The highest organ of a Marxist–Leninist governing party is the party congress. The congress elects the central committee and either an auditing commission and a control commission, or both, although not always. The central committee is the party's highest decision-making organ in between party congresses and elects a politburo and a secretariat amongst its members as well as the party's leader. When the central committee is not in session, the politburo is the highest decision-making organ of the party and the secretariat is the highest administrative organ. In certain parties, either the central committee or the politburo elects amongst its members a standing committee of the politburo which acts as the highest decision-making organ in between sessions of the politburo, central committee and the congress. This leadership structure is identical all the way down to the primary party organisation of the ruling party.
