Hungarian spies operated from inside EU mission

Hungarian intelligence officers allegedly ran a years-long operation from inside Hungary's own EU mission in Brussels, 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 allegations but paused it, reportedly to avoid fuelling anti-EU sentiment in Budapest (Direkt36).

The Commission has not publicly resolved the core allegations. In May 2026, it cleared former Commissioner Olivér Várhelyi, Hungary's appointee to the Commission, of personal involvement, but the question of whether Hungarian officers collected intelligence on EU staff and files remains unanswered (Euronews).

The Spying Came From Inside the Room

The alleged spying matters because it came from inside the EU's lawmaking machinery. Hungary's Permanent Representation is not an embassy watching from across the street. National diplomats posted there sit in Coreper (the Committee of Permanent Representatives, which prepares all decisions for the Council of the EU) and in dozens of working groups where member states negotiate legislation line by line (Council). If intelligence officers worked under diplomatic cover from that mission, they operated at the centre of how EU law gets made.

The allegations stretch back to 2013, when Hungary's Information Office reportedly began profiling Hungarian nationals working in EU institutions. The operation grew more aggressive from 2015, 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) who were looking into a company linked to Orbán's son-in-law (EUNews).

The European Parliament adopted a resolution in November 2025 urging the Commission to deliver findings quickly and demanding consequences if the allegations proved true (European Parliament). Eight months later, no public judicial or institutional finding has followed.

Where EU Power Runs Out

The EU can punish budget fraud, rule-of-law breaches and violations of EU law. It has used those tools against Hungary: the Council froze billions in Hungarian cohesion funding in late 2022 over rule-of-law concerns (CER). The European Parliament's Article 7 procedure (the EU's mechanism for addressing systematic democratic backsliding) has been open against Hungary since 2018.

Intelligence gathering by a member state's diplomats sits where EU power runs out. The EU Treaty reserves national security to each member state (Article 4 TEU). The EU's own threat-analysis body, INTCEN, can assess risks but has no authority to investigate or act (EEAS). Belgium has territorial jurisdiction as host state, but diplomatic immunity limits what Belgian authorities can do inside a Permanent Representation without consent. For the EU to respond, the alleged spying would have to be reclassified as something else: bribery of EU officials, misuse of EU funds, or a broader rule-of-law case. Pure intelligence collection under diplomatic cover does not fit any available box.

Who Worries Most

The concern is sharpest in member states already focused on Russian influence. Polish media place Orbán's Hungary squarely in the category of internal EU risk tied to Russia (Onet). Estonian officials have treated internal EU divisions on Russia sanctions as strategically dangerous, not just procedurally awkward (ERR). The practical question for these states: how much sensitive deliberation on sanctions, defence and Ukraine should be shared in rooms where every member state has a seat?

Hungary's post-Orbán government under Péter Magyar has begun dismantling parts of the old intelligence architecture. Hungary's parliament recently voted to abolish the Sovereignty Protection Office, an Orbán-era body that Brussels had long criticised (Le Monde). That political change may resolve the Hungary problem. It does not resolve the EU problem. No Commission file, no Belgian judicial decision and no institutional reform has addressed what happens the next time a member state uses its seat inside the room to collect intelligence on the people negotiating EU law.
