ANC chief whip Pemmy Majodina said Zwane would contact Paul Mashatile’s office about resigning.
According to Times Live, Majodina says Zwane, a Free State MEC, has agreed to appear before the ANC’s integrity commission.
The step-aside rule was adopted at the party’s 54th national conference in 2017, but ANC members say it’s “killing” the ruling party.
Zwane appeared in court and was granted R10,000 bail.
The fmr mineral resources and energy minister was arrested along with former Gupta employees Ugeshni Govender and Ronica Ragavan.
The trio faces fraud, theft, money laundering, and corruption charges in relation to the Estina dairy farm project in the Free State, in which public funds meant to empower black farmers were looted.
Zwane was the province’s agrarian and rural development MEC at the time.
The dairy project has been accused of state capture after it was revealed to be a cover for laundering money and the funding source for the Guptas’ lavish 2013 wedding.
Sindisiwe Seboka, the NPA’s Investigating Directorate spokesperson, said 15 people were involved, and much more arrests were expected.
Case postponed until November 2022.
