On 10 January 2006, businessman Warren Clewlow, on the board of four of the top-10 listed companies in SA, including Old Mutual, Sasol, Nedbank and Barloworld, said that government should stop its unsuccessful behind-the-scenes attempts to resolve the Zimbabwean crisis and start vociferously condemning what was happening in that country. Clewlow's sentiments reflected the South African private sector's increasing impatience with Mbeki's "quiet diplomacy" and were echoed by Business Unity South Africa (BUSA), the umbrella body for business organisations in South Africa.
