 Within the party was established a Political Bureau ("Politburo") and Organisation Bureau ("Orgburo") to accompany the existing Central Committee; the decisions of these party bodies had to be adopted by Sovnarkom and the Council of Labour and Defence.Lenin was the most significant figure in this governance structure; as well as being the Chairman of Sovnarkom and sitting on the Council of Labour and Defence, he was on the Central Committee and Politburo of the Communist Party.The only individual to have anywhere near this influence was Lenin's right-hand man, Yakov Sverdlov, who died in March 1919 during a flu pandemic.
