Thousands rally in Madrid demanding PM quit over graft allegations

Demonstrators, many waving red and yellow Spanish flags and brandishing signs saying "Enough!", made their way through the streets of Madrid behind a large banner that read: "Corruption has a price. No more impunity. Resignation and elections now."

The protest was called by a group of over 150 civic associations called Sociedad Civil Española and backed by the mainstream conservative Popular Party (PP) and far-right Vox.

Organisers put attendance at 80,000.

The central government's delegate to the region estimated that half that many people had turned out for the march, which ended in Plaza Moncloa near Sánchez's official residence.

"There is no-one left in Pedro Sánchez's circle who has not been accused of very serious crimes. Spain is being held hostage by a corrupt mafia," far-right Vox leader Santiago Abascal told reporters before the start of the march.

Sánchez, who came to power in 2018 after using a vote of no-confidence to topple the corruption-mired conservative PP government, has vowed to carry on despite the proliferation of graft allegations concerning his entourage.

His brother, David, is scheduled to stand trial for influence peddling.

His wife, Begoña Gómez, is under investigation in a separate corruption case.

Sánchez has dismissed these cases against his family as politically motivated.

His former right-hand man, ex-transport minister José Luis Ábalos, is awaiting a verdict in his own corruption trial which ended earlier this month.

On Tuesday, a court put former Socialist prime minister Jose Luis Rodriguez Zapatero, a Sanchez ally, under formal investigation for influence peddling and other crimes, adding to the pressure on the government.
