Hungarian intelligence officers linked to Prime Minister Viktor Orbán’s government spent years trying to gather information from inside European Union institutions, according to an investigation published by Telex and jointly carried out by Direkt36, Germany’s Paper Trail Media, and Belgium’s De Tijd. Several diplomats at Hungary’s Permanent Representation in Brussels were in fact covert agents of the Information Office (IH), whose main aim was to obtain details on the EU’s decision-making processes and matters affecting the Hungarian government. The covert operation was uncovered in 2017, leading to serious international repercussions.

Intelligence officers in diplomatic cover

The investigation found that during the 2010s, particularly between 2012 and 2018, several IH officers operated in Brussels under diplomatic cover. The network’s key player, codenamed V., was the leading intelligence officer at the Permanent Representation, officially working there as a diplomat. He claimed his goal was to “build a new Hungarian elite in Brussels” composed of young professionals who could later rise to influential positions within the EU. But V.’s work went beyond symbolic ambitions: according to the report, he made concrete attempts to recruit sources, including a Hungarian EU official working at the European Commission. Instead of offering direct financial incentives, he proposed support for a non-governmental organisation to win them over. The official rejected the offer, but after these meetings, suspicions surrounding V. grew.

Collapse of the network

In 2017, V. was caught, compromising Hungary’s entire intelligence residency in Brussels. Sources claim that the IH had to rebuild its network from scratch. The downfall was attributed to V. and his colleagues ignoring basic security protocols, recruiting too openly, and even communicating via SMS. One source remarked: “He acted recklessly, which drew the EU’s attention.” As a result, Hungarian intelligence lost its position of trust in Brussels for years.

Targeting Hungarian EU officials

The IH’s primary targets were Hungarian EU staff in Brussels rather than foreign nationals. The agency used various approaches: appealing to patriotic duty, promising career advancement, or offering financial backing. Hungarian nationals working at the Commission were carefully profiled using background studies, state databases, and secret reports. After recruitment, the transfer of information usually took place back in Hungary through encrypted communication channels.

Between 2015 and 2019, the head of Hungary’s Permanent Representation in Brussels was Olivér Várhelyi, now serving as European Commissioner at the European Commission. While no direct involvement in covert operations has been proven, multiple sources claim he knew about undercover intelligence officers at the embassy and maintained regular contact with IH leadership. Some Commission insiders allege that he was aware of which Brussels-based staff were working on reports unfavourable to the Orbán government. The European Commission’s spokesperson stated that no ethical or legal complaints had been lodged against him.

Deepening distrust within the EU

The Hungarian spy affair fuelled both political and intelligence tensions within the EU. Belgium’s counter-intelligence service (VSSE) officially declined to comment, but internal sources described the case as “serious”. Gerhard Conrad, former head of the EU’s Intelligence and Situation Centre, stressed that if a diplomat offers money for information, it breaches the Vienna Convention. Officially, Belgium continues to regard Hungary as a “blue” — allied — country, but according to De Tijd, distrust has grown and Hungary is increasingly viewed as “purple”, meaning its loyalty is questioned.

Increased diplomatic presence and surveillance

Despite the scandal, the Orbán government strengthened its Brussels presence. In 2025, eight new diplomats were appointed to the Permanent Representation, including one whose costs are covered by Hungary’s counter-intelligence agency, the Constitution Protection Office. Last year also saw the opening of the Hungarian House in Brussels, officially dedicated to cultural purposes, but Belgian security services consider it a potential intelligence risk.
