Question: As early as what year was a spy ring set up in the Yugoslav party?
Sentence: Tito's leading role in liberating Yugoslavia not only greatly strengthened his position in his party and among the Yugoslav people, but also caused him to be more insistent that Yugoslavia had more room to follow its own interests than other Bloc leaders who had more reasons (and pressures) to recognize Soviet efforts in helping them liberate their own countries from Axis control.
Answer in sentence: no
