In the months following the elections, the political rivalry between Tshombe and the President of the Congo, Joseph Kasa-Vubu, grew increasingly tense. At the first session of the new Parliament on 13 October 1965, Kasa-Vubu unexpectedly announced that Tshombe's transitional government had fulfilled its purpose. He named Kimba the new Prime Minister and tasked him with forming a government of national unity. Kimba had little personal following or national reputation and thus was considered inoffensive to members of Parliament and of little threat to Kasa-Vubu's ambitions. Kasa-Vubu also hoped that by appointing another Katangese to the post, he would avoid aggravating persisting secessionist sentiment in Katanga. Kimba's government was installed on 18 October, representing 16 of the 39 political parties with members in Parliament.
