Many concerned subjects have been worried about Prince Harry’s mental state since the airing of his shotgun-to-the-foot BBC interview. And in truth he does seem to be displaying all the hallmarks of what I believe psychiatrists call being a “whining self-obsessed pillock”. Whether of not he's suffering mentally one thing is clear – he’s driving the rest of us nuts. And he’s not a quick learner is he our Harry? Not the sharpest knife in the drawer. No royal TV interaction since Logie-Baird said ‘I wonder what this cathode ray tube does?’ has gone well.

Even the very first BBC fly-on-the-wall documentary “Royal Family”, as far back as 1969, deferentrial as it was, demeaned the institution. The journalist Peregrine Worsthorne said at the time it was dangerous to shatter the royal mystique - that familiarity would breed contempt. And 50-odd years later that prediction has reached its apotheosis in Harry and Meghan, wheeling themselves out to worldwide broadcasters at every opportunity to demand people stop looking at them.

And achieving nothing, absolutely nothing, but the contempt of a disbelieving nation which was once rather fond of the couple.

If you’re old enough, remember the horror that was Royal It’s a Knockout (if you’re not, just Google), or the mawkish hokum that was Princess Diana’s interview with the discredited hack Martin Bashir, and finally Prince Andrew’s catastrophic Newsnight head-to-head with Emily Maitliss which was rightly described as “nuclear explosion level bad”.

Interestingly, there are parallels between Harry and his Uncle Andrew - so maybe there is something about being the second in line, the spare, the not-wanted-on-voyage?

One paper described the Prince Andrew interview as: “An exchange that summed up a grotesque mismatch between the Duke of York's language and demeanour, and the gravity of the allegations which continue to surround him.” It further accused him of the “obtuse self-absorption of a prince.”

Sounds a bit familiar that doesn’t it?

Because Harry’s self-absorption is also total. By birth he was dealt the absolute winning hand in the game of life but just cannot seem to grasp how spectacularly lucky he is.

So instead of an immensely grateful, happy, Harry we have a whining, mind-bogglingly entitled, failed royal who – even at the age of 40 – encapsulates the puerile, self-absorbed, me-me-me generation.

At one point in Friday’s BBC interview Harry whinges: “At this point I’m feeling very let down.”

Ya think Harry?

What about the nation which provided you with your charmed life of untold wealth and glamour, your fabulous education, your homes, and yes, until you ran away from your responsibilities, your security.

Do you not think we feel a bit cheated too?

When Harry is back in an official capacity by the way he gets a full security detail. But if he pops over to see his mates then I’m afraid he picks up the tab for security – not you and me… which seems entirely right and fair surely.

Of course no Harry and Meghan interview would be complete without the obligatory side-swipe at the royal family – unfounded allegations as usual of course.

At one point he actually insinuates his dad the King might not have long left – an absolutely appalling thing to say. Then he blurts out that “some people” – people he knows but is of course not naming – apparently want him killed in a car crash.

Surely that is the full horror of what he was insinuating right?

Read the lines: “At the heart of it this is a family dispute – and it makes me really really sad that we are sitting here today…

“I know some people want history to repeat itself, which I think is pretty dark… I’m not going to share at this point.”

Which is another dreadful, stupid, unsubstantiated thing to say.

There are theories, which do hold water, that Harry and Meghan’s only currency is that they are in the public eye, that loved ot loathed they must remain high profile celebrities. It’s the only way Meghan can sell her jars of over-priced jam.

But I, for one, have had enough of this pair of grifters.

I live in Sussex and am starting a campaign to have the word Sussex stripped from their titles – the attachment sullies our beautiful county.

The so-called Sussexes do nothing for the county and they do nothing for the country.

Maybe we should have a national competition, along the lines of Boaty McBoatface, to decide what this pair should be Duke and Duchess of? Sweet Fanny Adams perhaps?

Yes, Duke and Duchess of Sweet Fanny Adams might just fit the bill.
