JOHANNESBURG - Barclays Africa and Standard Bank said on Monday they would stop working with McKinsey, a further blow to the global consultancy as it faces allegations of bribery for work done with friends of President Jacob Zuma.





Privately-held McKinsey, the world’s largest management consultancy, has denied doing anything illegal but said this month that it was embarrassed by mistakes it made while working with South African state utility Eskom last year.
