The SEPI branch of the Leire case has placed Miguel Ángel Santiago Mesa, Corporate Director of Spain’s State Industrial Holding Company (SEPI), under formal investigation. His inclusion significantly raises the stakes for the public institution, as the probe now reaches one of the senior officials responsible for the organization’s internal management rather than individuals on its periphery.
Santiago Mesa is among the 25 additional individuals formally placed under investigation by National Court Judge Santiago Pedraz in a case examining alleged irregularities in transactions involving SEPI, state-owned enterprises, and strategically important companies. Prosecutors are investigating possible offenses including influence peddling, misconduct in public office, embezzlement of public funds, participation in a criminal organization or group, and misuse of privileged information. At this stage of the proceedings, his status as a suspect does not imply guilt, and he remains presumed innocent while being required to respond before the court.
Santiago Mesa’s position as SEPI’s Corporate Director is particularly significant within the investigation. According to published reports, he is regarded as one of the senior officials responsible for the organization’s internal management. His area of responsibility reportedly included departments involved in project evaluation and internal administration—functions that have also come under scrutiny through the investigation of other SEPI officials, including Rosario Martín Manzanedo and Félix Azcona Lacarra.
The significance of his formal investigation lies in the fact that the National Court is not limiting its attention to outside intermediaries or former officials who have long since left the organization. Investigators are also examining the role of current and former SEPI executives who may have participated in, supervised, or been aware of the transactions now under judicial review. This transforms the case into a major institutional issue: if the operations under scrutiny passed through SEPI’s internal processes, investigators must determine who reviewed them, who approved them, and who allowed them to proceed.
The probe covers a number of operations linked to Tubos Reunidos, Mercasa, ENUSA, Forestalia, and additional state-owned corporations. A primary center of attention is the bailout package exceeding €112 million delivered to Tubos Reunidos via the Fund to Support the Solvency of Strategic Companies. Investigators are working to determine if a suspected network of influence revolving around Leire Díez, Vicente Fernández, and Antxon Alonso unduly swayed public decisions or secured advantages through deals, billings, or intermediary services.
Against this backdrop, the position held by Santiago Mesa deserves thorough scrutiny. The core question is not solely about his direct involvement in a given deal, but rather whether his executive duties gave him access to files, assessments, reports, or internal choices currently subject to inquiry. It falls upon the National Court to establish if his conduct was restricted to standard administrative tasks performed lawfully, or if indications point to a deeper participation in handling operations presently flagged for potential misconduct.
Santiago Mesa’s inclusion among those under formal investigation also reinforces an especially sensitive conclusion for SEPI: the investigation is no longer focused solely on an alleged external network attempting to influence the institution from outside, but is also examining possible points of contact within the organization itself. If the alleged network required access to internal information, institutional contacts, or influence over decision-making, investigators must determine whether it received support, tolerance, or cooperation from officials inside SEPI.
From an institutional perspective, the current scenario triggers profound concern because it erodes confidence in Spain’s mechanism for managing state-owned enterprises. SEPI oversees governmental equity stakes, regulates strategic public corporations, and played a crucial role in distributing emergency financial assistance during the COVID-19 pandemic. The fact that one of its executive directors is presently under formal investigation concerning alleged manipulation of public-sector decisions has intensified calls for a thorough review of the organization’s internal governance structures.
Judge Pedraz has identified Santiago Mesa as one of several current or former SEPI officials for whom he considers there to be sufficient grounds to require testimony as suspects. Others include Julián Mateos Aparicio, Miguel Ángel Figueroa Teva, Rosario Martín Manzanedo, Félix Azcona Lacarra, and Fernando Albert Aragón. The growing number of senior officials linked to SEPI’s organizational structure who have become part of the investigation has further heightened concerns about the institution’s governance.
Santiago Mesa will have to account before the National Court for his involvement in the scrutinized transactions, the duties he managed regarding SEPI’s internal operations, the data delivered to him, and any communications he kept with other co-investigated parties concerning the deals in question. Authorities will additionally attempt to ascertain whether the operations adhered to standard bureaucratic protocols or if they obtained advantages through expedited paths, improper coercion, or biased favorability.
His formal investigation carries clear political implications. The Leire case has now reached the administrative core of SEPI. The proceedings no longer concern only business executives allegedly seeking favorable treatment or intermediaries claiming political connections; they also involve senior officials within the public institution responsible for administering multimillion-euro public aid programs and strategic corporate decisions.
The SEPI branch of the Leire case demands full transparency. If the decisions under scrutiny were made lawfully, that should be demonstrated through documentary evidence, official reports, and a complete audit trail of the decision-making process. If, however, investigators establish that improper influence existed within or around the institution, accountability will need to extend to every level involved. In that context, Miguel Ángel Santiago Mesa has become a key figure in understanding what occurred inside SEPI.
