The EKA defines itself as a federation of the Carlist parties of each of the four Basque provinces (Navarre, Álava, Gipuzkoa and Biscay), each of them fully autonomous in their respective territories.

After the general assembly of October 2008, the party appointed José Maria Porro Saínz (ex-militant of the Grupos de Acción Carlista and one of the leaders of Unión Sindical Obrera in Navarre) as its secretary general and Feliciano Vélez (who after the municipal elections of 2007, was elected mayor of the Navarrese town of Puente la Reina in the lists of the Agrupación Electoral Puentesina) as organization secretary.

Ideologically, the party defends a model of socialism based in workers' self-management and a federal Euskal Herria in a confederal Spain.

[4] In smaller rural towns, the party always supported or created diverse local platforms, like Agrupación Electoral Puentesina in Puente la Reina (Navarre).

In the local elections of 2003, the following Navarrese carlists were elected as councilors: Gerardo Montoya (Noain), Feliciano Vélez and Aurelio Laita (Puente La Reina – Gares), J. Joaquín Urra (Artajona - Artaxoa), Federico Salcedo (Andosilla), Cruz Barandalla and Roberto Beruete (Zirauki) and Carlos García (Tabar).
