The Latest on South Africa's leadership crisis (all times local):
South Africa's ruling party is welcoming the resignation of President Jacob Zuma after months of growing public anger over multiple corruption allegations.
The African National Congress is expressing gratitude for Zuma's "loyal service" and is encouraging party members to support Cyril Ramaphosa, who is now the country's acting president.
Ramaphosa is expected to be elected swiftly in a parliament vote and sworn in.
South African President Jacob Zuma says he has resigned "with immediate effect."
The scandal-tainted leader made the announcement late Wednesday in a televised address to the nation.
Zuma says he has resigned despite his disagreement with the instruction of the ruling African National Congress party to leave office immediately. The ANC had been prepared to pursue a vote of no confidence in parliament on Thursday.
Zuma's tenure has been marred by years of corruption scandals.
South Africa is waiting for President Jacob Zuma to deliver the statement he had promised in response to the ruling party's order to resign.
The presidency had said Zuma would address the nation at the top of the hour but the podium shown on TV screens across the country remains empty.
The ruling African National Congress says it will move to oust the scandal-tainted Zuma in a parliamentary vote if he does not quit voluntarily.
That vote has been set for Thursday afternoon.

He says he will make a statement later.
South African President Jacob Zuma says ruling party leaders have not given him clear reasons for why he should resign and he calls his treatment "unfair."
Zuma broke his silence Wednesday in a live interview with state broadcaster SABC as the nation awaited word on whether he would obey a ruling party order to leave office.
Zuma says the ruling African National Congress has not followed party procedures in trying to unseat him. The ANC wants parliament to vote Thursday on a motion of no confidence if he doesn't resign Wednesday.

The president has not commented in the ongoing interview on whether he will resign.

The office of Baleka Mbete says the timing of the vote by open ballot must be agreed upon by the parliament's program committee at a meeting later Wednesday.
However, resistance to Mbete's plan is not likely. Both the ruling African National Congress party and opposition parties are pushing for a parliamentary vote against Zuma, who has not responded to an order from his own party to leave office.
An opposition-sponsored vote of no confidence against Zuma had been scheduled in parliament for Feb. 22, but opposition parties wanted the event to be moved to this week.

Mashatile says Zuma faces a deadline Wednesday to respond to a ruling party order to leave office.
"We can no longer keep South Africa waiting," Mashatile says.
Zuma has been discredited by corruption scandals. Police have raided the home of a prominent business family with links to the president.
South African police have raided the residential compound of a business family suspected of using its ties to President Jacob Zuma to influence Cabinet appointments and land state contracts.
Agents from the Hawks, an elite police investigative unit, on Wednesday entered the compound of the Gupta family in Saxonwold, an affluent neighborhood in Johannesburg.
The raid happened as the ruling African National Congress Party awaited a response from Zuma after instructing him on Tuesday to quit office because of a series of scandals.
The Gupta business family has been a flashpoint for national anger over corruption in state enterprises during Zuma's tenure. A judicial commission is preparing to investigate the alleged graft.
Zuma and the Guptas deny wrongdoing.
