A furious Prince Harry has lashed out, blaming the unprecedented letter from his father for a major hit to his signature charity.

It came as the prince’s expensive worries – from legal to public relations – keep mounting on several fronts.

Early on Wednesday (British time), Uganda dropped a bombshell announcement that it was quitting the Invictus Games. It came less than 48 hours after the letter from Buckingham Palace, authorised by the King, that spelled out the Duke and Duchess of Sussex’s continued status as non-working royals.

“In order not to be construed as being opposed to His Majesty King Charles III of the United Kingdom, whom we deeply revere, Uganda hereby withdraws from the Invictus Games,” General Muhoozi Kainerugaba, the son of Ugandan President Yoweri Museveni and head of the country’s armed forces, announced via X.

“We shall not participate in anything that does not have His Majesty’s approval.”

Kainerugaba went further later in the day.

“I have factions in the Ministry of Defence that support that Harry-Meghan nonsense,” he told The Times.

“I had to quash it straight away. I support the monarch. Period.”

Earlier this week, the King had made clear in the public letter that the status of Harry and wife Meghan Markle was unchanged, despite their return to Britain two weeks ago.

The letter sent to senior British officials said the couple’s charity work was “a personal matter for them and undertaken in their private capacity”.

It didn’t take long for the Sussex camp to hit back, first declaring Harry and Meghan’s “surprise” at the lack of notice. There was more after the Uganda news.

“Intended or unintended, this is clearly a consequence of the Lord Chamberlain’s guidance regarding the Duke and Duchess of Sussex that was rushed out without consultation on Monday,” a source close to Harry told Britain’s ITV on Wednesday (local time).

“Sadly, the only people who will suffer are the Invictus Games competitors.”

Uganda was the most recent country to join the Invictus Games, the international multisport event for wounded veterans founded by the Duke of Sussex in 2014. It was only the second African nation to join.

Invictus is one of the few major organisations that Harry has continued to work with even after stepping back as a working royal six years ago.

Prince Harry will likely have a share of multimillion-pound legal bill after his latest court loss.

Eye-watering legal bill

Money is also an issue elsewhere for Harry. Last month, he was ordered to pay millions of pounds in legal bills over his failed privacy case.

The prince and other high-profile claimants will have to cover the legal costs of a major British newspaper publisher after a ‌judge ruled their failed lawsuits were conducted in an unreasonable way.

Justice Matthew Nicklin has already ordered an interim payment of £9.54 million ($17.88 million) for the legal costs of Associated Newspapers, which publishes The Daily Mail and other titles.

Associated Newspapers has said it spent more than £34 million ($65 million) during the case. That means Harry and his co-complainants could be liable for as much as a further £25 million ($47 million).

Both sides have until October 2 to lodge permission to appeal the trial judgment or the costs ruling.

Sentebale sues

Then there is the trouble at Sentebale, one of the prince’s oldest charitable ventures, which is suing him for defamation.

Harry co-founded Sentebale with Prince Seeiso of Lesotho in 2006 ‌to help young people with HIV and AIDS in Lesotho and Botswana. He, Seeiso and much of the organisation’s board resigned in March 2025 after a public falling-out with chair Sophie Chandauka.

Earlier this year, Sentebale lodged a defamation claim in Britain’s High Court ‌against Harry and ⁠one of his close friends Mark Dyer, another charity trustee.

It sought “intervention, protection, and restitution” following an “adverse media campaign” that had “caused operational disruption and reputational harm to the charity, its leadership, and its strategic partners”.

“The proceedings have been brought against Prince Harry and Mark Dyer, identified through evidence ⁠as the architects of that adverse media campaign, ‌which ​has had significant viral impact and triggered an onslaught of cyber-bullying directed at the charity and its ​leadership,” the charity’s ‌statement said.

Harry has not commented on that case.

He also recently quit the board of African Parks, an unrelated conservation organisation that manages protected areas across 13 African countries. It has faced allegations of human rights abuse allegations and expulsion from Chad.

The duke, who was once African Parks’ president, left the board amid a broader governance reshuffle.

Harry and Meghan’s return to Britain with their young children has reignited the security debate.

And the big one: Security

Harry continues to fight for the level of taxpayer-funded security for his family that they had before “Megxit”.

The couple’s return to Britain, with children Archie and Lilibet, has reignited the debate that Harry has long styled as a “deal-breaker”.

“I can’t see a world in which I would bring my wife and children back to the UK at this point,” he told the BBC after losing a court battle in 2025.

This week, RAVEC – the British government’s Executive Committee for the Protection of Royalty and Public Figures – had been due to meet to consider a review of the Sussexes’ security now they are living in Britain.

It was delayed, without any public explanation.

The King’s letter, meawhile, made it clear that there is no change from the palace’s end – any security concerns should be taken to “the relevant police authorities”, it said.
