Plurinational Legislative Assembly

The 2010–2015 Plurinational Legislative Assembly were controlled in both houses by the governing Movement for Socialism (MAS-IPSP), elected with a 2/3 supermajority. Just four incumbent members of the 2005–2010 Congress returned: Deputy Antonio Franco; Deputy Javier Zabaleta (MAS-IPSP/MSM); Senator René Martínez (MAS-IPSP), who was a deputy; and Senator Róger Pinto, previously of Podemos and now representing PPB-CN.[2] As part of a break between the MAS-IPSP and its ally the Without Fear Movement (MSM), the latter party's four deputies, elected on the MAS slate pledged in late March 2010, "to act in accord with our political identity, with our conscience, and with the people who elected us with their vote." Consequently, MAS-IPSP now has 84 members in the Chambers of Deputies, while the MSM has four.[3]

Government Palace of Bolivia in downtown La Paz.

The two chambers of Congress meet in the legislative palace located on Plaza Murillo, La Paz's main city-centre square. Plaza Murillo is also flanked by the presidential palace (informally known as the Palacio Quemado – the "Burnt Palace" – on account of repeated attempts to raze it to the ground in the 19th century) and the cathedral of Nuestra Señora de La Paz. Prior to becoming the seat of the legislature in 1904, the congress building had, at different times, housed a convent and a university.

The Vice-President, in his capacity as President of Congress, has an imposing suite of offices on Calle Mercado in central La Paz. The building, designed by Emilio Villanueva, was erected during the 1920s and was originally intended to serve as the headquarters of Bolivia's central bank (Banco de la Nación Boliviana). Under Jaime Paz Zamora's 1989–1993 presidency, the building was reassigned to the vice-presidency, but the vice-presidential staff did not relocate entirely until major reconstruction and renovation work, starting in 1997, had been carried out. The Library of Congress and the National Congressional Archive are also located on the premises.
