The Tswaing Local Municipality council consists of twenty-eight members elected by mixed-member proportional representation. Fourteen councillors are elected by first-past-the-post voting in fourteen wards, while the remaining fourteen are chosen from party lists so that the total number of party representatives is proportional to the number of votes received. In the election of 1 November 2021 the African National Congress (ANC) won a majority of nineteen seats.
