McKinsey & Co. is partnering with South African business-lobby group Business Unity South Africa (Busa) to prepare for an event aimed at connecting global policymakers, civil-society organisations and business leaders that will form part of next year's Group of 20 (G20) gatherings. The partnership between the consulting firm and Busa comes after McKinsey this week agreed to pay more than $122-million to resolve criminal allegations tied to a corruption scandal. The impropriety involved former leaders of state-owned ports and rail operator Transnet during an era of endemic government graft, known locally as State capture.
