FORMER president Nelson Mandela announced on Wednesday that the Heath special investigating unit would soon be restructured into a number of separate units. Speaking to journalists at his office in lower Houghton, Johannesburg, where he was visited by Judge Willem Heath, Mandela said the format of the restructuring would depend on discussions between Heath and Justice Minister Penuell Maduna. Mandela commended the unit for its successes in exposing corruption in the country. Despite recent criticism of the unit, Mandela said, the minister held Heath in the highest respect. “There has been debate over the jurisdiction (of the unit) but the minister appreciates what the judge has done.” Addressing journalists, Heath said he had come to visit Mandela as a friend he had known for four years, not as a politician.
