Kim Philby

Cambridge and recruitment

According to media and secondary accounts · not confirmed by official sourcesHe was born on 1 January 1912 in Ambala, India. He became a communist while at Cambridge; according to Encyclopaedia Britannica, he began working for Soviet intelligence in 1933.³

MI5 files released at The National Archives in January 2025 confirm that he, Guy Burgess, Donald Maclean, Anthony Blunt and John Cairncross were recruited by Soviet intelligence in the 1930s. According to those files, Philby himself said in Beirut that he had spied for the Soviet Union from 1934 to 1946.¹

In British intelligence

According to media and secondary accounts · not confirmed by official sourcesAccording to Britannica, Burgess brought him into SIS in 1940. By the end of the war he was running counter-espionage operations there, and in 1949 he went to Washington as SIS’s chief representative and liaison with US intelligence.³

In 1951 he warned Donald Maclean, through Burgess, that the security services were about to take action against him. In July 1951 he was asked to resign from the Foreign Service, and did so – as the government put it to the House of Commons in 1963.²

Suspicion and clearance

After Burgess and Maclean disappeared in 1951, MI5 gave him the codename PEACH. He was summoned home from Washington for interviews with Dick White (file KV 2/4723), and on 12 December 1951 he was questioned by Helenus Milmo; the transcript runs to 89 pages (KV 2/4727).¹

On 7 November 1955 the Foreign Secretary, Harold Macmillan, told the House of Commons that no evidence had been found that Philby had warned Burgess or Maclean, and that there was no reason to identify him with the so-called third man.⁴

He later worked in Beirut as the correspondent of a British newspaper.²

Confession and flight

In 1962 proof emerged that he was a Soviet agent. In January 1963 an SIS officer confronted him in Beirut. The officer’s name is redacted in the files; he is commonly believed to have been Philby’s old friend Nicholas Elliott. The partial confession, dated 11 January 1963, covers the years 1932 to 1940 (KV 2/4737).¹

On 1 July 1963 Edward Heath told the House of Commons that, partly as a result of an admission by Philby himself, the security services had established that he had worked for the Soviet authorities before 1946. He added that after leaving Beirut Philby might have gone to one of the countries of the Soviet bloc.²

According to media and secondary accounts · not confirmed by official sourcesAccording to Britannica, he settled in the Soviet Union, rose to the rank of colonel in the KGB and died in Moscow on 11 May 1988.³
