There has been widespread speculation in local media that the African National Congress' (ANC) 80-member Executive Committee passed a resolution this week calling for the removal of Zuma as South African president. "I would say Zuma will be gone in anything between 10 and 30 days maximum".
The South African delegation led by Ramaphosa included a broad range of leadership from various sectors of the economy and society, with Finance Minister Malusi Gigaba the lead minister and co-ordinator. He's also vowed to fight the graft that have marred Zuma's administration, Bloomberg said.More news: Russian Federation investigators believe that mafia money funded Doonbeg
