[1] Under Marien Ngouabi, he was included on the five-member Executive Committee of the ruling National Revolutionary Council (CNR) as President of the Organization Commission on 21 June 1969.
[5] In 1979 Lekoundzou was again elected to the PCT Political Bureau;[1][6] at that point the body consisted of ten members, and he was assigned responsibility for planning and the economy.
[1] After Sassou Nguesso returned to power in October 1997 at the end of the 1997 civil war, Lekoundzou was appointed Minister of State for Reconstruction and Urban Development on 2 November 1997.
[20] On 31 January 2006, Lekoundzou was flown to France for emergency medical treatment due to a "cerebral affliction", while one of his aides also fell ill; some suspected that they were victims of poisoning.
The situation was at least superficially resolved by December 2006, when a party congress involving both factions was held; Lekoundzou was elected to the Political Bureau, but the power of the conservatives in general was weakened.
[20] In an early 2007 interview, Sassou Nguesso said that Lekoundzou, who had been living in France for some months, was there for health reasons as far as he knew, not as a result of any bitterness between them.
[22] Lekoundzou was still in France due to illness when the June 2007 parliamentary election was held,[23] but he nevertheless stood for re-election to the National Assembly as the PCT candidate in Boundji constituency.
