The headquarters of the Czechoslovak intelligence service regarded Portugal as a favourable territory for operations. The plan was for the Lisbon residentura to infiltrate and gather information about US, NATO and EEC facilities. Portugal's close ties to US industry were suitable for obtaining data, documents and materials in electronics, engineering and biotechnology. The residentura was established here in the late 1970s, after the Carnation Revolution. The Resident from 1981 – 1985 was First Lieutenant Miroslav Manďák "Roland". The last Resident was Captain JUDr. Oldřich Tobiáš "Trojan" in 1988.
