Sentebale, an AIDS charity cofounded by Prince Harry in honor of Princess Diana, has sued him for defamation in England's High Court. The charity claims Harry and Mark Dyer orchestrated an adverse media campaign since March 2025 causing reputational harm. Harry stepped down as patron last year following management disagreements. Harry's spokesperson rejected the claim as offensive and damaging. A UK Charity Commission inquiry found no evidence of bullying but criticized weak governance and all parties for publicizing internal disputes.
