Secret surveillance of Britain’s notorious double agent, Kim Philby, made public for the first time in archived documents, reveals how keenly the Security Service wanted to confirm or disprove early suspicions of his high-level treachery.
In daily bulletins submitted to MI5 in November 1951, undercover operatives describe how Philby, codenamed Peach, moved about London.
They said he gave “no outward sign of being either nervous or on the alert, but your well trained man should not do so; every movement is natural – again as it should be”.
