Un Paso al Frente () is a proposed electoral alliance established ahead of the next Spanish general election, to be formed by United Left (IU), Unite Movement (MS), Más Madrid and Catalonia in Common (Comuns). The alliance was launched in a political event on 21 February 2026, attended by all Spanish government ministers of the Sumar platform (Ernest Urtasun, Mónica GarcÃÂa, Pablo Bustinduy and Sira Rego), except for the second deputy prime minister and labour minister, Yolanda DÃÂaz.
It aims to supersede the existing Sumar alliance, and is left open for other parties (such as Podemos) to join, though the latter rejected joining any such alliance. Other parties such as Coalició CompromÃÂs, Més per Mallorca and Chunta Aragonesista are expected to joint at some point. While DÃÂaz was considered by the founding parties as the alliance's candidate, she rejected it on 25 February 2026.
