Mpho Phalatse has been voted out as City of Johannesburg executive mayor.
Councillors voted for her removal with 140 votes in support of the motion of no confidence.
A total of 129 councillors voted for Phalatse to remain in the role.
Earlier in the day, she said she was confident she would remain in office despite three motions of no confidence against her on Thursday.
She said the Democratic Alliance (DA) began its tenure in the City with 140 out of 270 seats for a DA-led multiparty government. In September, she was illegally booted from her position when some coalition parties crossed the floor.
Phalatse addressed rumours that she would join ActionSA if removed: "If I'm out of office, I will communicate the plans, but I still believe I will be in office [after the council meeting this week]."
She said action plans put in place by the DA-led government were not political.
"Whatever happens, whoever comes in, I hope they will have the sense to continue the plans. These are not political plans."
