are somehow the victim in this row because only you are speaking about it – will be yet another slap across smarting William’s already bruised face. If you look up ‘Victim Mentality’ in a textbook, Harry’s picture will be right there beside the description.

Only Harry can write a bestseller book Spare about being supposedly hard done by (due to the biological fact he was born after his brother), viciously attack his own family, stepmother and sister-in-law and humiliate them, and then moan: “Why won’t anyone talk to me anymore?!”

Speaking to GQ this week, Harry has broken his silence – yet again – on his “broken relationship” with his understandably fed-up brother, a future king with far more pressing concerns on his mind than massaging his self-absorbed little brother’s insecurities. While the victims of his secret-spilling in Spare – King Charles, Queen Camilla and the Prince and Princess of Wales – welcomed the Sultan of Oman to a rainy day Windsor for his state visit to the UK on Tuesday – GQ were promoting their new Harry interview.

In it, they asked the Duke of Sussex if he grieves for the relationship he once enjoyed with the Royal Family. Harry told them: “Yes, of course. I think from a family perspective, again, another massively relatable issue for so many people, sibling disagreements, broken relationships between kids and their parents, kids and one parent.

“That continues to come up with me the whole time with people that I speak to, so I know how relatable it is. People may look at us and go, ‘How are you gonna work it out? Maybe that will help me work my stuff out’.

“Some people don’t want it to work out. I want it to work out. With everything else that’s going on in the world, the most important thing is to reconcile—that’s the key point. […] Scars stick around forever.”

The quote that will simply infuriate William the most must be “some people don’t want to work it out,” implying all this is his brother’s fault.

Even if William has the inclination to work things out with his brother, he knows it will be played out in public like an episode of Dynasty because Harry has proved with Spare that he cannot be trusted to keep schtum about family matters – the minute you tell him anything, it’s on TV or a new chapter in a book.

A sieve holds more water. If Harry genuinely wanted to patch things up he needs to try to keep quiet for a while and stop playing the eternal victim card.
