MADRID, April 6 – New polling data reveals that Spain’s Socialist Party has experienced a boost in voter approval following Prime Minister Pedro Sanchez’s firm stance against the U.S.-Israeli military campaign targeting Iran, while the far-right Vox party’s support has weakened, according to two surveys released Monday.
Sanchez has positioned himself among the most outspoken Western leaders condemning what he describes as an unlawful and dangerous military action, taking concrete steps including shutting down Spanish airspace to American aircraft participating in the strikes and prohibiting their use of shared military installations in Spain’s southern region.
The far-right Vox party – which maintains close ties to U.S. President Donald Trump’s MAGA movement – has strongly condemned Sanchez’s position on the conflict.
Recent polling by the state-run CIS organization revealed that 85% of Spanish citizens oppose the military action.
Fresh survey results from Sigma Dos, conducted for El Mundo newspaper, indicate the Socialist Party’s support climbed to 27.7% from the previous month’s 26.4%, narrowing the gap with the conservative People’s Party (PP). A separate poll by 40dB for El Pais newspaper placed Socialist support at 28.6%, representing an increase from 27.7%.
Conversely, Vox experienced a decline to 17.1% in April from 18.3% according to Sigma Dos polling, while the 40dB survey showed a smaller decrease of 0.1 percentage point to 18.7%.
The People’s Party maintained its lead in both surveys, capturing 32.5% and 31.1% of voter preferences respectively, with modest gains of less than one percentage point in each poll. The party has criticized Sanchez for harming Atlantic alliance relationships and has avoided publicly condemning Trump and Israel, although its leadership has adopted the “no to war” message.
Both surveys indicate a notable pattern of voter migration from political extremes toward the two major mainstream parties. The People’s Party appears to be preventing further voter defection to Vox, while the Socialists are attracting previous supporters of Sumar, their hard-left coalition partner.
Despite these shifts, Spain’s divided political landscape continues to require coalition governments, with both polls suggesting a potential right-wing majority if elections occurred today.
The country’s next scheduled general election is set for August 2027.
Both polling organizations surveyed approximately 2,000 respondents, with each study carrying a 2.2% margin of error.
