Both chambers of Congress were elected in the 2024 general election. There were three competing forces: the Sigamos Haciendo Historia coalition, consisting of the National Regeneration Movement (Morena), the Labor Party (PT), and the Ecologist Green Party of Mexico (PVEM); the Fuerza y Corazón por México coalition, comprising the National Action Party (PAN), the Institutional Revolutionary Party (PRI), and the Party of the Democratic Revolution (PRD); and the Citizens' Movement (MC), the only party to run without allies.
Sigamos Haciendo Historia won a supermajority in the Chamber of Deputies, granting the ruling coalition 73% of the seats, the highest share since the LII Legislature in 1982, during Miguel de la Madrid's presidency.[2] Although the coalition fell three seats short of a supermajority in the Senate, defections by two senators elected for the PRD on 28 August closed the gap to one.[3] The supermajority was ultimately secured with the defection to Morena of Cynthia López, elected for the PRI in Mexico City, on 12 November.[4] This marked the first time since the LIII Legislature in 1985 that the ruling coalition held a supermajority in both chambers.[5]

Leadership
Senate Board of Directors
The Senate's Board of Directors (Mesa Directiva) is composed of a president, three vice presidents and four secretaries, elected by an absolute majority of the senators present in a ballot vote and serving one legislative year, with re-election permitted. For the second and third years it is chosen at a preliminary meeting held in the ten days before sessions open.[24] The Senate has repeatedly gone beyond that statutory minimum, adding posts by parliamentary agreement so that every parliamentary group is represented: a fourth vice presidency and three further secretaryships in September 2024, and eight secretaries in 2025–2026.
2024–2025
The Senate elected its first Board of Directors on 29 August 2024, choosing Gerardo Fernández Noroña (Morena) as president in a ballot vote with 127 votes in favor and one against.[25] On 3 September, the Senate approved an agreement of its Political Coordination Board adding, for that legislative year, a fourth vice presidency for the PVEM and three further secretaryships, allotted to Morena, the PAN and the PRI.[26]

2025–2026
At the preliminary meeting of 29 August 2025, the Senate elected Laura Itzel Castillo (Morena) as president by secret ballot, approving the slate with 101 of the 106 votes cast, the remaining five going to other candidates.[27] It was the first time in 96 years that the PRI held neither the presidency nor a vice presidency of the board,[28] a consequence of Senator Néstor Camarillo leaving the party for Citizens' Movement (MC) two days earlier, which reduced the PRI to thirteen senators and fourth place in the chamber.[29] The board comprised eight secretaryships, one for each parliamentary group and three for Morena.[30] Secretary Gustavo Sánchez Vásquez (PAN) died in office on 31 January 2026 and was replaced on 24 February by Gina Gerardina Campuzano González.[31]

Chamber of Deputies Board of Directors
The Board of Directors (Mesa Directiva) is elected by the plenary and consists of a president, three vice presidencies and one secretaryship proposed by each parliamentary group; its members serve one year and may be re-elected.[35] For the second and third years of a legislature the law requires the presidency to pass, in decreasing order, to the largest parliamentary groups that have not yet held it, and bars it from the group presiding the Political Coordination Board; it accordingly went from Morena to the PAN and then to the PVEM.[35]
2024–2025
The Chamber elected its first Board of Directors at the constitutive session of 29 August 2024, choosing Ifigenia Martínez y Hernández (Morena) as president with 496 votes.[36] Martínez y Hernández died in office on 5 October 2024; three days later the Chamber designated, by a unanimous 420 votes, First Vice President Sergio Gutiérrez Luna as substitute president, Dolores Padierna Luna as vice president and José Luis Montalvo Luna as secretary in place of Pedro Vázquez González, all three taking office the same day.[37] Third Vice President María del Carmen Pinete Vargas died on 1 April 2025; María Luisa Mendoza Mondragón was elected with 394 votes on 22 April to complete the term.
