Meanwhile, the ANC in Gauteng had recommended three people for the position of provincial premier, with Mashatile its preferred candidate. The other two candidates were deputy ANC chairperson in the province Nomvula Mokonyane and deputy provincial secretary Mandla Nkomfe.
The party had resolved at its Polokwane conference to ensure gender parity in appointing premiers.
Each province submitted three names for premier.
