The chairwoman of a charity co-founded by the Duke of Sussex has called his brand "toxic" and claimed it hindered the group, after he and several others quit the organisation earlier this week. Speaking to the Financial Times, Dr Sophie Chandauka also said she first felt tensions between Prince Harry and herself a year ago. The duke resigned from Sentebale, a charity he set up nearly 20 years ago in honour of his mother Diana to help people in southern Africa living with HIV and Aids, after a row between the trustees and Dr Chandauka.
