City of Cape Town elections
# City of Cape Town elections

The council of the City of Cape Town in the Western Cape, South Africa is elected every five years by a system of mixed-member proportional representation. Half of the councillors are elected by first-past-the-post voting from individual wards, while the other half are appointed from party lists so that the total number of party representatives is proportional to the number of votes received. By-elections are held to replace the councillors elected by wards if a vacancy occurs.
