Elizabeth Duval announced her resignation from the leadership of Sumar on Friday, March 21, 2025, just days before the party's upcoming congress scheduled for March 29-30. As the Secretary of Communication and one of four interim coordinators following the resignation of Yolanda Díaz, Duval stated in a social media message, "After deep reflection, I have decided not to present myself on the lists and to close my stage in the leadership bodies of Sumar." Her departure marks a significant moment for Sumar, which she noted is about to enter a new phase, turning a page on the initial hypothesis under which the project was founded.

Duval has previously expressed her determination to remain independent, aiming to represent a coalition of progressive forces rather than a single party.

Duval, recognized as a writer and an activist for trans rights, was a key figure brought into Sumar by Yolanda Díaz ahead of the July 2023 general elections.

She served as the spokesperson for feminisms, gaining substantial visibility within the campaign led by Díaz, who then became the party’s general coordinator.

Her term in leadership coincided with a challenging period for Sumar, which faced a series of electoral defeats across various regions, including Galicia, the Basque Country, and Catalonia, leading to the resignation of Díaz amid party tensions.

Sumar has since been guided by a collegiate coordination model consisting of Duval, Lara Hernández, Rosa Martínez, and Txema Guijarro.

As Sumar heads towards its congress, which will address new leadership structures, Duval's resignation adds to an atmosphere of uncertainty regarding the future of the coalition, especially in the context of upcoming electoral alliances.

The party has been quiet for over a week about who will compete for the general coordinator position, with the candidate submission window closing on March 9.

Yolanda Díaz expressed gratitude towards Duval for her contributions and emphasized their shared commitment to fighting for social justice and rights.

Sources within Sumar described Duval’s decision as personal, reaffirming their respect for her choice.

In her resignation announcement, Duval remarked on the ongoing challenges that lie ahead and noted, "The struggle for social justice, rights, and democracy does not begin and end in institutions or parties." She aims to continue contributing from different fronts, wishing her colleagues in Sumar the best as they pursue their shared goals.

Duval’s exit follows other recent departures within the party leadership, signaling a period of transformation as Sumar navigates its future direction amidst a reconfiguration of the left-leaning political landscape in Spain.
