A charity co-founded by Prince Harry in honor of his late mother, Princess Diana, from whom he resigned following a high-profile dispute, is suing the British royals for defamation at the High Court in London, a court filing showed on Friday.
Harry, King Charles’ youngest son, co-founded it in 2006 to help young people with HIV and AIDS in Lesotho and Botswana, but resigned as patron in March 2025 after a public dispute with its board chair, Sophie Chandauka.

According to a record made public on Friday, Sentebale filed a defamation lawsuit last month in the High Court against Harry and one of his close friends, Mark Dyer, who was also a trustee of the charity.

There were no details about what the lawsuit involved.
Neither Harry’s spokesperson nor the charity immediately responded to a request for comment.
The charity’s co-founder, Prince Seeiso of Lesotho, and the board of trustees joined Harry in abandoning Sentebale, which he helped create nine years after Diana died in a car crash in Paris and which means “forget me not” in the local language of Lesotho, southern Africa.
The 41-year-old prince called the breakdown of his relationship with Chandauka devastating, while she reported him and the trustees to Britain’s charities regulator for alleged harassment and bullying.
After a review, the Charity Commission reported that it had found no evidence of bullying, but said there had been weak governance and criticized all parties for allowing an internal dispute to become public.
