Prince Harry’s former charity, Sentebale, is suing the Duke of Sussex for libel and slander one year after he resigned as its patron amid an ugly internal dispute with the charity’s chairwoman.
Page Six confirmed that Sentebale filed the defamation claim against Harry at the High Court in London on March 24.
The charity also sued one of the 41-year-old prince’s close friends, Mark Dyer, who served as a trustee of Sentebale before Harry and Dr. Sophie Chandauka’s falling out.
No further details about what the lawsuit entailed have been released.
A rep for the Duke of Sussex did not immediately respond to Page Six’s request for comment.
Harry co-founded Sentebale in Princess Diana’s honor in 2006. It focuses on helping young HIV and AIDS victims in the South African countries of Lesotho and Botswana.
However, the duke resigned from his role in March 2025 after clashing with Chandauka, who still serves as chair of the charity’s board.
Prince Seeiso of Lesotho, who co-founded Sentebale with Harry, and the board of trustees also left with the duke when he resigned last year.
“With heavy hearts, we have resigned from our roles as patrons of the organization until further notice, in support of and solidarity with the board of trustees,” Harry and Seeiso said in a joint statement at the time.
“It is devastating that the relationship between the charity’s trustees and the chair of the board broke down beyond repair,” they added.
Chandauka then reported both Harry and the trustees to the regulatory Charity Commission for England and Wales over shocking allegations of bullying and harassment.
She also alleged that the pair’s conflict began when Harry’s team asked her to defend his wife, Meghan Markle, from negative media coverage connected to an awkward photo op at a Sentebale event in April 2024.
“I said no, we’re not setting a precedent by which we become an extension of the Sussex PR machine,” Chandauka told the Financial Times in a March 2025 interview.
But the Commission discovered no evidence of “widespread or systemic bullying, harassment, misogyny or misogynoir” at the Sentebale charity in an August 2025 statement.
Still, the Commission criticized both Harry and Chandauka for allowing their dispute “to play out publicly” and noted that their “failure to resolve disputes internally severely impacted the charity’s reputation and risked undermining public trust in charities more generally.”
An insider close to the Duke of Sussex, meanwhile, claimed that neither Harry nor Seeiso could envision returning to Sentebale as long as Chandauka remained the charity’s chair.
