The Mahikeng Local Municipality council consists of seventy members elected by mixed-member proportional representation. Thirty-five councillors are elected by first-past-the-post voting in thirty-five wards, while the remaining thirty-five 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 forty seats.
