Spanish opposition figures question postal voting integrity ahead of 29 November election

Dispute over mail-in ballots

The announcement of snap general elections in Spain, scheduled for 29 November 2026, generated immediate confrontation over electoral procedures. Minutes after Prime Minister Pedro Sánchez called the vote on Monday, 5 October, Community of Madrid President Isabel Díaz Ayuso urged voters to avoid casting ballots by mail. Vox president Santiago Abascal backed the message during a press appearance at party headquarters, alleging potential manipulation by the central government.

I encourage you to vote at the ballot box and to vote safely.

Ayuso reaffirmed her position the following day, describing Sánchez as untrustworthy and insisting that voters should cast their ballots in person. Her statements follow previous remarks questioning electoral integrity, including during the May 2023 municipal elections after vote-buying investigations in Melilla and Mojácar.

Internal divisions in the Popular Party

The rhetoric created divergent responses within the leadership of the Popular Party (PP). Party president Alberto Núñez Feijóo, who previously served three years as president of state postal service Correos, did not issue a public statement regarding the fraud claims. PP national spokesperson Borja Sémper defended the voting framework during media interviews, calling the Spanish electoral process rigorous and urging citizens to trust the Central Electoral Board (JEC).

Let us trust the system and trust that the JEC, in which the PP is represented, will do its work and continue guaranteeing, as always, that the Spanish system is clean and offers full guarantees.

Other PP figures expressed skepticism toward Correos management rather than ordinary employees. Congressional spokesperson Ester Muñoz stated that while postal workers retain public trust, concerns exist regarding political appointments made by the Spanish Socialist Workers' Party (PSOE). Muñoz referenced former Correos president Juan Manuel Serrano, who faces judicial investigation by National Court Judge Santiago Pedraz in an ongoing probe into party activities. Regional leaders aligned with the critical stance, with Aragon President Jorge Azcón stating his children would vote in person, Melilla President Juan José Imbroda calling for precautions, and Basque PP President Javier de Andrés backing scrutiny.

Postal procedures and census oversight

State postal operator Correos opened the application window for mail-in voting on Tuesday, 6 October. Citizens registered in Spain can request postal voting materials online or in person at postal branches until 19 November, ten days before polling stations open on 29 November.

Former Correos employee of 25 years and former Jaén deputy Ildefonso Ruiz addressed the debate over system vulnerabilities. Ruiz explained that while direct tampering with submitted mail-in ballots is practically impossible, potential flaws involve control over electoral census rolls. He noted that access to voter lists, electoral wards, and turnout records managed through the National Statistics Institute (INE), INDRA, and Correos requires rigorous monitoring by party representatives.
