If "Intelligentsia" was, indeed, Ivor Montagu, his rather haphazard informing had little of the impact of those much more famous Cambridge-educated spies, recruited as idealistic anti-Fascists in the 1930s, who continued to work at the height of the Cold War - Kim Philby, Guy Burgess and Donald MacLean. In 1952, MI5 intercepted a telegram from Ivor Montagu telling Charlie Chaplin how sorry he was to miss him in London when the star visited England that year; the British agency had agreed to spy on Charlie Chaplin for the FBI, who were looking for ways to keep him out of America at the height of McCarthyism. Apart from that, they left Montagu and his ping pong tournaments alone.
