Guardia Civil report finds Santos Cerdán received €323,000 from Servinabar and had unexplained cash income
The Guardia Civil's UCO has sent a report to the Audiencia Nacional detailing alleged undeclared income of former PSOE secretary Santos Cerdán, including €323,178 from a company linked to public works contracts and €18,261 in unexplained cash.
The UCO report
On Friday 17 July 2026, the Central Operative Unit (UCO) of the Guardia Civil delivered a detailed patrimonial analysis of Santos Cerdán to judge Ismael Moreno at Spain's Audiencia Nacional. The document forms part of the "Koldo case", a sprawling investigation into alleged rigging of public works contracts. Cerdán, who served as the PSOE's secretary of organization (the party's number two or three, depending on the period), is charged with criminal organization, influence peddling and bribery. The UCO concludes that Cerdán enjoyed "undeclared sources of income" and handled significant amounts of cash during the ministerial tenure of José Luis Ábalos, who headed the transport ministry.

Servinabar and the Acciona connection
The report states that Cerdán and his family received 323,178.41 euros from Servinabar between 2015 and 2024. Servinabar, a company in which Cerdán held a 45% stake according to investigators, was the vehicle for alleged kickbacks from rigged public works contracts awarded by Adif and the Directorate General of Roads. The company's sole administrator was Joseba Antxon Alonso, a friend and business partner of Cerdán. The UCO found that 87.04% of Servinabar's income came from Acciona or projects linked to it. Acciona was the main beneficiary of the contracts under investigation. The benefits from Servinabar peaked between 2019 and 2023, coinciding with Acciona being awarded the investigated contracts. The Guardia Civil notes that the payments to Cerdán reached "their maximum" during the "ministerial stage of Ábalos".
Unexplained cash and vehicle payments
Between 2014 and 2017, Cerdán deposited 18,261.56 euros in cash of unknown origin into his accounts. From 2019 onward, he reduced his card spending and cash withdrawals, a pattern the UCO links to the period when Acciona was winning the contracts. The report also notes that Koldo García, a former advisor to Ábalos, and his wife Patricia Úriz paid cash to Cerdán to cover the leasing installments of a vehicle. Additionally, Cerdán settled expenses with the PSOE that exceeded the amounts observed in his bank accounts for "concepts susceptible to being claimed". The UCO also found irregularities in expense claims submitted to the PSOE and the Congress of Deputies.
A one-million-euro property that never materialized
The UCO report reveals that Servinabar negotiated the purchase of a one-million-euro property for Cerdán, although the transaction was never completed. Cerdán has denied being the owner of the construction company as part of his defense strategy. The report states that Cerdán attempted to distance himself from Servinabar, but the UCO's analysis of his financial flows suggests otherwise.
Legal and political fallout
Cerdán's income spiked during Ábalos's time as minister and after he replaced Ábalos as the PSOE's secretary of organization. The report has been sent to the judge as the investigation continues. Cerdán faces charges of criminal organization, influence peddling and bribery. The case has drawn attention to the ties between the construction giant Acciona and the former PSOE leadership. The UCO's findings are likely to intensify scrutiny on the party's handling of public contracts during the Sánchez government.
