Dhaka, 15 Feb, Abnews: Jacob Zuma, South Africa's embattled and controversial president, has announced his resignation in a televised address to the nation.
"I have to come to decision to resign with immediate effect," he said late on Wednesday in Pretoria.
Zuma's resignation followed weeks of intense public pressure to step down amid longstanding corruption allegations.
The ruling African National Congress (ANC) formally asked Zuma, 75, to resign on Tuesday. He initially refused, saying he did not understand why he was being told to step down.
The party later announced plans to hold a no-confidence vote against him on Thursday in parliament.
"It is my party that placed me the representative of the people. It is my party that availed me," Zuma said in his speech from Union Buildings.
"Make no mistake, no leader should stay beyond the time the people they serve. No leader should seek an easy way out because they could face a life without the perks of political office."
Deputy President Cyril Ramaphosa, who is also the newly elected head of ANC, is expected to become acting president on Thursday.
A new president must be elected within 30 days but the cabinet and presidency continues.
Zuma, who served as the country's president since 2009, joined the ANC in 1958.
He is considered one of the party stalwarts, having served for 10 years on the Robben Island prison alongside freedom fighter Nelson Mandela and living in exile before returning to South Africa in 1990.
Despite being known for being an astute political operator, Zuma's presidency was characterised by scandal and corruption allegations, making him the most controversial president since the end of apartheid.
