African National Congress (ANC) MP Makhosi Khoza, a strident critic of scandal-plagued President Jacob Zuma, quit South Africa’s ruling party on Thursday, labeling Nelson Mandela’s 105-year-old liberation movement “alien and corrupt”. The 47-year-old Zulu linguistics expert, an ANC supporter since the age of 12, denounced Zuma in July as a “dishonorable and disgraceful leader” due to the litany of scandals he has attracted during his eight years in power.
