EU Enlargement Commissioner Marta Kos is facing allegations that she collaborated with the Yugoslav secret police during the 1980s.
The claims were revived by Slovenian Member of the European Parliament Romana Tomc, a vice president of the European People’s Party (EPP), who said she had obtained new evidence suggesting Kos cooperated with Yugoslavia’s intelligence services. Tomc has formally written to the European Commission requesting an investigation into the allegations.
The issue had already surfaced during Kos’s confirmation hearing in the European Parliament in 2024, where she strongly denied any involvement with the secret police. “I was never a collaborator or informant of the secret service of Yugoslavia,” Kos told lawmakers at the time, describing the accusations as “lies” and “disinformation.”
The allegations have returned to the political spotlight ahead of Slovenia’s parliamentary election on March 22th. Slovenia’s right-wing Slovenian Democratic Party—to which Tomc belongs—is currently leading in the polls against the governing left-liberal coalition previously associated with Kos.
A spokesperson for the EPP confirmed that the group has been informed about the latest claims and will examine the matter carefully.
Kos has been a strong supporter of EU enlargement, calling for decisive steps to integrate Ukraine into the European Union by the end of the next EU legislative cycle in 2029.
Her stance seems to disregard widely acknowledged concerns about Ukraine’s readiness and go against her own previous position. Kos herself had previously flagged in a discussion where she noted that Ukraine had not yet fulfilled a single accession criterion.
