Is Prince Harry happy? That’s what I get asked the most – and of course, it’s the million-dollar question.

He may live in a palatial Californian mansion, be free of the shackles (as he sees it) of royal duty and have a gorgeous wife, Meghan Markle, and children, Prince Archie and Princess Lilibet. But is Harry really happy?

Certainly, for much of the past six years since Megxit, he’s looked angry, stressed and emotional. Last month was a case in point.

As soon as he arrived in the UK, he learned he’d comprehensively lost his privacy case against the Daily Mail. Appearing onstage for what should have been a celebratory Invictus event, he looked nervous and slightly stunned.

Given Associated Newspapers Limited, the Mail’s publishers, are seeking costs against him (and others including Sir Elton John and Liz Hurley) in the region of £35 million – which could potentially bankrupt him – you can understand his anxiety.

There was all that drama about was he coming/was he not coming (when he didn’t get the security and gun cops he wanted), his family weren’t coming (due to the security), then his family DID come (except we never saw them – proving conclusively that it IS possible for them to come safely to the UK, despite Harry’s many and varied protestations that it’s not safe enough here).

Even at Birmingham’s NEC, when he was about to go to Highgrove for that much longed-for tea with his kids and the King, he looked (and sounded) somewhat flat.

For me, Harry looks as if he’s a man without a purpose.

I wrote last week about the shock bombshell that the Sussexes are considering moving back to the UK – and at the very least spending more time over here.

Harry misses his family and his pals. Yet he’s waged continual war on the British establishment – the government, the press, the judiciary and the monarchy itself.

I thought it was instrumental that when he was visiting last month, he appeared on Joe Marler’s podcast and gave his occupation as ‘Full-time dad. British Army veteran. Prince of England. Duke’.

We’ll leave aside the historical inaccuracy (there’s been no Prince or indeed King of England since the United Kingdom union in 1707), but it’s the apparent yearning that gets me. He doesn’t seem to know who or what he is.

So is he happy? I don’t think he truly is – but the sadness for Harry is that he’s searching for something he’s not going to find. So I’m not sure he ever will be.
