Early Life and Journalism
Zille was born in Johannesburg on March 9, 1951, and earned a B.A. at the University of the Witwatersrand. From 1974 to 1982 she worked as a political journalist at the Rand Daily Mail, where, according to Britannica, she led the newspaper’s investigation into the 1977 death in police custody of Steve Biko, which found evidence of brain damage and a likely beating, contrary to the government’s account.
Early Career
In 1989 she opened a public policy firm and became its senior partner. She served as director of communications at the University of Cape Town from 1993 to 1999 and, in the early 1990s, as a technical adviser to the Democratic Party during the CODESA negotiations. She joined the Democratic Party in 1995.
Rise Through the DA
Zille was elected to the Western Cape provincial parliament in 1999, serving as the province’s education executive council member from 1999 to 2001 and as opposition leader in the legislature from 2001 to 2004. She then served in the National Assembly (2004–2006) and as the DA’s national spokesperson in 2004. In 2006 she became Mayor of Cape Town, leading a coalition of seven parties until 2009. She was elected leader of the Democratic Alliance in 2007, holding the post until 2015, and served as Premier of the Western Cape from 2009 to 2019. In October 2019 she was elected chairperson of the DA’s Federal Council.
Controversies
In 2014, merger talks between the DA and Agang SA, led by Mamphela Ramphele, collapsed shortly after being announced. In March 2017, Zille posted comments about colonialism on Twitter that prompted backlash; in June 2017 the DA suspended her from party activities and scheduled a disciplinary hearing, and before it took place she and the party reached a settlement under which she apologised, resigned from the DA’s decision-making structures, and the party halted further disciplinary action.
Johannesburg Mayoral Bid
In September 2025, the DA named Zille as its candidate for Johannesburg mayor in the 2026 local government elections, a nomination that drew political backlash from critics, according to Cape Times and Cape Argus coverage. Campaigning under #BelieveInJoburg, she set priorities of reliable water and electricity and repairing roads, traffic lights and street lighting, and her campaign became known for stunts including swimming in potholes and rowing a boat on a waterlogged street. Pre-election commentary was mixed, with Daily Maverick and Business Day analysis describing the DA’s path to a Johannesburg majority as uphill.
2026 Election Results and Coalition Talks
As of about 10pm on November 5, 2026, results reported for Johannesburg showed the DA on 40.98%, the ANC on 16.47%, ActionSA on 16.35%, the EFF on 7.19% and the MK Party on 5.47%, with provisional results at that stage suggesting a hung council. ActionSA leader Herman Mashaba said his party was “willing to engage with any political party.” Zille said the party with the most votes should lead the municipality, that she would join only a “stable” and “governable” government, and that negotiations were being conducted nationally. On November 7 she said she preferred ActionSA or the ANC as partners, favoured a coalition “as big as necessary but as small as possible,” and dismissed suggestions that a DA administration would cut social grants. These are provisional results; as of this writing, final results and the composition of any governing coalition had not been confirmed.
