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. 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.
