JB Marks Municipality (Tswana: Mmasepala wa JB Marks; Afrikaans: JB Marks Munisipaliteit) is a local municipality within the Dr Kenneth Kaunda District Municipality, in the North West province of South Africa. It was established after the August 2016 local elections by merging the Tlokwe and Ventersdorp municipalities.[5] The merger of the municipalities was motivated by political interests as the African National Congress was losing support to the Democratic Alliance in Tlokwe.
The municipality was renamed after JB Marks in 2017, following the creation of the new municipality the year before. Other name proposals included Josie Mpama.[6] Marks was born in Ventersdorp while Mpama was born in Potchefstroom.
See main article: JB Marks Local Municipality elections. The municipal council consists of seventy-seven members elected by mixed-member proportional representation. Thirty-four councillors are elected by first-past-the-post voting in thirty-four wards, while the remaining thirty-three 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) lost their majority on the municipal council.
The following table shows the results of the election.[7]
