The European Union's transparency watchdog has suspended MCC Brussels, a right-wing think tank with documented ties to former Hungarian Prime Minister Viktor Orbán, from the EU's official Transparency Register—a database that tracks lobbyists and campaign groups operating within EU institutions.

The suspension was confirmed in an email sent by the secretariat of the EU Transparency Register to MCC Brussels, which POLITICO reviewed. The watchdog accused the organization of failing to disclose required financial information, including its sources of funding.

What the Right Is Saying

Critics of the suspension, including some conservative commentators and think tanks aligned with nationalist movements, have raised concerns about what they describe as selective enforcement. They argue that transparency requirements can be weaponized to marginalize organizations that challenge mainstream EU positions. Supporters of MCC Brussels have pointed to its academic mission and the value it brings to policy debates.

What the Left Is Saying

Transparency advocates and progressive lawmakers have largely welcomed the suspension as a necessary enforcement action. Pro-EU groups argue that disclosure requirements exist precisely to ensure that foreign-influenced or opaque organizations cannot operate unchecked within EU policy spaces. They contend that organizations receiving support from figures like Orbán—who has frequently clashed with Brussels over rule-of-law concerns—should face heightened scrutiny.

What the Numbers Show

The EU Transparency Register currently contains entries for approximately 12,000 organizations. The register is voluntary but provides official accreditation for groups seeking access to EU institutions. Organizations suspended from the register face significant barriers to formal engagement with European policymakers. MCC Brussels had been registered as a think tank operating in Brussels since at least 2021.

The Bottom Line

The suspension of MCC Brussels highlights ongoing tensions between EU transparency enforcement and organizations with connections to governments that have faced institutional friction with Brussels, particularly Hungary under Orbán's leadership. The organization has the right to appeal the decision through established EU procedures. What remains unclear is whether MCC Brussels will provide the requested financial disclosures to regain its registered status or challenge the suspension on procedural grounds.
