Sumar Movement

An electoral platform established ahead of the 2023 Spanish general election, founded by Spanish second deputy prime minister and labour minister Yolanda Díaz, provisionally registered as an association on 28 March 2022 and publicly unveiled on 18 May. After a series of nationwide public events from July 2022 to 25 March 2023, the association launched its manifesto and officially announced Díaz's candidacy for the election on 2 April. On 30 May 2023, the association registered as a political party under the name Movimiento Sumar (Unite Movement), and then was registered as an electoral alliance joined by other parties (such as United Left, Más Madrid, Coalició Compromís, Catalunya en Comú and, temporarily, Podemos).

General Coordinator: Yolanda Díaz (until 10 June 2024), Interim collective coordination (10 June 2024 – 11 July 2026), Verónica Martínez Barbero and Rosa Martínez (since 11 July 2026).
