Confession of British spy for the Soviets made public for first time

Double agent Kim Philby's confession partially released to National Archives

Extracts from Kim Philby's official confession to the UK's security services in which he likens joining the Soviet secret police to signing up to the army, have been made public for the first time.

Philby, one of the Soviet Union's most notorious British cold war spies, fled to Moscow shortly after his 1963 admission of guilt.
