UCO agents seek more PSOE donation data from the Tribunal de Cuentas in Koldo case probe

The visit to the auditor

Agents of the Unidad Central Operativa (UCO), the Guardia Civil's central investigative unit, went to the headquarters of the Tribunal de Cuentas, Spain's public audit court, on Thursday, 12 November 2026. They acted on the orders of Audiencia Nacional judge Ismael Moreno, according to sources close to the investigation cited by Europa Press and EFE. The agents want more documentation on donations to the Spanish Socialist Workers' Party (PSOE), which the auditors have been examining. According to EFE's sources, a court clerk was present while the requests were made. The inquiry is being run as a secret judicial strand.

Why the agents went back

The visit is one more step in a procedure that has already produced several information requests, according to LaSexta. Sources told EFE that investigators compared the material the court previously supplied with the PSOE's own records and found that some items did not match. La Razón reports that the new request complements the documentation the auditor sent in September 2026. Investigators are also working through the list of cash payments the PSOE handed over in December 2025, which covers 2017 to 2024.

Origins of the secret strand

Judge Moreno opened this separate piece within the caso Koldo, which El Periódico says he began last year. El Confidencial reports that the proceedings have been secret since October 2025. The inquiry grew out of anomalies the Guardia Civil found while analysing cash payments the PSOE made to former transport minister José Luis Ábalos and his former adviser Koldo García. El País says the strand was opened at the request of Supreme Court magistrate Leopoldo Puente, who had handled the investigation into Ábalos and García. LaSexta adds that the strand also drew on testimony by Koldo García in a Supreme Court trial and on documents from the intermediary Víctor de Aldama about an alleged Venezuelan funding route.

What the donations cover

El Confidencial reports that the judge is examining donations received by Pedro Sánchez's candidacy in the 2017 party primaries. The same outlet says the review also covers all in-kind donations received by Ferraz, the party headquarters, and contributions from members and public officials. Certain properties that entered the party's assets in 2019, located in the Burgos and Vizcaya provinces, are also drawing attention. The auditor had already given the court, in a sealed envelope, a memory device with a list of the party's donors over the last decade. Investigators are checking that list against the PSOE's accounts, including receipts for cash payments.

Open questions

The strand remains secret, and the reports describe requests for documents rather than charges or findings. Investigators are still cross-checking the auditor's donor list against the PSOE's accounts.
