The Senate of the Republic, (Spanish: Senado de la República) constitutionally Chamber of Senators of the Honorable Congress of the Union (Spanish: Cámara de Senadores del H. Congreso de la Unión), is the upper house of Mexico's bicameral Congress. It currently consists of 128 members, who serve six-year terms.

Make-up

After a series of reforms during the 1990s, the Senate is made up of 128 senators:

• Two for each of the 32 states elected under the principle of relative majority;
• One for each of the 32 states assigned under the principle of first minority (i.e. awarded to the party who had won the second highest number of votes within the state or Federal District);
• Thirty-two national senators-at-large, divided among the parties in proportion to their share of the national vote.
