UCO investigation reveals Santos Cerdán allegedly served as the crucial connection between Spain’s Transport Ministry and construction giant Acciona.
According to a new Guardia Civil report, the former PSOE organisation secretary acted as a “link” facilitating irregular public works contracts while receiving personal financial benefits.

The document details how Cerdán allegedly secured “personal profit” through Servinabar, a company with close economic ties to Acciona.

UCO Investigation Details Alleged Corruption Network
The UCO report triggered last week’s raids at various Acciona offices and the indictment of three company executives. Furthermore, the investigation outlines what it describes as a “symbiotic relationship” between Acciona and Servinabar. According to the findings, Servinabar received 2% net of every contract awarded to the construction company through subcontracts with “very generic concepts” and “vague descriptions.”
This operational pattern allegedly occurred in multiple infrastructure projects, including railway integration in Sant Feliu de Llobregat, construction of Seville’s Centenary Bridge suspension cables, and a section of the Logroño motorway. Consequently, the UCO calculates this 2% commission represented at least 75% of Servinabar’s income, making it the company’s “main funding source.”
Meanwhile, Spanish Prime Minister Pedro Sánchez has reiterated that the PSOE has “acted decisively” from the beginning and “collaborated with justice.” During a press conference with Volodímir Zelenski at the Moncloa palace, Sánchez emphasized letting “justice work” through the judicial investigation.
Financial Benefits and Security Measures Exposed
The UCO claims Cerdán and his “family circle” benefited from Servinabar’s assets through various channels. Specifically, his wife received €9,500 while working at Noran, where Servinabar was the primary fund source. Additionally, his sister and brother-in-law were employed by the company and received €77,000 collectively.
Servinabar also allegedly covered housing expenses for Cerdán, including €7,200 in rent between 2017-2018, €44,600 from 2018-2019, and €7,700 worth of furniture purchases. Moreover, the family used a Servinabar credit card for personal expenses totaling €33,574 from December 2021 until February 2024, the day before Koldo García’s arrest.
The investigation reveals extensive security measures taken to maintain privacy. For instance, participants used the encrypted messaging app Threema for communications and held meetings in properties rented specifically for discretion. These developments follow recent concerns about transparency in Barcelona that have drawn public attention.
International Expansion and Government Connections
The corruption network allegedly expanded internationally during José Luis Ábalos’s tenure as Transport Minister, with projects in Morocco and Gabon. Regarding the Moroccan port of Kenitra project, Cerdán provided Koldo García with contact details for two Moroccan government ministers, describing one as being of “full confidence.”
Cerdán subsequently arranged to join the official Spanish government delegation to Morocco. Similarly, in Gabon, the UCO detected interest from Cerdán and Alonso in recovering over €20 million owed to Acciona for road construction and maintenance projects. These infrastructure developments mirror ongoing transport projects transforming Barcelona’s landscape.
The UCO investigation continues to develop as the three Acciona executives face court appearances scheduled for December 3rd. Meanwhile, the judicial process examines whether these alleged activities represent systematic corruption within Spain’s public works contracting system.
