The speaker of parliament said on Friday that Mr Zuma would face a fresh no-confidence motion on February 22.
President Jacob Zuma's future may well be decided today as the African National Congress's top six leaders prepare to meet him following the party's national working committee (NWC) decision that he should step down.
Mr Zuma, who has not said whether he will step down voluntarily before his second term as president ends, has been deserted by several prominent allies in the ANC since Mr Ramaphosa took over leadership of what is the only party to govern South Africa since the end of apartheid. Ramaphosa, 65, has been lobbying the ANC's national executive to force Zuma to resign.
Opposition parties have called for ANC leader and Deputy President Cyril Ramaphosa to replace Zuma, in time to deliver SONA.
Zuma is expected to deliver what is likely to be his final State of the Nation Address on Thursday.
Zuma's prolonged stay at the Union Buildings is seen by some as detrimental to uniting the party ahead of the crucial 2019 general elections.More news: CAS reinstates Russian athletes banned by the IOC
"They are saying as the ANC top six it would be ideal to deal with it before he faces a vote of no confidence".
Mr Zuma has survived several no-confidence votes during his rule thanks to loyal voting by ANC lawmakers, who form a strong parliamentary majority. Although Zuma retains the support of a faction within the ANC, he no longer holds a top post.
"We are not going to humiliate President Zuma; we are going to have a discussion on what is in the interest of the ANC and the economy", Mantashe said.
Until Zuma was recalled from office, action against state capture would be limited, and talk about eradicating corruption would remain hollow, and somewhat meaningless, FutureSA said. The Democratic Alliance was unsuccessful in its bid to have the Sona postponed.
The officials met Zuma at the Presidential Guesthouse on Sunday night.
