The party of Prime Minister Pedro Sanchez — Spanish Socialist Workers' Party — was set to lose control of southern Andalusia, which it has governed for over three decades, after Vox party took a surprise 12 seats in a regional election on Sunday, handing a majority to right-wing parties in Spain's most populous region, AFP reported.
It was Sanchez's first electoral test since taking office in June after winning a vote of no-confidence against the conservative Popular Party (PP) government of Mariano Rajoy over a corruption scandal.
Top-selling daily El Pais called the results an "earthquake" which have changed the "national political panorama".
The vote kicks off a series of polls with municipal, regional and European elections slated for May, and an early general election widely expected next year.
Vox, which takes a hard line against illegal immigration and Catalan separatism, is the first far-right party to win representation in a regional parliament in Spain since the country returned to democracy following the death of longtime dictator Francisco Franco in 1975.
With its 12 lawmakers, Vox could now play a kingmaker role in the formation of a governing coalition in Andalusia.
Revival of Spanish nationalism
Sanchez, who heads a minority government that has struggled to garner opposition party support to pass its draft 2019 budget, vowed to defend democracy.
"The results in Andalusia strengthen our commitment to defend the constitution and democracy from fear," he said in a Twitter message on Monday in his first reaction to the poll results.
Fernando Vallespin, a political scientist at the Autonomous University of Madrid, said Spain had "ceased to be the exception in Europe", where far-right parties have already made gains in countries like Italy where they now govern.
But unlike other European nations where the rise of far-right parties has been fueled by anti-immigrant and anti-EU platforms, Vox owes its gains largely to its fierce defense of Spanish unity, he told AFP.
The election in Andalusia was first outside Catalonia since last year's failed independence push and it "has had the effect that many feared: the revival of an also extreme Spanish nationalism," Vallespin said.
Vox has called for independence parties to be banned and wants to centralize power by putting an end to regional governments.
