As confirmed by Page Six, the lawsuit was filed on March 24, and besides Harry, the humanitarian organization also sued his close friend Mark Dyer, a former trustee of Sentebale. The organization’s board of directors and CEO announced on Friday that they had initiated legal proceedings against Harry and Dyer over a coordinated negative media campaign that began in March 2025. They stated that the duo caused operational disruptions and reputational damage to the humanitarian organization, its leadership, and strategic partners, which, they claim, resulted in significant viral impact and triggered a wave of cyber violence directed at the charity and its leadership. On the other hand, a spokesperson for the Duke of Sussex and Dyer stated that the two categorically reject the allegations, calling them offensive and damaging claims. "It is extraordinary that charitable funds are now being used to initiate legal proceedings against the very people who built and supported the organization for nearly two decades, rather than being directed toward the communities the charity was founded to serve," the spokesperson added. Prince Harry co-founded Sentebale in 2006 in honor of his mother, Princess Diana. The organization focuses on helping youth affected by HIV and AIDS in Lesotho and Botswana. The conflict arose in March 2025, when Harry resigned following disagreements with the board chair, Sophie Chandauka. At that time, co-founder Prince Seeiso and the board of trustees also left the organization. "With heavy hearts, we are stepping back from our roles as patrons of the organization until further notice, in a show of support and solidarity with the board of trustees," Harry and Seeiso stated in a joint statement, adding that it is disheartening that the relationship between the trustees and the chair has been irreparably damaged. Subsequently, Chandauka reported Harry and the trustees to the Charity Commission for England and Wales over allegations of bullying and harassment. She also claimed that the conflict began when Harry’s team asked her to defend his wife, Meghan Markle, from negative media reporting related to a Sentebale event in April 2024. "I said no, we do not set a precedent where we become an extension of the Sussex PR machine," Chandauka told the Financial Times in March 2025. In August 2025, the Commission announced that it had found no evidence of widespread or systemic bullying, harassment, or misogyny within the organization. However, it criticized both Harry and Chandauka for allowing their dispute to play out publicly, warning that such an approach had seriously damaged the charity’s reputation and potentially undermined public trust. According to a source close to the Duke of Sussex, neither Harry nor Prince Seeiso are considering a return to Sentebale as long as Chandauka remains at the helm of the organization.
