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.
