12th Federal Assembly of United Left (Spain)

The 12th Federal Assembly of United Left was held in Madrid from 26 March to 27 March 2021, to renovate the governing bodies of the United Left (IU) and establish the party's main lines of action and strategy for the next leadership term. The federal assembly was initially scheduled for July 2020, but it was postponed as a result of COVID-19 pandemic.

The congress was held following the November 2019 Spanish general election when the alliance managed to enter the government for the first time since the Second Republic. The incumbent general coordinator and Minister of Consumer Affairs Alberto Garzón was reelected for a second term with 76.3% of the vote, thus defeating the candidacy of José Antonio García Rubio; who was supported by former leading figures of IU against the alliance with Podemos and got 20.8% of the vote.

The approved political document called for a bigger integration of IU within the Unidas Podemos alliance, eventually leading to an organizational convergence with Podemos. However, these plans were halted by the establishment of the Sumar platform led by Yolanda Díaz, former member of IU, ahead of the 2023 Spanish general election.
