The Marjan Šarec Party (LMŠ) meanwhile expressed concern with Slovenia's shift in foreign policy triggered by the current government.

Prime Minister Janez Janša is hosting today Hungarian counterpart Viktor Orban, Croatian counterpart Andrej Plenković, Czech Prime Minister Andrej Babiš, Polish Prime Minister Mateusz Morawiecki, Bulgarian counterpart Boyko Borissov and Serbian President Aleksandar Vučić.

Interim SD leader Tanja Fajon said on the occasion that she had always liked coming to the BSF, but this year the event was a kind of a get-together for those who are undermining the EU's basic values, and there was a clear sense of a major shift in Slovenia's foreign policy.

"This could be a cause for concern," said Fajon, pointing out that the government was moving Slovenia away from core European countries.

Jerca Korče of the LMŠ agreed that the shift was clear and she expressed disappointment over the Democrats' (SDS) coalition partners not opposing it.

The Left meanwhile said in a press release that this year's BSF guests were "an elite selection of ultraconservatives and right-wing populists of wider Central Europe".

However, the Visegrad Group is not the source of all evil, highlighted the party, saying that the EU's economic system was fostering right-wing populism by "deepening the gap between the developed centre and the periphery".
