Reyes Maroto and Enma López both clear 823-signature hurdle, setting up July 19 PSOE primary for Madrid mayor

The endorsement race

On Saturday at noon, the deadline closed for collecting the 823 membership endorsements required to stand. Both candidates delivered boxes of physical signatures to the party's regional headquarters at Calle Buen Suceso. The final tally is still being compiled, but the regional branch confirmed both had surpassed the minimum. Online endorsements showed 587 for López and 186 for Maroto. Maroto stated on social media she had obtained more than 1,400 total endorsements, while López told reporters her rough count was around 1,000.

Today we don't just bring endorsements, we also bring the trust and the enthusiasm of hundreds of members who are committed to change in Madrid.

Two weeks that changed the race

López, the deputy spokesperson in the city council, announced her candidacy on 26 June, a move that caught the federal leadership off guard and generated what multiple sources described as significant discomfort. She resigned the same day from her role as secretary for Studies and Programmes on the party's federal executive committee, where she had served since December 2025 under Pedro Sánchez. In a letter posted on social media, she framed the resignation as an act of loyalty to the party and its leader. For the preceding two weeks, Maroto, a former minister and the current municipal group leader, had been the sole candidate and the only name backed by Ferraz, the party headquarters.

We have brought together a gigantic wave of enthusiasm that I am sure will carry us to Cibeles.

Ferraz's line vs the rank and file

The internal contest has exposed a rift. Maroto carries the weight of the party apparatus: most insiders never doubted she would reach the threshold. López, described by several figures in the articles as a free spirit, mobilised a digital-first campaign that one source characterised as awakening "a sleeping militancy," drawing in younger members and older ones who had grown disenchanted. Others argued her support base is confined to a permanent protest vote with limited reach. The party membership in the city stands at approximately 5,400 people.

What happens next

The election calendar allows a one-week information campaign running from Sunday 12 July to Saturday 18 July. Polling on 19 July will remain open from 10:00 to 20:00 without interruption. To win outright in the first round, a candidate must exceed 50 percent of valid votes cast. If neither reaches that threshold, a second round will be held one week later, on 26 July, with the winner determined by simple majority.

The wider 2027 landscape

Whoever secures the nomination will face José Luis Martínez-Almeida of the conservative PP, who has already confirmed he will seek a third term as mayor. On the left, Más Madrid's Rita Maestre secured her party's candidacy with 81.2% of the vote in her own primary. Elsewhere in Madrid politics, the parallel race for the PSOE candidacy to the regional presidency was settled on Saturday without a contest: minister Óscar López became the automatic nominee after his only rival, Silvia López Quivira, a grassroots member with little profile, failed to collect the required endorsements. Óscar López reportedly gathered more than 2,092 signatures, the maximum allowed, which is 15% of the regional census.
