Basque-Catalan movement that seeks the recognition of protest votes in the form of empty seats in a legislative body. Party lobbies for an electoral law that would allow the voter to opt out of selecting any party formation on a ballot, save "Blank". Selecting this option should automatically translate into empty seats. Party is led by Mario Barcenilla Escaño [Escaños en Blanco (EB); Escons en Blanc (Catalan); Aulki Zuriak (Euskera)].
