Georgi Ivanov Markov was a Bulgarian dissident writer. He worked as a novelist, screenwriter and playwright in his native country, the People's Republic of Bulgaria, until his defection in 1969. After relocating to London, he worked as a broadcaster and journalist for the BBC World Service, the Radio Free Europe and West Germany's Deutsche Welle. Markov used such forums to conduct a campaign of sarcastic criticism against the incumbent Bulgarian-Soviet regime.
