Kamougué was also President of the Union for Renewal and Democracy (URD) political party, and he was appointed as Minister of National Defense in April 2008.
He was Minister of Foreign Affairs from 1975 to 1978 as well as a member of the Higher Military Council (Conseil supérieur militaire, CSM) under Head of State Félix Malloum.
[6] Kamougué was appointed as Minister of Civil Service and Labor in April 1993, as part of the transitional government formed after the Sovereign National Conference.
[13] The URD decided against boycotting the election and nominated Kamougué as its candidate at an ordinary party congress in early April.
In the April 2002 parliamentary election, he was re-elected to the National Assembly as an URD candidate from Sarh constituency in Barh Köh Department.
[17] It was initially reported that Kamougué was one of the opposition leaders arrested during a battle between government forces and rebels in N'Djamena in early February 2008.
On February 16, 2008, Minister of Communications Hourmadji Moussa Doumgor denied this, saying that Kamougué had not been arrested and that he was "hiding in the country's interior".
