South African Deputy President Cyril Ramaphosa on Wednesday acknowledged receipt of a petition calling for President Jacob Zuma to resign.
The petition relates to proceedings in Parliament on August 8 when a motion of no confidence against Zuma is conducted, Ramaphosa said.
The matters raised in the petition will be dealt with by the National Assembly on August 8, Ramaphosa said.
The petition was delivered by opposition Democratic Alliance (DA) leader Mmusi Maimane earlier in the day.
Opposition parties have been pushing for a motion of no confidence by secret ballot in the hope that ANC MPs would be encouraged to vote against Zuma.
Parliament Speaker Baleka Mbete has yet to decide whether the no-confidence vote should be conducted through secret ballot.
Zuma, who has survived seven votes of no confidence, said recently he is confident to defeat another no confidence motion.
The 400-member Parliament is dominated by ANC MPs.
Toppling Zuma requires 50 of the 249 ANC MPs to support the no-confidence motion. Enditem
