Belgian Police Raid EU Diplomatic Service, Detain Three Including Mogherini

Belgian federal police carried out coordinated raids on December 2, 2025 at offices of the European External Action Service in Brussels and at the College of Europe campus in Bruges, detaining three people for questioning as part of an inquiry led by the European Public Prosecutor’s Office. The EPPO said it had strong suspicions that confidential procurement information related to the 2021 to 2022 tender for the European Union Diplomatic Academy had been shared improperly, and that the conduct could amount to procurement fraud, corruption, conflict of interest and violation of professional secrecy.

Authorities searched several institutional offices and private residences in the course of the operation. Belgian media and multiple outlets reported that one of those detained is Federica Mogherini, the former EU foreign policy chief who has served as rector of the College of Europe since 2020. Officials cautioned that the detainees are presumed innocent and that the investigation is ongoing.

The EPPO, which began operations in 2021 to protect the EU budget from criminal activity, has been increasingly active in pursuing cases that cut across national borders. This probe is notable because it targets the EU diplomatic service and a prominent educational institution that trains diplomats and officials from across the bloc. The allegation that confidential procurement information was improperly shared strikes at the heart of EU procurement rules designed to ensure fair competition and safeguard public funds.

Beyond the immediate legal ramifications, the case poses policy and governance questions for Brussels. EU institutions collectively manage a budget of hundreds of billions of euros across multiple programmes and depend heavily on external contractors for training and advisory services. Even the appearance of irregularities can prompt member states and the Commission to tighten oversight, revise procurement procedures, and expand internal audit capacity. The EPPO’s involvement signals that Brussels and national authorities are prepared to escalate enforcement when cross border financial interests are implicated.

Markets are unlikely to react sharply to a single procurement probe, but the incident feeds into a broader narrative about institutional transparency and rule of law that investors monitor when assessing political risk in Europe. For firms that regularly bid for EU contracts, the case may mean stricter compliance demands and more intrusive auditing in future tenders. For member states and the European Commission, it will increase pressure to demonstrate the integrity of procurement processes, particularly for contracts that carry reputational weight.

Longer term, the investigation could accelerate reforms already under discussion to centralize and professionalize procurement for cross border EU programmes. It may also spur calls for clearer firewalls between institutional decision makers and external providers. For now, officials and the EPPO are conducting enquiries, and the full facts have yet to be established. The detained individuals must be treated as suspects under investigation until evidence warrants charges.
