The Partido Popular (PP) leadership has decided not to challenge Spain’s electoral system in court, despite concerns about the expansion of citizenship among descendants of Spaniards exiled abroad. The party is monitoring a process projected to produce as many as 2.4 million potential new voters over five years, but has no legal or parliamentary action planned for now. That projection is not the number already registered to vote: court-related figures put the group of citizens naturalised through the disputed route and listed in the overseas electoral register at 163,020 as of 1 August 2026.
The nationality pathway is set out in the eighth additional provision of Law 20/2022, of 19 October, on Democratic Memory, often called the “grandchildren’s law.” It covers certain descendants of Spaniards exiled for political or ideological reasons, as well as those forced into exile by religious persecution or discrimination based on sexual orientation. It does not automatically grant citizenship to everyone with a Spanish ancestor. The current legal dispute concerns administrative guidance that treated departures during broad historical periods as presumptive evidence of exile, and whether that interpretation exceeded the law. The dispute is not a general revocation of nationality already granted.
The PP fears that questions about how eligibility was assessed could affect future elections, particularly because overseas electors are spread across Spain’s 52 provinces. For now, the party plans to appeal directly to these voters rather than adopt the accusations of electoral manipulation frequently voiced by Isabel Díaz Ayuso against Pedro Sánchez. The 2.4-million figure is a projection of potential future beneficiaries, not a count of people currently able to vote through the contested mechanism. The reported court-related total was 163,020 on 1 August and 168,896 by late August, after the relevant electoral-register closing date.
Party officials say they are monitoring the issue closely, including after regional elections in Extremadura, Aragón and Castilla y León and the May 17 vote in Andalucía. The article’s account says the PSOE performed strongly among overseas voters in contests where it lost heavily at domestic polling stations. The PP acknowledges that the left has historically held an advantage in the external vote, with Galicia a rare exception. Spain’s overseas register, the Censo Electoral de Residentes Ausentes (CERA), held 2,736,522 electors on 1 July 2026, 408,262 more than at the 2023 general election. That increase covers the register as a whole and cannot be attributed solely to people who obtained citizenship under the Democratic Memory Law.
The dispute has also reached the courts. Spain’s Supreme Court provisionally restricted the voting effects of a group of citizens naturalised under the law while it examines the administrative interpretation used in some applications. The measure affects voting eligibility in an election, not citizenship itself. The Defensor del Pueblo appealed the restriction to the Constitutional Court, arguing that it affects citizens whose nationality has already been granted. Vox and Iustitia Europa have supported challenges to the administrative presumption. The Basic Electoral Board was reported to have agreed to send voting materials to registered overseas electors. The Supreme Court proceedings required the government to provide a nominal list of 163,020 affected CERA electors by 15:00 on 28 October. The reported distinction was between cases with consular documentation of exile and those relying solely on the disputed general presumption.
The PP estimates that around 600,000 of the projected 2.4 million potential new voters could already vote if general elections were held today. Despite internal disagreements, with some party members believing Sánchez will do anything to retain power, the leadership is opting for caution. Unlike Vox, which has called for legal challenges, the PP intends to persuade these new citizens to support political change in Spain.
Figures from Spain’s National Statistics Institute (INE) show that Argentina alone has more than 509,000 Spaniards registered in CERA, with impressive numbers also in France and the United States. As more people become eligible, their votes could matter in smaller provinces, where narrow margins can determine a seat. Spain’s overseas voting rules also changed in 2022, when the “voto rogado” requirement was removed. Under that rule, many overseas voters had to request a ballot. The register’s size is distinct from actual turnout, while valid ballots and seat allocation are measured separately. A larger CERA electorate by itself does not establish fraud.
Concern has also grown after a video circulated on social media showing PSOE leaders in Argentina discussing strategies to concentrate new voters in provinces where the PP’s lead could be vulnerable. Overseas ballots have occasionally changed seat allocations, but such outcomes are not routine. In November 2019, for example, the final count in Bizkaia gave the Partido Popular a seat instead of the PNV, complicating Pedro Sánchez’s investiture arithmetic. The episode shows how ballots can matter in a close contest, not that a larger overseas electorate systematically benefits one party.
The debate over overseas voters is longstanding, but the current citizenship process has sharpened scrutiny. The CERA vote has often had limited effects because turnout is relatively low and ballots are spread across provinces, although close contests can be exceptions. As the 2027 elections approach, the PP’s approach contrasts with the more confrontational tactics of other parties. Tensions within Spain’s major parties also reflect wider disputes over electoral strategy. The PSOE’s early primary race in Madrid, for instance, sparked controversy among its own ranks, as detailed in coverage of the PSOE’s internal conflicts.
Spain allocates parliamentary seats by province, so small shifts in votes can matter in close races. The current nationality route was established by the 2022 Democratic Memory Law, which provides certain descendants of exiles with a path to Spanish citizenship. The PP says it will avoid escalating the issue publicly while monitoring the legal proceedings and seeking support among overseas voters.
