The Spanish Socialist Workers’ Party (PSOE) and the coalition Frente Amplio registered a joint list for the Spanish Senate elections shortly before the deadline on 16 October 2026. The list is standing under the name “Senado de Progreso” and, according to party leaders, applies nationwide except in the constituencies in Catalonia and the Canary Islands; La Gomera was included as an exception.
According to official announcements, the joint candidacy includes, alongside the PSOE, various left-wing parties and regional coalitions, including Izquierda Unida, Movimiento Sumar, Más Madrid as well as regional groups such as Més in the Balearic Islands and the platform Ceuta Ya in Ceuta. The signatories describe the agreement as “historic”, aimed at pooling centre-left votes in the Senate election and thereby improving the chances of success against the Partido Popular and the party Vox .
The background is the Partido Popular’s current majority in the Senate, resulting from the 2023 elections. The initiators of the joint list argue that the majoritarian electoral system in many provinces favours tactical alliances and that a unified list could reduce the splitting of left-wing votes. Electoral experts also warn that regional differences, local vote distribution and turnout on 29 November 2026 will be crucial to the result.
Catalonia and the Canary Islands have distinct political arrangements, so no single, identical nationwide list is standing there; the inclusion rule for La Gomera was negotiated locally. Whether the joint list “Senado de Progreso” will be enough to deprive the Partido Popular of an absolute majority in the Cámara Alta can only be assessed with certainty once all votes have been counted. Until then, the alliance’s impact remains a question of regional dynamics and voter mobilisation.
The move was officially registered within the statutory deadline; the parties involved now expect the electoral commission of the Junta Electoral to confirm the registrations.
