An attorney specialising in medical law says a medical practitioner can divulge patient information, but only if it's factually correct and in the public interest. Adele van de Walt was reacting to accusations that retired Defence Force surgeon-general, Dr Veejay Ramlakan, broke doctor-patient confidentiality in his book, 'Mandela's Last Years'. Ramlakan's publisher, Penguin Random House, has withdrawn the book in the face of threatened legal action by Mandela's widow, Graca Machel. Van de Walt has told Prabashini Moodley of Lotus Radio in Durban that there are certain exceptions to the rule.
