Elected Congress members Carlos Torres Caro, Gustavo Espinoza and Rocío González left UPP after the defeat of the party's presidential ticket, led by Ollanta Humala and featuring Torres Caro as a candidate to Second Vice-President, in the Second Round (runoff) of the 2006 national election. The rift arose when Humala called on radical left groups to join a "People's Democratic and Nationalist Front" ("Frente Nacionalista Democrático y Popular"), to be led by UPP and Humala's own Peruvian Nationalist Party.
