'Charles will be devastated by Harry's harsh words - how can he ever trust him again?'

Bristling with anger, Prince Harry declared that he wanted to be reconciled with the rest of the Royal family. There was, he said, no point in continuing to fight. But, in what was another within a couple of hours of losing his court case over his security, he savaged the Royal household and accused his UK family of failing to keep him safe.

Harry clearly feels that there has been some sort of conspiracy first to stop him from leaving his royal role, and then to force him and his American family back to the UK. He accuses his royal relatives of being complicit in that conspiracy.

"Despite all our differences," he said, "don't you care about my safety"? Those are harsh words for a father to hear.

And the King, who is apparently no longer speaking to the son he used to call "my darling boy" must be devastated to hear him make such a blunt allegation.

Harry feels betrayed by his family, the household and the tabloids. And now he says "the other side have won in keeping me unsafe".

He says he can only come back to the UK with his family if he is invited because then he would get the security he believes he needs.

But this bombshell of an interview is unlikely to bring that invitation any closer. And that's because at the root of the rift is the question of trust.

Harry's father and brother do not trust Harry to keep conversations private. And this loudspeaker of a diatribe against them is not going to make them change their minds.
