Johannesburg mayor Herman Mashaba has resigned from his position and the Democratic Alliance.
The resignation comes after former DA leader Helen Zille on Sunday won the vote for the powerful federal council chairperson position.
Reports say Mashaba told a number of Gauteng leaders on Saturday night that he would quit his job should Zille win the hotly contested battle, which is second to the party leader position.
About two hours after the announcement of Zille's victory, the City of Johannesburg issued a statement stating that Mashaba would be hosting a press conference on Monday morning.
Before this weekend’s election, Mashaba had publicly stated that he would quit if the DA was taken over by right-wing elements.
