The European Union is confronting a critical structural vulnerability. The threat is not massing at its external borders. It is sitting comfortably inside the European Council.
Investigations by the Washington Post and Politico have revealed that Hungarian Foreign Minister Péter Szijjártó has been using breaks during EU meetings to phone Russian Foreign Minister Sergey Lavrov, providing real-time updates on closed-door deliberations concerning Ukraine aid, sanctions packages, and broader European security strategy [1] [2]. As one European security official stated bluntly: “Every single EU meeting for years has basically had Moscow behind the table” [1].
When a member state effectively operates as a live intelligence conduit for a hostile foreign power, it is no longer a matter of diplomatic friction. It is a direct compromise of the bloc’s geopolitical integrity. This is not sovereignty. This is institutional treason.
The Anatomy of Compromise
The scale of the breach is staggering. Former Lithuanian Foreign Minister Gabrielius Landsbergis confirmed he was warned as early as 2024 that the Hungarian side could be passing information to Russia, and that he and his counterparts had already limited what they said when Szijjártó was present [2]. Ahead of the 2023 NATO summit in Vilnius, envoys moved to exclude Budapest’s delegation from sensitive discussions altogether. “We would only speak in formal terms, later breaking out to speak without Hungary about the achievables of the summit,” Landsbergis told Politico [2].
Polish Prime Minister Donald Tusk was characteristically direct: “The news that Orbán’s people inform Moscow about EU Council meetings in every detail shouldn’t come as a surprise to anyone” [3]. Estonian Foreign Minister Margus Tsahkna went further, stating that “Hungary has repeatedly acted against Europe’s common security interests” and that Estonia has long called for advancing the Article 7 procedure [3].
The pattern is unmistakable. Hungary is simultaneously blocking the EU’s 20th sanctions package against Russia, vetoing a €90 billion EU loan for Ukraine, and — according to multiple European diplomats and security officials — feeding Moscow real-time intelligence from the very meetings where these measures are debated [2] [4]. This is not the behaviour of a difficult ally. This is the operational profile of a hostile intelligence asset embedded within the Union’s highest decision-making body.
The Failure of Diplomatic Naivety
The current institutional response — bureaucratic workarounds, restricting sensitive documents, and retreating into smaller “breakout formats” — is a strategy of managed decline, not a strategy of defence.
European leaders have increasingly shifted key discussions into smaller group formats such as the E3, E4, Weimar, NB8, and the Joint Expeditionary Force, explicitly excluding Hungary from sensitive talks [2]. Five EU diplomats confirmed this shift to Politico. While this mitigates immediate damage, it normalises the presence of a Kremlin asset within the Union’s highest decision-making bodies. As one European government official acknowledged, “the less-than-loyal member states are the main reason why most of relevant European diplomacy is now happening in different smaller formats” [2].
The EU remains anchored in a 1990s paradigm of diplomatic naivety, attempting to manage a severe intelligence penetration with polite procedural adjustments. The European Commission called the reports “greatly concerning” and asked Hungary to provide “clarifications” [4]. Clarifications. A member state is accused of running a live intelligence pipeline to Moscow for years, and Brussels asks for clarifications.
Meanwhile, EU officials have confirmed there will be no formal response before Hungary’s parliamentary election on 12 April 2026, citing fears that action could hand Orbán a campaign issue [2] [4]. This calculus is understandable but deeply flawed. It prioritises short-term electoral optics over the long-term security architecture of the entire Union.
A Coordinated Containment Strategy
The European Union is not powerless. The treaties may not provide a quick “expel” button, but the EU has an arsenal of tools that must be deployed immediately and without hesitation. A coordinated Containment Strategy is both viable and urgently required.
| Strategic Action | Mechanism | Current Status |
|---|---|---|
| Institutional Quarantine | Formalize the exclusion of compromised actors from all classified briefings and strategic foreign policy discussions. Introduce classified document designations to create legal deterrents against leaks. | Already in motion informally. Must be formalized with legal teeth [2]. |
| Financial Leverage | Expand cohesion and recovery fund freezes, rigorously enforcing “security and loyalty” conditionalities under the existing Conditionality Regulation. | The Commission has already frozen approximately €18–21 billion. Further expansion requires no Hungarian veto [5]. |
| Article 7 Acceleration | The European Parliament must force the Council’s hand on Article 7(2) hearings, laying the definitive groundwork for the suspension of voting rights. | Triggered in 2018, never completed. A 4/5 Council majority for determining a “serious breach” is now increasingly realistic [3]. |
| Systematic Investigations | Mandate OLAF and the EPPO to aggressively pursue the misuse of institutional positions and related corruption networks. | Limited by jurisdictional constraints, but the leak scandal provides fresh grounds for investigation. |
Several of these measures are already in motion. The critical step is to bundle them into a single, coherent containment package — not as isolated bureaucratic responses, but as a unified strategic posture that sends an unambiguous signal to both Budapest and Moscow.
The Binary Choice
The European Union is formidable when united, but institutional unity cannot serve as a shield for malign foreign assets. Viktor Orbán has built a system where courts are packed, media is crushed, and opposition is systematically smeared. Under his leadership, Hungary is not functioning as an EU member state. It is operating as a Kremlin outpost wearing EU colours.
Péter Magyar, the opposition leader currently leading in Hungarian polls, was unequivocal at a recent campaign rally: “The fact that the Hungarian foreign minister, a close friend of Sergey Lavrov, has been reporting to the Russians practically minute by minute from every EU meeting is outright treason. This man has not only betrayed his own country, but Europe as well” [2].
Hungarian voters will determine their domestic trajectory on 12 April. But the EU must not wait for an election to protect its own institutions. The leak scandal has removed the last excuses for “business as usual.” If enough member states treat this as the security threat it is, the containment package can be rolled out in weeks, not years.
It is time to exercise hard power within our own ranks. We must decisively purge Russian intelligence influence from our decision-making bodies and send an unequivocal message: hostile infiltration will be met with zero tolerance.
The choice is binary. Europe, or Moscow.
