Brussels trust crisis deepens: diplomats warn the next Hungarian government will inherit years of suspicion

No matter who forms Hungary’s next government after the election, Brussels is preparing for a difficult and deeply cautious relationship with Budapest.

According to diplomatic sources cited by Portfolio, the recent leak scandal surrounding alleged high-level Hungarian contacts with Moscow has pushed EU concerns beyond political disagreements and into the realm of institutional trust and security.

European officials now reportedly view the issue as a systemic problem that will shape Hungary’s post-election standing regardless of whether Prime Minister Viktor Orbán remains in power or Péter Magyar’s Tisza Party takes office. Recent Brussels reporting similarly suggests EU institutions are preparing two separate scenarios, but neither involves an immediate return to “business as usual”.

The mood hardened further after European Commission spokesperson Paola Pinho said the allegations raised the “deeply troubling possibility” that a member state government may have cooperated with Russia in ways that undermine the EU’s security interests.

That alone signals a major escalation: the matter is no longer being treated as a routine dispute over Hungary’s maverick policies, but as a question of whether sensitive EU deliberations and joint strategic decisions can safely include Budapest.

Why Brussels believes this is bigger than another political row

The current crisis did not emerge overnight. For years, Hungary’s clashes with Brussels have centred on rule-of-law disputes, frozen EU funds, Ukraine policy, sanctions, and repeated vetoes and veto threats. But the newly surfaced transcripts and leaked recordings seem to have transformed long-standing suspicion into something far more serious.

According to reports referenced by Portfolio, multiple senior Hungarian figures allegedly maintained regular and highly sensitive contact with Russian counterparts, including on EU negotiations, sanctions policy, and Ukraine-related issues.

For many European diplomats, the most alarming part is not simply the content, but the pattern: what now looks less like isolated incidents and more like a long-term structure of information flows and political coordination.

This is why Commission President Ursula von der Leyen is reportedly prepared to raise the issue directly at leaders’ level, elevating it beyond the normal spokesperson or technical Commission channels.

In Brussels, that is interpreted as a sign that the integrity of EU decision-making itself is now seen as potentially compromised.

If Orbán stays: deeper isolation likely

Should Viktor Orbán remain prime minister, diplomats expect the trust crisis to worsen.

In Brussels, another Orbán term would likely be interpreted not as stability, but as the continuation of a governance model many already view as increasingly incompatible with collective EU strategic interests.

Officials quoted by Portfolio say that in such an atmosphere Hungary would be even less likely to be treated as a fully trusted partner on sensitive dossiers, especially those involving defence, sanctions, intelligence-sharing, or Ukraine.

That would likely further reduce Budapest’s room for manoeuvre in major EU negotiations, including financial and defence-related frameworks.

If Tisza wins: no instant honeymoon

A government led by Péter Magyar may be welcomed more positively in tone, but Brussels insiders are warning against expectations of an immediate diplomatic thaw.

Even the most optimistic EU officials reportedly expect months or even years of close monitoring before confidence could be rebuilt. The reason is simple: Brussels increasingly sees the issue as institutional rather than purely political.

A new government would still inherit ministries, diplomatic networks, intelligence structures, and state bodies that many in the EU now believe require serious integrity reviews.

That means even a dramatic political change in Budapest would not automatically unlock full trust, frozen funding, or smooth cooperation.

Instead, diplomats expect a long probation-style period during which Hungary would need to prove that reforms are real, durable, and embedded across the state administration.

EU funds, EPPO and integrity reforms back in focus

One immediate consequence could be a renewed spotlight on Hungary’s anti-corruption and rule-of-law architecture.

Portfolio’s sources suggest Brussels may push for deeper scrutiny of existing watchdog institutions, including whether Hungary’s Integrity Authority is genuinely capable of protecting EU financial interests.

Even joining the European Public Prosecutor’s Office (EPPO) may not be enough on its own. As recent EU reporting has also noted, a new Hungarian government could gain faster access to some frozen funds through EPPO accession, but only if it is accompanied by credible legal and institutional reforms.

The broader message from Brussels is clear: symbolic gestures will not suffice.

What matters now is whether Hungary can demonstrate that its state institutions are trustworthy partners again.

SAFE defence loans may become the first real test

One of the most sensitive post-election questions may concern SAFE, the EU’s new defence loan instrument. Unlike cohesion or recovery funds, SAFE directly supports urgent military procurement, including ammunition, air defence systems, and strategic defence capabilities.

Because of the leaked Russia-related allegations, diplomats are said to be especially cautious about Hungary’s access to this framework.

Portfolio notes that Hungary has proposed a EUR 17.4 billion defence plan against a EUR 16.2 billion loan envelope, yet the Commission has still not issued its assessment.

For Brussels, this may become the first major litmus test of whether Hungary’s next government can begin rebuilding confidence.
