Members of the South African Communist Party (SACP) and attendees of the Memorial of the late anti-apartheid activist Ahmed Kathrada protest outside the Johannesburg City Hall as they call for President of South Africa Jacob Zuma to step down on April 1, 2017 in Johannesburg. The Ahmed Kathrada Foundation holds a memorial service for the anti-apartheid stalwart, after the government called off a planned event to commemorate him. The event comes days after President Jacob Zuma's shock sacking of finance minister Pravin Gordhan in a cabinet purge that has plunged the ruling ANC into chaos. / AFP PHOTO / GULSHAN KHAN (Photo credit should read GULSHAN KHAN/AFP/Getty Images)
