LONDON (Reuters) - Vadim Bakatin, a liberal politician who briefly headed the Soviet KGB in the months leading up to the collapse of the USSR, has died at the age of 84, Russian state media said on Monday.

Bakatin was appointed by Soviet leader Mikhail Gorbachev to head the security service after its previous boss, Vladimir Kryuchkov, played a leading role in a failed coup against Gorbachev in August 1991.
