The Cambridge Spies; The Prague Spring; KGB Defector Vasili Mitrokhin

From the BBC

"Members of the "Cambridge Five" spy ring were seen by their Soviet handlers as hopeless drunks incapable of keeping secrets, newly-released files suggest.

Donald Maclean, Guy Burgess, "Kim" Philby and Anthony Blunt were recruited as Soviet spies while at Cambridge University in the 1930s.

There may have been a fifth spy in the ring, possibly John Cairncross.

Documents from the Mitrokhin Archive have been made publicly available for the first time.

The FBI described them as the most complete intelligence ever received.

Major Vasili Mitrokhin smuggled the information out of Soviet archives during 12 years working for the KGB"

"On Monday, the Archive Centre at Churchill College, Cambridge made available to the public for the very first time the results of one of the biggest intelligence leaks in history. The documents, collected by Vasili Mitrokhin, a KGB defector, were handed over to the UK authorities in 1992 and include details on the Soviet agency’s infiltration efforts regarding the 1968 Czechoslovak Prague Spring. In total, 19 boxes of Mitrokhin’s notes will be made available, and could help Czech historians shed more light on a painful chapter in the country’s history".
