Luis Carrero Blanco

Admiral-General Luis Carrero Blanco (Spanish pronunciation: [ˈlwis kaˈreɾo ˈβlaŋko]; 4 March 1904 – 20 December 1973) was a Spanish Navy officer and politician. A long-time confidant and right-hand man of dictator Francisco Franco, Carrero served as Prime Minister of Spain. Upon graduating from the naval academy Carrero Blanco participated in the Rif War, and later the Spanish Civil War, in which he supported the Rebel faction. He became one of the most prominent figures in the Francoist dictatorship's power structure and held throughout his career a number of high-ranking offices such as those of Undersecretary of the Presidency from 1941 to 1967 and Franco's deputy from 1967 to 1973. He also was the main drafter behind the 1947 Law of Succession to the Headship of the State. Franco handpicked him as his successor in the role of head of government, with Carrero thereby taking office in June 1973.

Shortly after he became prime minister, Carrero Blanco was assassinated in Madrid in a streetside bombing on 20 December 1973 by the Basque nationalist group Euskadi Ta Askatasuna (ETA) while he was returning from Mass in his car.
