Prince Harry faces a massive legal challenge as Sentebale, the charity he co-founded in 2006, files a defamation lawsuit in London’s High Court. The legal action marks a dramatic escalation in a long-standing dispute between the Duke of Sussex and the organization’s leadership. Filed on March 24, the claim names both the prince and former trustee Mark Dyer as defendants in a case that threatens to overshadow the charity’s mission in Southern Africa.
Prince Harry and the Sentebale Defamation Lawsuit
The High Court records indicate that the lawsuit centers on allegations of a “coordinated adverse media campaign” orchestrated by Prince Harry and Dyer. Sentebale officials claim this campaign, which allegedly began in March 2025, caused significant operational disruption and reputational harm. The charity asserts that the defendants acted as the “architects” of false narratives that triggered viral cyberbullying against the board and executive leadership.
This legal battle follows years of tension between the founders and the current chair, Dr. Sophie Chandauka. A lawyer appointed in 2023, Chandauka became the focal point of a governance row that eventually led to the resignation of Prince Harry and his co-founder, Prince Seeiso of Lesotho, as patrons. The fallout also saw several trustees quit their positions, citing a loss of confidence in the board’s direction.
The Breakdown of a Royal Partnership
Sentebale, which means “forget-me-not” in the Sesotho language, began as a deeply personal project for the Duke. He established the organization in memory of his mother, Diana, Princess of Wales, to support vulnerable children and young people affected by HIV/AIDS in Lesotho and Botswana. For nearly two decades, the prince served as the public face of the charity, frequently participating in the annual Sentebale Polo Cup to raise millions in funding.
However, the relationship soured following the introduction of a new fundraising strategy in the United States. Internal disagreements regarding executive management and governance structures quickly turned into a public war of words. In August 2025, the Charity Commission released a report criticizing all parties involved for allowing the dispute to play out in the media. While the regulator cleared the prince of racism allegations, it noted that the public row “severely impacted” the charity’s reputation.

Allegations of Cyberbullying and Misogynoir
The current lawsuit highlights the intensity of the conflict. Sentebale’s leadership claims that the adverse media campaign forced them to divert critical resources away from their charitable work to manage a reputational crisis. Dr. Chandauka previously described the situation as a “story of a woman who dared to blow the whistle” on issues including abuse of power, harassment, and “misogynoir”—a specific form of discrimination against Black women.
In contrast, representatives for the Duke of Sussex categorically reject these claims. A spokesperson from The Office of the Duke and Duchess of Sussex described the lawsuit as “offensive and damaging.” They argued that the Charity Commission found no evidence of widespread bullying or harassment at the organization, as previously claimed by the chair. The spokesperson further lamented that charitable funds—though Sentebale claims the legal costs are covered by external donors—are being entangled in litigation rather than serving the children of Southern Africa.
Impact on Global Philanthropy
The litigation against Prince Harry comes at a time when his global philanthropic efforts are under intense scrutiny. As he continues to navigate various Royal Family Legal Battles in the UK courts, this specific case strikes at the heart of his charitable legacy. The diversion of leadership time and the potential for a lengthy trial could hinder Sentebale’s ability to maintain its strategic partnerships and donor relationships.
Sentebale maintains that the legal action is a necessary step to secure protection for its staff and leadership. The charity emphasizes that the “onslaught of cyberbullying” and the circulation of false narratives must stop to ensure the organization can continue its work. As the case moves forward in the High Court, the legal discovery process may reveal further details about the internal communications and the alleged “media campaign” that led to this unprecedented split between a royal founder and his own charity.

A Legacy at Risk
The Duke’s representatives continue to emphasize his commitment to the mission he started twenty years ago. They maintain that Sentebale remains a “deeply personal and transformative mission” for him. Despite the legal proceedings, the prince’s supporters argue that his actions were intended to protect the charity’s original vision from what they perceive as poor governance.
The High Court will now determine whether the actions of Prince Harry and Mark Dyer crossed the line into defamation. With no immediate documents available to the public, the legal community and royal observers await the next stage of the proceedings. The outcome will likely have lasting implications for how high-profile patrons interact with the boards of the charities they support, particularly when personal missions clash with corporate governance.
