Legislative elections were held in Mexico on 6 July 1997.^[1] The Institutional Revolutionary Party won 239 of the 500 seats in the Chamber of Deputies, the first time it had failed to win a majority. As a result, the leaders of the Party of the Democratic Revolution and of the National Action Party were able to control Congress and installed PRD member Porfirio Muñoz Ledo as the president of the Chamber of Deputies. At first, the PRI refused to accept the nomination and its parliamentary leader, Arturo Núñez Jiménez, declared it illegal. However, the PRI later accepted the fact and Muñoz Ledo answered the state of the union address of President Ernesto Zedillo.

The Party of the Cardenist Front of National Reconstruction (PFCRN), Popular Socialist Party (PSP) and Mexican Democratic Party (PDM) all lost their legal registration and disappeared, while the Labor Party (PT) and the Ecologist Green Party of Mexico (PVEM) consolidated their support, which turned them into parties who could form coalition governments. Voter turnout was between 57% and 58%.^[2]
