Prince Harry is being sued for defamation by Sentebale, the charity he co-founded nearly two decades ago to honour Princess Diana's humanitarian legacy. The High Court action, filed in London in March 2026, names Harry and former trustee Mark Dyer as defendants.
Sentebale, a UK-registered charity co-founded with Prince Seeiso of Lesotho in 2006, alleges that the two men orchestrated an 'adverse media campaign' that caused operational disruption and reputational harm to the organisation, its leadership, and its strategic partners.
