The Umsobomvu Local Municipality council consists of thirteen members elected by mixed-member proportional representation. Seven councillors are elected by first-past-the-post voting in seven wards, while the remaining six 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 seven seats.
