Navarrese People's Union
Since 2011 IUN-NEB has a permanent alliance with Batzarre, Izquierda-Ezkerra (I-E). After the 2015 Navarrese regional election I-E signed a pact with Geroa Bai, EH Bildu and Podemos to remove the Navarrese People's Union (UPN) from power and elect Uxue Barkos as the president of Navarre.
