In the aftermath of the Pretoria Minute of August 1990, she was centrally involved in launching an ANC branch in Mafikeng (later renamed Mahikeng); she was elected to the branch's inaugural nine-member executive, chaired by Job Mokgoro.
[1] During South Africa's post-apartheid transition, she served as Deputy Mayor of Mafikeng, as well as a member of the National Executive Committee of the ANC Women's League.
[3] In late April 2003, Matsomela announced that she had resigned from the office and asked the ANC to appoint her to a new position elsewhere.
Her political adviser, Thami Mvambo, told the press that she had resigned in the "spirit of good governance" due to a long-running campaign by the ANC regional chairperson, Themba Gwabeni, to undermine and isolate Matsomela.
Instead, she was sworn in to the National Assembly on 2 September 2005,[6] filling the casual vacancy that arose when Mildred Mpaka resigned after being convicted of fraud in the Travelgate scandal.
