A charity co-founded by Prince Harry in Africa to honor his late mother, Princess Diana, has sued him for defamation after he stepped down as a patron last year.

Sentebale, which supports young people living with HIV in Botswana and Lesotho, filed suit last month in London’s High Court against Harry and his friend, Mark Dyer, a former trustee at the charity. Court records viewed Friday indicate the lawsuit alleges either libel or slander, though specific documents detailing the claims were not available.

In a statement published on its website Friday, Sentebale explained its legal action: “The charity seeks the court’s intervention, protection, and restitution following a coordinated adverse media campaign conducted since 25 March 2025 that has caused operational disruption and reputational harm to the charity, its leadership, and its strategic partners.”

A spokesperson representing both Harry and Dyer has firmly denied the allegations, stating that the pair “categorically reject these offensive and damaging claims.”

This legal battle places the Duke of Sussex in an unusual position as a defendant rather than a plaintiff in the High Court. Over the past three years, Harry has been the primary claimant in several high-profile invasion of privacy lawsuits against Britain’s most prominent tabloids, alleging phone hacking and unlawful surveillance by journalists and private investigators.

The charity at the center of the dispute holds special significance for the prince. Harry co-founded Sentebale, which means “forget me not” in the language of Lesotho, approximately 20 years ago alongside Prince Seeiso of Lesotho. The organization was established to honor Princess Diana, who was a prominent advocate for HIV and AIDS treatment and worked tirelessly to reduce the stigma surrounding the disease.

Tensions within the charity reportedly began to surface in 2023 over disagreements regarding a new fundraising strategy. The situation deteriorated to the point where both founders stepped down as patrons in March 2025, expressing solidarity with trustees who had previously resigned.

At the time of their departure, Harry and Prince Seeiso indicated that the relationship between the board and its chair, Sophie Chandauka, had become irreparable. Chandauka subsequently accused Harry of orchestrating a campaign of bullying and harassment aimed at forcing her out of her position.

As the dispute unfolded publicly, Chandauka told Sky News that filming for one of Harry’s Netflix programs had interfered with a scheduled Sentebale fundraiser. She also claimed that an incident involving his wife, Meghan, the Duchess of Sussex, had become a source of friction within the organization.

The Charity Commission for England and Wales launched an investigation into the matter and ultimately criticized both sides for allowing the dispute to become public, damaging the organization’s reputation. However, the commission found no evidence to support allegations of widespread bullying or misogyny within Sentebale.

“Sentebale’s problems played out in the public eye, enabling a damaging dispute to harm the charity’s reputation, risk overshadowing its many achievements, and jeopardizing the charity’s ability to deliver for the very beneficiaries it was created to serve,” said commission CEO David Holdsworth in a statement released in August 2025.

Following the commission’s report, Harry’s spokesperson expressed criticism of its findings, while Chandauka welcomed the conclusions.

This legal battle represents a significant escalation in an already public dispute involving one of Harry’s most personal charitable endeavors. The case could potentially further complicate the Duke’s relationship with charitable organizations in the UK and Africa, especially those connected to his mother’s legacy.

The lawsuit also comes at a time when Harry and Meghan continue to develop their post-royal identity and charitable focus through their Archewell Foundation, based in the United States, where the couple now resides after stepping back from royal duties in 2020.
