A group of African National Congress (ANC) members convened under the banner "defend Luthuli House" say a planned march in Johannesburg led by the Black First Land First (BLF) movement to support President Jacob Zuma's continued stay in office is misdirected.
Mr Zuma has not said whether he will step down voluntarily before his second term as president ends next year.
The speaker of parliament said on Friday that Mr Zuma would face a fresh no-confidence motion on February 22.
Party officials were mandated by the ANC national working committee last week to meet Zuma and ask him to step down, after a national executive committee meeting earlier agreed that the officials should manage his exit.
The rand, which tends to strengthen on signs Zuma could leave office, pared losses on the announcement from parliament.
Alleged corruption leads point to Zuma & friends
"They are saying as the ANC top six it would be ideal to deal with it before he faces a vote of no confidence". The ANC has the power to recall President Zuma from his duties as president of the country before the SONA address and send a clear signal that it is embarking on a new path - a path of true leadership, in tune with the needs of the people, and committed to good governance and the end of state capture. "The ANC top six have held them at president Zuma's guesthouse".
The ANC president said the party is already in campaign mode for the 2019 general election.
These opposition maneuvers, whose desire is to put Zuma out of the presidential chair as soon as possible, occur amid charges of alleged corruption against the head of State that come back to public light after the National Prosecution annulled a ruling of the High Court of Justice which had rejected those charges.
"For this to happen though, President Zuma must be prevented from delivering the SONA".
The upcoming motion of no confidence against President Jacob Zuma should be conducted through a secret ballot, EFF leader Julius Malema said on Saturday.
