The saddest part in the book Finding Freedom is the reality of Prince Harry’s split with his brother.
Prince William is the only other person who understands the intense scrutiny of being a modern prince.
It is a weighty responsibility that goes with their position of immense privilege.
As their cousin, Prince Michael of Kent, once told me: “If you have privilege, you have no option but to accept some kind of obligation and responsibility. You can’t have all the perks without pulling your weight.”
But while it seems William has accepted the restraints of his senior position, Harry appears to think he has done his share of weight-pulling.
Diana left the bulk of her £17million divorce settlement to her sons.
As heir in line, William will inevitably collect the greater share. He will one day be the outright owner of Balmoral and Sandringham and he – not Harry – will be the custodian of Buckingham Palace and Windsor Castle.
The discrepancy in prospects has always caused difficulties between them and there have been occasions when Harry appeared jealous.
“I’m not the important one,” Harry often said. So when William cautioned his brother not to rush into a marriage with Meghan, it was a recipe for trouble.
As the wedding approached, Kate did her best to smooth things over.
But sadly, it didn’t resound with Meghan who, according to the book, felt Kate could have made much more of an effort.
Meghan’s friends complained that throughout her “royal life” she felt there was little support. Often, they would be told their projects had to wait when the Prince of Wales or Prince William had an initiative or tour being announced at the same time.
That is, of course, how the monarchy works and has always worked.
But Harry and Meghan seemed determined to turn it into a popularity contest, which it certainly is not.
Looking at the book, it is clearly something William has accepted but Harry and Meghan have failed to understand.
Now, they never will.
And sadly, the frosty atmosphere at Harry and Meghan’s final engagement as working royals – at the Commonwealth service at Westminster Abbey in March – revealed just how much relations between the once-close brothers and their wives have soured.
