Resurgence of Historical Collaboration Claims

EU Enlargement Commissioner Marta Kos is navigating a new wave of scrutiny regarding her past, following assertions that she operated as a collaborator for the Yugoslav secret police during the 1980s. While Kos vehemently denied similar allegations during her 2024 confirmation hearing—labeling them as "lies" and "disinformation"—fresh evidence has been presented to the European Commission. The claims were brought forward by Slovenian MEP Romana Tomc, a vice president of the center-right European People’s Party (EPP), who maintains that documented proof contradicts the commissioner's previous testimony.

Documentation and Institutional Response

At the European Parliament in Strasbourg, Tomc introduced research by author Igor Omerza, citing specific documents that allegedly link Kos to the former Yugoslav spy agency. The EPP has officially noted these revelations, suggesting that the responsibility now lies with the commissioner to address the specific findings. In contrast, European Commission officials have defended the appointment, stating that Kos underwent an exhaustive vetting process prior to being approved alongside the rest of the 27 commissioners. Supporters close to Kos’s office suggest the timing of these claims is strategically aligned with upcoming political contests in her home country.

Political Context in Slovenia

The timing of these allegations coincides with Slovenia’s national elections scheduled for March 22. The domestic political landscape is currently divided between a left-liberal coalition, with which Kos was previously associated, and the right-wing Slovenian Democratic Party, which is currently leading in opinion polls. MEP Romana Tomc belongs to the latter, leading some observers to characterize the resurfaced claims as a move to gain leverage in the Slovenian electoral cycle. The outcome of the national vote could further impact the political standing of Slovenian officials within the broader European administration.
