Europe’s once surging movement of nationalist populists suffered a significant setback in Slovenia on Sunday, in the formerly communist east, on the same day French voters rejected the far-right candidate Marine Le Pen in their presidential election.
In parliamentary elections in Slovenia, a noteworthy test for the appeal of right-wing populism, preliminary results indicated that the prime minister, Janez Jansa, an ardent admirer of former President Donald J. Trump, lost to centrist rivals. Liberal democracy has come under particularly intense pressure in the region over the past decade.
With 95 percent of the vote counted in an election that the opposition called a “referendum on democracy,” results indicated that Mr. Jansa’s Slovenian Democratic Party, competing against 19 rival parties, had won around 24 percent of the vote. That is far behind the 34 percent of its main rival, the centrist Freedom Movement, meaning that Mr. Jansa is highly unlikely to keep his post as prime minister.
The results, showing that no single party won a clear majority, presage a period of political haggling as rival groups try to stitch together a stable coalition in parliament. That should be within reach of the Freedom Movement, led by a political newcomer, Robert Golob, a former energy company executive, with help from the Social Democrats and other smaller parties.
