Mitrokhin Archive reaches Britain

1992Contested

In 1992 Vasili Mitrokhin, a retired KGB archivist, defected to Britain with thousands of pages of notes he had secretly copied from the KGB's foreign intelligence files. Published from 1999, they exposed Soviet spies and operations around the world.

The story

Vasili Mitrokhin was an archivist in the KGB's First Chief Directorate, its foreign intelligence arm. From 1972 he supervised the transfer of its files to a new headquarters at Yasenevo outside Moscow, and over twelve years he copied extracts by hand, smuggling the notes home in his shoes and clothing and hiding them under his dacha floor. In 1992, after the Soviet Union collapsed, he walked into the British embassy in Vilnius, Lithuania, with samples. Britain's intelligence service MI6 brought him, his family and his trunks of notes to Britain later that year.

The material led to investigations in many countries. In 1999 Mitrokhin and the Cambridge historian Christopher Andrew published the first volume of The Mitrokhin Archive, which revealed among other things that Melita Norwood, an 87-year-old great-grandmother in Britain, had spied for Moscow for decades. A second volume in 2005 covered the KGB in Asia, Africa and Latin America and caused political storms in India and Italy. Mitrokhin died in 2004, and his papers were opened to the public at Cambridge's Churchill Archives Centre in 2014.

Why it mattered

  • The archive is one of the largest sources on Soviet foreign intelligence ever made public, used by historians of the Cold War worldwide.
  • Its revelations triggered spy investigations and political rows in Britain, Italy, India and elsewhere.
  • The public opening of the papers in 2014 let researchers check claims that had rested on the published books.

Contested history

Consensus: KGB archivist Vasili Mitrokhin secretly copied foreign intelligence files for twelve years and defected to Britain in 1992. His notes, published from 1999 and opened in 2014, are accepted by historians as genuine KGB material, though specific claims drawn from them have been disputed.

Mitrokhin's notes are genuine extracts from KGB filesEstablished
Western intelligence services verified many leads, investigations confirmed spies such as Melita Norwood, and historians treat the archive as authentic, while noting the notes are copies, not original documents.

The archive shows the KGB funded and influenced politicians in IndiaDebated
The second volume described KGB payments and press operations in India in the 1970s. Indian politicians rejected the claims, and critics note they rest on KGB officers' own reports, which may exaggerate their success.

Italy's government covered up the names in the archiveDebated
An Italian parliamentary commission from 2002 to 2006 investigated why the files were not acted on sooner, but it split along party lines, and its findings are widely seen as politicized.
