Antonio Guterres

Guterres became Prime Minister of Portugal on October 28, 1995, after his Socialist Party won the general election. He led a center-left government focused on economic growth and social welfare.

Guterres oversaw the successful hosting of Expo 98 in Lisbon, a world's fair themed around the oceans. The event revitalized the city's eastern waterfront and boosted Portugal's international image.

Guterres resigned as Prime Minister on December 17, 2002, after his party suffered heavy losses in local elections. His government had faced economic slowdown and criticism over handling of the economy.

Guterres became the ninth UN Secretary-General on January 1, 2017, succeeding Ban Ki-moon. He prioritized climate action, conflict resolution, and reform of the UN system, including addressing the Rohingya crisis and Syrian civil war.
