Miguel Ángel Mancera

Miguel Ángel Mancera Espinosa (Spanish: [miˌɣeˈlaŋxel manˈseɾa]; born 16 January 1966) is a Mexican lawyer and politician who has represented the Party of the Democratic Revolution (PRD). He served as the head of government of Mexico City from 2012 to 2018.

Mancera earned his law degree from the Faculty of Law at the National Autonomous University of Mexico (UNAM) in 1989 and received the Gabino Barreda Medal in 1991 for academic excellence. He holds a master's degree from both the University of Barcelona and the Metropolitan Autonomous University, as well as a Juris Doctor from UNAM. Mancera has taught at several universities, including the UNAM, the Autonomous Technological Institute of Mexico and the University of the Valley of Mexico.

In 2002, he began working in public service when Marcelo Ebrard, then Secretary of Public Security of Mexico City, invited him to serve as an adviser. In 2006, Mancera was appointed Assistant Attorney General, and from 2008 to 2012, he served as the city's Attorney General. In early 2012, Mancera was selected as the candidate for Head of Government of the Federal District by the Progressive Movement coalition, which included the PRD, the Labor Party, and the Citizens' Movement. In the election held on 1 July 2012, he won with over 66 percent of the vote.

He took office on 5 December 2012. During his mandate, Mancera faced the increase of the Mexico City Metro fare, the first closure of Metro Line 12 due to construction issues, the introduction of the city's constitution, the implementation of new driving regulations, and the 2017 Puebla earthquake. He resigned on 29 March 2018, to run for the Senate, leaving office with the lowest approval rating for a head of government. His administration was scrutinized by his successor, Claudia Sheinbaum, who prosecuted multiple crimes allegedly committed during his tenure. Ultimately, Mancera was sanctioned with a one-year disqualification from holding any public office in the city after promoting a presidential candidate while serving as head of government. He served as proportional-representation senator from 2018 to 2024.
