Prime minister of Portugal in the context of "Pedro Santana Lopes"

António Manuel de Oliveira Guterres (born 30 April 1949) is a Portuguese politician and diplomat who has served as the ninth secretary-general of the United Nations since 2017. A member of the Portuguese Socialist Party, Guterres served as the prime minister of Portugal from 1995 to 2002.

Born in Cascais, Guterres studied physics and electrical engineering at Lisbon's Instituto Superior Técnico, briefly taught systems theory and telecommunications, and became involved in politics while active in a Catholic youth group. Guterres served as secretary-general of the Socialist Party from 1992 to 2002. He was elected prime minister in 1995. He led the party to legislative victories in 1995 and 1999. Guterres announced his resignation as Socialist Party leader in 2002 following the party's losses in the 2001 local elections, with Eduardo Ferro Rodrigues succeeding him while he remained prime minister until losing the subsequent general election to José Manuel Barroso's Social Democratic Party. Despite this defeat, polling of the Portuguese public in both 2012 and 2014 ranked Guterres the best prime minister of the previous 30 years.
