Britain's Soviet spy scandal - a podcast by BBC World Service

In 1971 during the Cold War, the UK expelled 90 Soviet diplomats suspected of spying. They'd been allowed into Britain in an attempt to improve relations, but it was later discovered that they'd been carrying out espionage instead. George Walden was a young diplomat working on the Soviet Desk in the Foreign Office at the time. He spoke to Dina Newman in 2018.
