Prince Harry says he does not know how long King Charles has left to live in an emotional interview after losing his appeal in court over his security.

The Duke of Sussex claimed his father is not speaking to him because of his battle over taxpayer-funded police bodyguards.

He said there had been ‘so many disagreements, differences between me and some of my family’, as he admitted he couldn’t see a world in which his family would return to the UK.

But, amid another devastating broadside reopening wounds with the Royal Family, Harry told the BBC in California that he wants ‘reconciliation’.

‘He won’t speak to me because of this security stuff,’ the prince said, adding he didn’t know how long the King had left to live.

It comes just days after the King described the ‘daunting’ and ‘frightening’ experience of being told you have cancer, speaking in his most poignant update on his illness since being diagnosed 15 months ago.

The King, 76, is still undergoing regular treatments as someone ‘living with cancer’, although aides have previously said his recovery continues in a ‘very positive direction, as reflected with the very full national and international diary programme’ he is undertaking.

He said: ‘There have been so many disagreements, differences between me and some of my family this current situation that has been now ongoing for five years with regards to human life and safety is the sticking point it is the only thing that’s left.

‘Of course, some members of my family will never forgive me for writing a book, of course they will never forgive me for lots of things.

‘But you know there is, I would love reconciliation with my family there’s no point in continuing to fight anymore, as I said life is precious. I don’t know how much longer my father has, he won’t speak to me because of this security stuff but it would be nice to reconcile.

‘As I learnt through the First Nations, throughout Canada because of the Invictus games their goal in life was always truth and reconciliation and I turned around to them in many conversations and I said reconciliation can’t come without truth.

‘I’ve now found out the truth I’ve shared some of it with you today, a lot of it exists out there whether people choose to ignore it or not so it would be nice to have that reconciliation part now if they don’t want that, that’s entirely up to them.’

The King was diagnosed with an undisclosed form of cancer in January last year following routine surgery for an enlarged prostate.

Buckingham Palace have not confirmed what form he has, but have ruled out it being connected with his prostate issue.

They have also not disclosed what treatment he is still undertaking.

But there is little doubt that Charles has been more open about his diagnosis and medical treatment than any other monarch in history, using his profile to raise awareness of the disease.

In an emotional interview with the BBC, Harry said he was ‘devastated’ after sensationally losing his court fight – putting him on the hook for £1.5million in legal costs.

Asked if he had pleaded with the King to intervene, he added: ‘I never asked him to intervene – I asked him to step out of the way and let the experts do their jobs.’

But he added: ‘There is a lot of control and ability in my father’s hand, ultimately this whole thing could be resolved through him not necessarily by intervening but by stepping aside allowing the experts to do what is necessary and to carry out an RMB.’

The Duke of Sussex returned to London for the appeal

England’s second most senior judge, Sir Geoffrey Vos, told the duke his ‘grievance’ over downgraded security had not ‘translated into a legal argument’.

And he ruled the security decision had been a ‘predictable’ and even ‘sensible’ reaction to Megxit when Harry stepped back from being a senior royal and quit Britain.

Saying that he felt ‘let down’ and looking upset, he described his court defeat as a ‘good old-fashioned establishment stitch up’ and blamed the Royal Household for influencing the decision to reduce his security.

It comes as Harry today sensationally lost his battle for taxpayer-funded armed police bodyguards when in the UK – putting him on the hook for £1.5million in costs.

The Duke of Sussex has been told that his ‘grievance’ over downgraded security had not ‘translated into a legal argument’ to successfully challenge the decision.

Harry believes he has been ‘singled out’ and ‘badly treated’ for ‘unjustified, inferior treatment’ since Megxit five years ago.

His barrister argued that the removal of Met Police armed bodyguards when he is in the UK has left the royal’s life ‘at stake’.

The California-based royal had fought the dismissal of his High Court claim against the Home Office over the decision of the Executive Committee for the Protection of Royalty and Public Figures (Ravec) that he should receive a different degree of protection when in the country.

But Sir Geoffrey Vos, Master of the Rolls said in his ruling this afternoon in London that Ravec’s decision ‘were taken as an understandable, and perhaps predictable, reaction to the claimant having stepped back from royal duties and having left the UK to live principally overseas’.

‘These were powerful and moving arguments and that it was plain the Duke of Sussex felt badly treated by the system’, he said.

‘But I concluded, having studied the detail, I could not say that the Duke’s sense of grievance translated into a legal argument to challenge RAVEC’s decision’.

Sir Geoffrey said Harry ‘makes the mistake of confusing superficial analogies’ when comparing himself with other VIPs which had ‘added nothing’ to the legal question.

He added: ‘My conclusion was that the Duke of Sussex’s appeal would be dismissed’.

It means that for now, armed police bodyguards, paid for by the British taxpayer, will not be automatically reinstated for him, Meghan, Archie and Lilibet when they are in the UK. It raises more questions over whether the Sussexes will visit Britain again.

The King and his youngest son are believed to have differing views over Harry’s decision to pursue his legal fight with the Home Office. The Home Secretary is calling for the duke to pay all costs for both sides – a bill approaching £1.5million.
