2016 disestablishments in Navarre

Cambio-Aldaketa () was a grouping of electors in Navarre supported by the "quadripartite", the political parties supporting Uxue Barkos's regional government—Geroa Bai, EH Bildu, Podemos and Izquierda-Ezkerra—to contest the 2015 Spanish Senate election. The first incarnation of the alliance was disbanded after it secured only one out of the four directly-elected senators in Navarre, with its stated aim having been to win the election and subsequently obtain three senators.
