POLICE searched the headquarters of Spain’s governing Socialist Party on Wednesday as part of an investigation into possible financial wrongdoing.

The raid is linked to former party members who allegedly tried to influence police and legal cases.

The search of the office, in central Madrid, is another blow to the party of Prime Minister Pedro Sanchez, whose Socialists have been hammered by a series of corruption scandals linked to close confidants, including his wife and brother.

“We respect the justice system, we will collaborate with the courts and there is the commitment in the Socialist Party that if there are new episodes of improper behavior, we will act with the same firmness we always have,” Mr Sanchez told a news conference.

Mr Sanchez has not been named in any investigation.

A court statement issued on Wednesday said that judge Santiago Pedraz ordered the Civil Guard to “confiscate diverse documentation and electronic archives in an investigation of a ring designed to destabilise judicial processes that were affecting the ruling party.”

The case started in 2025, when audio recordings appeared in Spanish media of then-party member Leire Diez apparently involving himself in attempts to discredit a member of the Civil Guard’s anti-corruption unit.

Ms Diez, who has since left the party, denies wrongdoing.
