Tuesday's Documentary
Few initials in modern times have more sinister or frightening connotations than those three letters: KGB. For the KGB is not just the Soviet intelligence service, it is a vast secret police apparatus penetrating every aspect of everyday life in Russia.
One of the most important KGB officers ever to defect to the West, Yuri Ivanovitch Nosenko , recently agreed to be interviewed for the first time on television, for this new and completely updated version of the programme originally shown on BBC2. Before he left Russia, Nosenko was deputy head of the department concerned with the surveillance of tourists in Moscow. What operations does the KGB mount against foreigners who visit Russia? How much is the ordinary tourist watched?
Another ex-KGB officer, Nikolai Khokhlov , talks about what it feels like to work for the organisation. Others with first-hand experience of the KGB describe some of the methods it uses. Narrated and produced by MISCHA SCORER
Script consultants EDWARD CRANKSHAW and PETER REDDAWAY
