Alter leaving the LSE in 1943, MacKenzie spent the next 19 years until 1962 as an assistant editor with the
New Statesman magazine, specialising in sociology and communism. MacKenzie made frequent trips behind the
Iron Curtain throughout the 1950s and possibly worked for
MI6 gathering intelligence. On a visit to Bulgaria in 1955 he got a tip-off that Soviet premier
Nikita Khrushchev was going to denounce
Stalin but his report was not believed until the
speech was actually given some months later, in February 1956. He was twice unsuccessful at elections as the Labour candidate for
Hemel Hempstead in 1951 and 1955. In 1957 he was involved in the formation of the
Campaign for Nuclear Disarmament (CND). ==Orwell's list==
