Stig Svante Eugén Bergling, later Stig Svante Eugén Sandberg and Stig Svante Eugén Sydholt, (1 March 1937 – 24 January 2015) was a Swedish Security Service officer who spied for the Soviet Union. The Stig Bergling-affair, one of Sweden's greatest spy scandals, began when he was arrested in Israel in 1979 by Israeli counterintelligence and in the same year in Sweden was sentenced to life imprisonment for aggravated espionage. He fled to Moscow, however, during a conjugal visit in 1987. Bergling's escape was a major embarrassment for Sweden's liberal prison system and prompted the resignation of the justice minister.
