Spain’s political landscape has barely changed over the past two months despite the growing fallout surrounding ex-prime minister Jose Zapatero and the Plus Ultra corruption probe.

A DYM poll for Grupo Joly newspapers between May 20 and 22, was conducted shortly after National Court judge Jose Luis Calama placed Zapatero under investigation.

Despite the political storm, voting intentions remain largely stable.

The poll of 1,009 people suggests the Partido Popular (PP) would receive 34.8% of the vote if a general election were held today – only slightly higher than the 34.6% recorded in March.

Meanwhile, the ruling PSOE would fall marginally from 27.9% to 27.7%.

According to the survey, opposition leader Alberto Nuñez Feijoo would secure between 144 and 148 seats in Congress.

Combined with Vox, which rose slightly to 16% support and an estimated 54 to 56 seats, the right-wing bloc would comfortably surpass the threshold for an absolute majority in parliament.

On the left, PSOE would retain between 107 and 111 seats despite the Zapatero scandal.

The poll also showed modest growth for Sumar, which climbed from 4.9% to 5.7%, while Podemos slipped slightly to 3.5%.

The survey paints a bleak picture for Spain’s political leaders overall, with none achieving a passing approval rating.

Prime Minister Pedro Sanchez and Feijoo were tied as the country’s most positively rated leaders, both scoring 3.7 out of 10.

However, Sanchez still led comfortably when respondents were asked who they preferred as prime minister, with 42.9% support compared to Feijoo’s 36.6%.

The poll also examined the impact of Zapatero’s legal troubles on public opinion.

According to the findings, 71% of respondents believe the investigation is damaging or very damaging to PSOE’s image, while 64.5% said it negatively affects the Spanish government.

A further 63.5% believe the case harms Spain’s international reputation.

More than half of those surveyed – 51.4% – said they considered the accusations against Zapatero credible to some extent.

Meanwhile, only 24.8% found Zapatero’s own denials convincing, while 51.7% described his explanations as not very credible or completely unconvincing.

The poll also explored the possibility of a future ‘super Sunday’ election in which Spain’s general and municipal elections could be held on the same day in May 2027.

According to the survey, 57.2% of respondents support combining the two votes, while nearly two-thirds said they would vote for the same party in both elections.
