South African President Jacob Zuma’s state of the nation speech in parliament has been postponed, as pressure grows on him to resign.
Parliament speaker BalekaMbete made the announcement, without giving a new date for the address that had been scheduled for Thursday.
The ruling ANC earlier called a meeting of the party’s top body for Wednesday to decide the president’s future.
Mr Zuma, 75, has resisted calls to quit over corruption allegations.
He was replaced as party leader by his deputy, Cyril Ramaphosa, 65, in December. He is now the front runner to succeed him as president.
Earlier on Tuesday, the Nelson Mandela Foundation urged Mr Zuma to step down.
South Africa had seen “systematic looting” under Mr Zuma’s rule, and he “must go sooner rather than later”, the foundation said in a statement.
