Hungarian Spy Row Hits Brussels

The charge against Hungary is not simply that it spied in Brussels. States spy in Brussels. The more awkward allegation is that Hungarian intelligence officers used Hungary's own EU mission as a base for a years-long operation targeting European Commission staff.

A joint investigation by Direkt36, Der Spiegel, Der Standard and De Tijd reported that the Commission opened a probe into the claims, then paused it, reportedly to avoid giving Viktor Orbán's government another line of attack against "Brussels" at home (Direkt36).

The Commission has never publicly settled the central question. In May 2026, it cleared Olivér Várhelyi, Hungary's former Commissioner, of personal involvement. But it did not answer whether Hungarian officers collected intelligence on EU staff and files from within the machinery of the Union itself (Euronews).

The Spying Came From Inside the Room

The alleged operation matters because of where it took place. Hungary's Permanent Representation is not a normal embassy observing the EU from the outside. It is part of the system.

Its diplomats sit in Coreper, the Committee of Permanent Representatives that prepares Council decisions, and in the working groups where member states negotiate EU laws line by line (Council). If intelligence officers were operating under diplomatic cover from that mission, they were not peering in through the window. They were already at the table.

The allegations go back to 2013, when Hungary's Information Office reportedly began profiling Hungarian nationals working in EU institutions. From 2015, the operation is said to have become more aggressive, with officers allegedly seeking sensitive EU files. One officer was reportedly exposed in 2017, compromising the wider network (Direkt36).

Separately, Hungarian services allegedly monitored investigators at OLAF, the EU's anti-fraud office, while they were examining a company linked to Orbán's son-in-law (EUNews).

The European Parliament passed a resolution in November 2025 urging the Commission to publish findings quickly and to impose consequences if the claims were proven (European Parliament). Eight months on, there has been no public judicial or institutional conclusion.

Where EU Power Runs Out

The EU has tools for budget fraud, breaches of EU law and rule-of-law backsliding. It has used them against Hungary. In late 2022, the Council froze billions in Hungarian cohesion funding, the EU money meant to narrow economic gaps between regions, over rule-of-law concerns (CER). The European Parliament's Article 7 procedure, the Union's formal mechanism for dealing with systemic democratic decline, has been open against Hungary since 2018.

Intelligence is different. National security remains the responsibility of each member state under the EU treaties (Article 4 TEU). The EU's own threat-analysis body, INTCEN, can assess risks but cannot investigate or enforce anything (EEAS).

Belgium, as host state, has territorial jurisdiction. But diplomatic immunity sharply limits what Belgian authorities can do inside a Permanent Representation without consent. For the EU to act, the alleged spying would have to fit another legal category: bribery of EU officials, misuse of EU funds, or a wider rule-of-law case. Intelligence collection under diplomatic cover sits in the gap between political outrage and legal remedy.

Who Worries Most

The unease is strongest in countries already watching Russian influence closely. Polish media have placed Orbán's Hungary firmly in the category of internal EU risk linked to Russia (Onet). Estonian officials have treated internal EU divisions over Russia sanctions as a strategic danger, not merely an inconvenience in the Council calendar (ERR).

For those states, the practical question is blunt enough: how much sensitive discussion on sanctions, defence and Ukraine can safely happen in rooms where every member state has a seat?

Hungary's post-Orbán government under Péter Magyar has begun taking apart parts of the old intelligence architecture. Hungary's parliament recently voted to abolish the Sovereignty Protection Office, an Orbán-era body long criticised in Brussels (Le Monde).

That may ease the Hungary problem. It does not solve the EU problem. There is still no Commission file, Belgian judicial decision or institutional reform that answers what happens when a member state uses its place inside the room to gather intelligence on the people making EU law.
