Protesters carrying Spanish flags and banners reading “Enough!” gathered in the capital following a call by Sociedad Civil Española, a coalition of more than 150 civic associations. The demonstration was backed by the conservative Alberto Núñez Feijóo-led Popular Party and the far-right Santiago Abascal party.

Organizers estimated attendance at around 80,000 people, while the central government’s representative in the Madrid region put the turnout at roughly half that figure. The march concluded near Plaza Moncloa, close to the prime minister’s official residence.

Speaking before the rally, Vox leader Abascal accused the government of being engulfed in corruption scandals, arguing that allegations involving individuals close to Sanchez had eroded public confidence in the administration.

The demonstration comes amid mounting scrutiny of figures linked to the prime minister. Sanchez’s brother, David Sanchez, is due to stand trial on influence-peddling charges, while his wife, Begona Gomez, remains under investigation in a separate corruption inquiry. Sanchez has repeatedly rejected the allegations and described the cases as politically motivated.

Pressure on the government has also increased following legal proceedings involving former transport minister Jose Luis Abalos, a longtime Sanchez ally whose corruption trial concluded earlier this month and is awaiting a verdict.

Adding to the political challenges facing the government, a Spanish court this week placed former prime minister Jose Luis Rodriguez Zapatero under formal investigation for alleged influence peddling and other offenses. Zapatero has been regarded as a close ally of Sanchez within Spain’s Socialist movement.

Sanchez, who came to power in 2018 after a no-confidence vote removed a conservative government plagued by corruption scandals, has insisted he will remain in office despite growing opposition demands for early elections.

The rally underscored the increasingly polarized political climate in Spain, where corruption allegations have become a central battleground ahead of future electoral contests.
