Lazar Kaganovich
Oppositionists Christian Rakovsky and Lev Kamenev held brief speeches in front of the Congress. Rakovsky's speech was interrupted fifty-seven times by his opponents, including Nikolai Bukharin, Martemyan Ryutin, and Lazar Kaganovich. Although, unlike Rakovsky, Kamenev used the occasion to appeal for reconciliation, he was nevertheless interrupted twenty-four times by the same group.
