PR expert Mark Borkwoski told the Guardian that, while Harry wants to “be of value” and make different content, he may struggle.

He said: “Netflix hasn’t really worked, Spotify hasn’t really worked, and that is because the sort of content that they feel they want to produce, the platforms don’t believe it has any value.

“Harry clearly wants to be of value. They have to produce something that is meaningful, that captures their values. But, unfortunately, people don’t want that. People want the ‘sidebar of shame’ sort of stuff, and turning up moaning and shouting and being disruptive.”

On Meghan, he added: “Look, if you’re appearing on red carpets and premieres, that means you’re putting yourself on show for the type of people who might cast you, book you, use you. That’s what Meghan’s been about.

“The trouble is, all this high-ended stuff around the values that they portray, it hasn’t delivered for them. And they need to make money.”

Joe Little, managing editor of Majesty magazine, believes Harry and Meghan will stop sharing details about their lives in the Royal Family.

He said: “You’d hope not. But I would say they’ve done a huge amount of damage to the institution as a whole, intentionally or unintentionally, in the past few years.

“I don’t think Spare has presented Harry in the best light. I think perhaps scores had to be settled, but at what cost? But you just have to draw a line and move on. Perhaps he feels that he’s said all that needs to be said.”
