Officers from the Civil Guard’s Central Operative Unit (UCO) spent 12 hours at the PSOE’s national headquarters in Calle Ferraz on Wednesday as part of an investigation into the so‑called Leire Díez case.
The operation, ordered by National Court judge Santiago Pedraz, is seeking documents on alleged payments by the party to a network whose alleged aim was to obstruct judicial investigations affecting Spanish Prime Minister Pedro Sánchez's inner circle.
The judge considers a meeting held at Ferraz on 26 April 2024, in the middle of the “reflection period” announced by the prime minister, as particularly significant in the case.
According to the court order, the PSOE party is alleged to have allocated 178,000 euros to this alleged structure to discredit judges such as Beatriz Biedma, Mercedes Ayala and Juan Carlos Peinado.
Judge Pedraz has charged former Organisation Secretary Santos Cerdán, former deputy head of the Andalusian regional government Gaspar Zarrías and PSOE manager Ana María Fuentes and is investigating alleged payments to Leire Díez for her alleged interference with judicial proceedings. Díez was arrested in December 2025 and released on bail.
