In a 1992 interview for the programme "As It Happens", aired by Canada's CBC Radio, Blake praised the general concept of Communism. He said that he had offered his services to the Soviet Union because he viewed Communism as "a great experiment of mankind, to create a more just society, to create, in fact, the kingdom of God in this world". During this discussion, he denied responsibility for the deaths of any British agents, having been assured by the Soviets that none were executed based on the intelligence that he had provided, and stating that he believes they didn't lie. However, according to NPR, "Blake gave up the identities of hundreds of British spies, some of whom were executed."
