A recent slew of arrests linked to corruption is a much-needed show of teeth by authorities and a boost of confidence, the chief executive of Business Leadership South Africa has said. The African News Agency reports that in a column published on the website of the association of South Africa’s largest corporations and major multinational companies today, Busi Mavuso said stories of corruption at state institutions and in the private sector over the years had further depressed the growth potential of the struggling economy. Several people have been arrested, among them former government officials, in connection with a deeply flawed asbestos audit in the Free State province which resulted in the wastage of more than R200 million.
