The endorsements follow a similar confidence booster from National Assembly Speaker Baleka Mbete on Saturday. Mbete had also campaigned to take over from President Jacob Zuma but did not garner enough votes from branches in the nine provinces.
Four provinces were still due to vote in Nasrec‚ Soweto‚ on Monday morning‚ namely the Eastern Cape‚ Gauteng‚ Limpopo and KwaZulu-Natal. Voting results are expected in the afternoon.
Around 4‚700 delegates are expected to make their mark.
The conference‚ which started on Saturday‚ got off to a shaky start after disputes over accreditation delayed the programme by a day.
