In 1927, the United Opposition (Trotsky, Zinoviev, Kamenev, etc.), looking for ways to print their platform illegally, came into contact with a man who was actually a GPU provocateur.This person had been an officer in the counterrevolutionary Wrangel Army several years earlier. The Stalin faction denounced the opposition's “association with a white officer”. In fact, the opposition briefly had contact to a man whose background they did not know, while Stalin's secret service employed this man for years, knowing his background very well, which showed the hypocrisy of their denounciations.
