Guardia Civil officers have entered the national headquarters of Spain’s ruling Socialist Party in Madrid as part of a judicial investigation linked to former PSOE militant Leire Díez.
The PSOE headquarters inquiry drew immediate political attention on Wednesday after UCO officers went to the party’s Ferraz headquarters. However, both the court and the PSOE have stressed that the action was a request for specific documentation, not a full search of the party headquarters.
RTVE reported that the officers attended the PSOE headquarters by order of Audiencia Nacional judge Santiago Pedraz. The request forms part of an investigation into alleged irregular payments and possible efforts to interfere with judicial proceedings affecting the party or government.
What happened at PSOE headquarters?
The Guardia Civil’s Central Operative Unit, known as the UCO, went to the PSOE’s national headquarters on Calle Ferraz in Madrid on Wednesday morning.
According to Reuters, the High Court said the officers were acting under a judicial order to collect specific material. That included documents and electronic files relevant to the inquiry.
The distinction matters. Some headlines described the operation as a “raid”, but the court’s clarification suggests a more limited action focused on required documentation.
PSOE says it was a document request, not a search
The PSOE said in a statement on X that it had received a documentation request from Court Number 5 of the Audiencia Nacional, as part of proceedings that remain under secrecy. The party stressed that the request was “not a search” and said it was unrelated to illegal financing. It added that the documentation request had been dealt with in full cooperation with the court.

What is the Leire Díez case?
The investigation centres on Leire Díez, a former PSOE militant and journalist who has been linked in Spanish media to alleged attempts to gather damaging information against members of the Guardia Civil and prosecutors.
Reuters reported that the judicial inquiry is examining alleged attempts to interfere with legal proceedings involving the party or the government. Offences under investigation include bribery, misconduct, inducing false testimony, and possible criminal organisation.
RTVE said the case includes allegations of a network operating around Díez and other figures, with the judge examining whether payments and activities were connected to efforts to affect judicial cases.
Senior PSOE figures also under investigation
The case widened further on Wednesday. RTVE reported that the Audiencia Nacional has also named former PSOE organisation secretary Santos Cerdán and former Andalucian vice-president Gaspar Zarrías among those under investigation in an operation linked to Leire Díez.
Spanish media also reported that PSOE manager Ana María Fuentes has been included in the investigation. Reuters said the inquiry includes party members, lawyers, a businessman, and a police officer.
Being placed under investigation in Spain does not mean someone has been tried or convicted. It means a judge considers their testimony or conduct relevant to the inquiry.
Why Ferraz matters politically
Ferraz is not just a building. It is the national headquarters of the PSOE, the party led by Prime Minister Pedro Sánchez.
That makes any judicial action there politically explosive, even when the legal step is limited to collecting documents. Opposition parties quickly seized on the development, while the government and PSOE have stressed cooperation with the courts.
Reuters reported that Sánchez said the party was fully cooperating with judicial authorities and respected the legal process.
PSOE disputes reports of a search
The PSOE said on X that it had received a request for documentation from Court Number 5 of the Audiencia Nacional as part of proceedings that remain under secrecy. The party stressed that the request was “not a search” and said the matter was unrelated to illegal financing.
That position is important because several early reports described the Guardia Civil action as a raid or search. The court and the party have both indicated that officers attended the Ferraz headquarters to collect specific documents and electronic files requested by the judge.
The investigation remains ongoing, and no finding of guilt has been made.
How this links to Spain’s wider political pressure
The Leire Díez inquiry comes at a difficult moment for the PSOE.
Spain is already dealing with the fallout from the Plus Ultra case involving former prime minister José Luis Rodríguez Zapatero, who is separately under investigation in relation to alleged influence-peddling and money laundering. Zapatero denies wrongdoing.
The Ferraz development adds another layer of pressure. It places judicial scrutiny closer to the party’s own administrative structure, even though the facts of the case still need to be established in court.
What happens next?
The immediate next step is for investigators and the court to examine the material requested from the PSOE.
Further summonses, document requests or procedural decisions may follow. For now, the case remains an investigation, not a trial.
For readers in Spain, the key point is clear: the UCO’s action at Ferraz marks a significant escalation in a politically sensitive inquiry, but the legal process is still at an early stage.
