A charity co-founded by Prince Harry is suing ‌the British royal for defamation at the High Court in London, ​a court record shows.

Sentebale was founded by Harry in 2006 to help young people with HIV ‌and AIDS in Lesotho and Botswana, but he resigned as a patron in March 2025 after a public falling-out with the chair of the board, Sophie Chandauka.

According to a record made public on Friday, Sentebale lodged a defamation claim last month at the High Court against Harry and Mark Dyer, who was ‌also a trustee of the charity.

No documents are currently available in the claim, which was originally filed on 24 March.

Harry co-founded the charity, alongside Prince Seeiso of Lesotho, which was aimed at enhancing the lives of vulnerable children in the southern African country.

The pair both stepped down last year in a dispute with chairperson Dr Chandauka.

The initial rift emerged in 2023 after trustees began plans for a new fundraising strategy in the US.

The initial rift emerged in 2023 after trustees began plans for a new fundraising strategy in the US.

The “serious dispute” was exacerbated by strategic and financial difficulties for the charity following the COVID-19 pandemic, according to a report from The Charity Commission (CC).

The CC criticised both sides for allowing the dispute to be played out in public.

Commission CEO David Holdsworth said they enabled the rift to “harm the charity’s reputation”, which in turn jeopardised its “ability to deliver for the very beneficiaries it was created to serve”.
