António Guterres [SEP] Introduction
António Manuel de Oliveira Guterres (; ; born 30 April 1949) is a Portuguese politician and diplomat serving as the ninth secretary-general of the United Nations. A member of the Portuguese Socialist Party, he served as prime minister of Portugal from 1995 to 2002. Guterres served as secretary-general of the Socialist Party from 1992 to 2002. He was elected prime minister of Portugal in 1995 and resigned in 2002 after the Socialist Party was defeated in the 2001 Portuguese local elections. After six years governing without an absolute majority and with a bad economy, the Socialist Party did worse than expected because of losses in Lisbon and Porto, where polls showed it with a solid lead.
