A report by Spain’s elite anti-corruption unit, the UCO (Unidad Central Operativa of the Guardia Civil), has placed infrastructure giant Acciona at the heart of a wide-ranging political corruption network allegedly coordinated from the top ranks of the Socialist Party (PSOE). According to the investigators, the company paid hundreds of thousands of euros in illicit commissions to secure major public contracts. These bribes were allegedly funneled through political operatives closely tied to former minister José Luis Ábalos and the party’s former Organization Secretary, Santos Cerdán.
Over €600,000 in Illicit Payments
The UCO report outlines transactions amounting to a minimum of €620,000 related to certain public contracts granted to Acciona. The transfers were allegedly facilitated through intermediaries associated with Ábalos and his close confidant Koldo García, with the whole scheme managed and orchestrated by Santos Cerdán.
Researchers found clues about an extra €450,000 in pending kickbacks linked to three more public agreements, indicating that the suspected corruption ring was not limited to a single instance but was continuing, despite initial warnings of inconsistencies emerging.
Agreements Designed to Benefit Acciona
The contracts in question include large-scale infrastructure projects between 2018 and 2021—such as roadworks, railway development, and urban transport systems—primarily in regions governed by the PSOE. According to the UCO, these tenders were not the product of fair competition, but rather structured with technical requirements that effectively excluded competitors, ensuring Acciona’s success.
The document describes the procedure as part of a “meticulously orchestrated framework” where political influence was leveraged to manipulate the bidding process in return for monetary incentives.
The Key Role of Santos Cerdán
An essential aspect of the UCO investigation involves Santos Cerdán’s involvement. The report claims that Cerdán was aware of the bribery operation and orchestrated the handling and allocation of funds. Documented conversations and witness accounts indicate that he was the key political player coordinating the connection between business interests and senior political power.
As reported by researchers, Cerdán was responsible for managing discussions, determining shares, and serving as the intermediary between the grantors and those benefiting from the arrangement.
Quietude in Institutions and Internal Evaluations
Acciona has launched an internal review, publicly distancing itself from any wrongdoing. One former executive allegedly linked to the scheme has already left the company. Although Acciona claims ignorance of any irregularities, the UCO report suggests otherwise, painting a picture of a company that either actively participated or turned a blind eye to corrupt practices.
Even with the gravity of the accusations, the government has not issued any official comment. Within the PSOE, the issue has turned into a significant problem, particularly following recent prominent resignations caused by earlier stages of the corruption inquiry.
The findings in the UCO report are quite clear: Acciona is supposedly involved in a larger politically driven scheme aimed at obtaining bribes in return for public contracts worth millions of euros. Should this be validated, the case would reveal an extensive corruption network embedded not just among political actors but also within the agencies tasked with overseeing public funds.
This is no longer a matter of internal party misconduct—it is a potential scandal of national magnitude. The public will now wait to see whether the courts and political institutions have the will to pursue full accountability, regardless of how high the investigation reaches.
