Top officials in South Africa's ruling ANC party are divided over whether President Jacob Zuma should step down after multiple graft scandals. Zuma is due to deliver the annual state of the nation address to Parliament in Cape Town on Thursday, despite growing calls for him to quit before the speech. <br/><br/>The African National Congress' national executive committee will meet tomorrow, hours before the address. The party's Deputy Secretary-General, Jessie Duarte, today said the 80-member national executive committee is the ANC's highest decision-making body and could "recall" Zuma from the post of President.<br/><br/>Many ANC members are pushing for Cyril Ramaphosa, the new head of the party, to replace Zuma, 75, as president immediately. But Zuma loyalists have said that the serving president should complete his second and final term in office, which would end when elections are held next year.
