 In the early 1990s and later on, Kirill was accused of having links to the KGB during much of the Soviet period, as were many members of the Russian Orthodox Church hierarchy, and of pursuing the state's interests before those of the Church.His alleged KGB agent's codename was "Mikhailov".These dissident ex-UGCC clergy called a (Soviet-supervised) "synod" (Lviv Sobor of 1946) in Lviv and at this synod annulled the Union of Brest of 1596 and all of its statutes.
