Joseph Iléo (15 September 1921 – 19 September 1994), subsequently Zairianised as Sombo Amba Iléo,[1] was a Congolese politician and was prime minister for two periods.
Joseph Iléo was born on 15 September 1921.[2] In 1956, he was one of the authors of Manifeste de la Conscience Africaine, which demanded the right of Africans to self-rule.
In 1958, he was one of the founders of the Mouvement National Congolais. When the movement split a year later, he joined the camp led by Albert Kalonji.[3]
Iléo was voted into the Senate and then voted its president in June 1960. Upon the dismissal of then-prime minister Patrice Lumumba, Iléo was declared prime minister by Congolese president, Joseph Kasa-Vubu, on 5 September 1960. He held the post until 20 September 1960.[4]
Under Kasa-Vubu's successor, Justin Marie Bomboko, Ileo served as Minister of Information. He was again declared prime minister on 9 February 1961. He remained in this post until 2 August 1961.
From March to December 1979 Iléo served as President of the National Assembly.[2]
In April 1990, he founded the Parti Démocrate Social Chrétien, serving as chairman of the party until his death. He died on 19 September 1994, aged 73.[2]
