who was the double agent in tinker tailor soldier spy
Tinker Tailor Soldier Spy (film) Smiley learns that Alleline, Haydon, Bland and Esterhase have been meeting Polyakov—the "Witchcraft" source—at a safe house somewhere in London, where Polyakov gives them supposedly high-grade Soviet intelligence, in exchange for low-grade British material to help him maintain his cover with the Soviets. However, the mole is passing substantive material, including US intelligence, to Polyakov, his handler, whilst Polyakov's material has just enough substance to persuade the CIA to share information with the British. Smiley blackmails the location of the safe house out of Esterhase, whose exile status makes him vulnerable to deportation. Smiley then has Tarr appear at the Paris office, implying he knows who the mole is. The mole is revealed to be Haydon when he meets Polyakov at the safe house, where Smiley captures him. The Circus plans to exchange Haydon with the Soviets but he is killed by Prideaux. Smiley returns to the Circus as its new chief.
