Britain’s Prince Harry said he was “in shock” after quitting as a patron of Sentebale, a British charity he set up to help young people with HIV and AIDS in Lesotho and Botswana, following a row between trustees and the chair of the board.

The Duke of Sussex along with Prince Seeiso of Lesotho, who co-founded Sentebale in 2006, said in a joint statement Tuesday they had quit “with heavy hearts” as patrons in support of the trustees in their dispute with chairwoman Sophie Chandauka.
