Results

About the election: President Enrique Peña Nieto's Institutional Revolutionary Party (PRI) secured a majority, in coalition with the Green Party of Mexico (PVEM) and the New Alliance. The coalition won 260 seats in the 500-member Chamber of Deputies. Traditional parties saw a reduction in their share of seats. The National Action Party (PAN) took 108 seats - their worst result since 1994. The Democratic Revolutionary Party (PRD) also won fewer seats (60). Thirty-five seats were taken by the National Regeneration Movement (MORENA), a PRD splinter group, headed by former PRD leader Andrés Manuel López Obrador.

These elections were the first to be held after the 2014 constitutional amendments came into force. The amendments allow parliamentarians to seek election for consecutive terms totalling 12 years: up to four consecutive three-year terms for the members of the Chamber of Deputies and two consecutive six-year terms for Senators. Candidates seeking re-election under the revised law are obliged to run for the same party or coalition. The amendments also allow independent candidates to run in elections and require that women should make up 50% of the nominees for all parties in legislative races. In all, 211 women were elected in 2015, up from 184 at the previous elections in 2012.

During the election campaign, the major parties focused discussions on anti-corruption measures, security issues and social and economic development. One of the country's main teaching unions held protests against the 2013 education reform, which provides for teachers to be evaluated. Although the President announced the suspension of the education reform a week before polling day, the union called for an election boycott and prevented 400 voting centres from opening. The union also campaigned for the safe return of some 40 college students, who disappeared in September 2014: prosecutors say that a drug gang killed the students and burned their bodies.
