During a debate in the European Parliament focused on Bosnia and Herzegovina's progress towards the EU, Slovenian leftist MEP Matjaž Nemec called for condemnation of Marko Perković Thompson's concerts in Široki Brijeg, asserting that they featured symbols connected to the Ustaše regime. This comment reflects not only internal political tensions in Slovenia but also current electoral messages exchanged in the political climate there. Nemec's intervention seemed to carry a weight beyond mere criticism of the concerts, as it intertwined with Slovenian political dynamics.

Thompson's concert in Široki Brijeg reportedly ended without significant incidents, despite prior accusations labeling the event as fascist, which were subsequently withdrawn. Following the criticism, Thompson's team issued a statement clarifying that the concert celebrated family and community while firmly distancing themselves from any fascist or totalitarian ideologies. The event sparked a wider debate about the impact of nationalistic sentiments and the historical legacy of the Ustaše in both Slovenian and Croatian contexts.

This incident underscores the sensitivity of historical narratives in the region, as well as the struggle to address national identity and memory within a European framework. As such, the dialogue surrounding this event serves as a reminder of the complexities in regional interactions and the continued relevance of historical grievances, especially as countries pursue closer ties with the EU.
