Zinoviev and Kamenev remained politically inactive until October 1932, when they were expelled from the Communist Party, after receiving an oppositionist group's appeal but not informing the party on their activities during the Ryutin Affair. After again admitting their alleged errors, they were readmitted in December 1933. They were forced to make self-flagellating speeches at the 17th Party Congress in January 1934, where Stalin paraded his erstwhile political opponents, showing them to be defeated and outwardly contrite.
