Suzette Little says she resigned as a DA councillor because she could no longer tolerate the double standards and strong-arm tactics used by the party.
Little is one of five City of Cape Town councillors who tendered their resignations on Thursday.
She resigned from the party and from the council.
She claims that councillors were forced to agree to an investigation into outgoing Cape Town Mayor Patricia De Lille.
Little says DA leader Mmusi Maimane threatened their jobs if they didn't toe the party line in previous council votes.
She alleges that the deputy chairperson of the DA's federal council, Thomas Walters, was appointed to keep tabs on council members and conduct surveillance on their social media.
Little claims council members in favour of De Lille were specifically targeted.
She says that De Lille and her perceived supporters within the caucus were victimised.
DA chief whip Shaun August also resigned on Thursday, saying he can no longer tolerate what's happening to De Lille.
He resigned as whip, councillor and DA member.
Other councillors who resigned in support of the outgoing mayor include Mayco member Siyabulela Mamkeli and ward councillors Greg Bernardo and Thulani Stemele.
