Prince Harry has been sued for defamation by a charity he helped create to honor his late mother, Princess Diana. According to court records viewed by the Associated Press on Friday, April 10, Sentebale has accused Harry, 41, and friend Mark Dyer, who was a trustee for the organization, of either libel or slander. The lawsuit was filed in London's High Court last month, per the outlet. "As Sentebale's co-founder and a founding trustee, they categorically reject these offensive and damaging claims," a spokesperson for the Duke of Sussex and Dyer said in a statement to Us Weekly on Friday.
