The Guardian is well known for being of the left.
“In 1995, KGB defector Oleg Gordievsky identified prominent Guardian editor Richard Gott as one of his agents. While Gott denied that he received cash, he confessed taking benefits from the KGB on a visit to the Soviet Union.
Gordievsky commented on the newspaper: “The KGB loved The Guardian. It was deemed highly susceptible to penetration”.”
