In 1936, Kamenev and Zinoviev both confessed to being involved in Trotskyite plots to overthrow Stalin and the murder of Kirov.
They were both shot after the trial.
In the 1937, leading figures of the Communist Party in Piatakov, Radek and Sokolnikov had questioned Stalin's policies especially after industrialisation.
This show trial demonstrated that no one was safe.
After being tortured in the infamous Lubianka prison, they all confessed to forming an "Anti-Soviet Trotskyist Centre" and were shot.
The show trial of Bukharin, Rykov and Yagoda in 1938 was the last and most famous of the show trials.
Bukharin confessed to involvement in plots against Stalin and was shot.
Yagoda was arrested in 1936 and after the torture, he confessed to a startling array of crimes such as the murder of Kirov, the novelist Gorky and the NKVD Head before him.
Yagoda also confessed to corruption through diamond dealing, being a German spy and attempting to murder Yezhov.
Yagoda was shot along with his father-in-law and brother-in-law and his sister and parents were exiled.
