Ricardo Froilán Lagos Escobar is a Chilean lawyer, economist and social-democratic politician who served as president of Chile from 2000 to 2006. During the 1980s he was a well-known opponent of the Chilean military dictatorship and astounded contemporaries in 1988 by openly denouncing dictator Augusto Pinochet on live television. He served as Minister of Education from 1990 to 1992 and Minister of Public Works from 1994 to 1998 under President Eduardo Frei Ruiz-Tagle before narrowly winning the 1999–2000 presidential election in a runoff against Independent Democrat Union (UDI) candidate Joaquín Lavín. Lagos was the third president from the centre-left Coalition of Parties for Democracy to have governed Chile since 1990. He was succeeded on 11 March 2006 by Socialist Michelle Bachelet, from the same coalition. From 2007 to 2010 he served as a Special Envoy on Climate Change for the United Nations Secretary-General Ban Ki-moon. Lagos made an unsuccessful bid to run for president in the 2017 Chilean general election.
