The secretary general of the Slovenian Socialists, Dejan Levanič, said that the “self-determination of nations represents the most basic democratic fundamental of the European Union” and pointed out that “every true social democrat therefore stands with Catalans” via his Twitter account. Levanič also endorsed a statement made by the party's second-in-comand, Jan Škoberne, who highlighted that Catalans “don’t need to be afraid” because he “strongly believes” that Slovenia “will be among the first to recognize” the Catalan Republic. “People of Slovenia stand with Catalonia,” added Skoberne.

Answering people’s comments, Škoberne insisted on the fact that “Catalonia has the same right to self-determination” as Slovenia. “Terror from Spanish Government only confirms this thesis,” he stressed. Slovenian socialists have six MP’s in the Parliament and are in the governing coalition. The party is also a part of the Progressive Alliance of Socialists and Democrats (S&D) in the European Parliament, which also includes Catalan Socialists.
