The ultra-conservative and anti-immigration Vox has stormed into the Andalucian assembly in Sunday’s regional election, marking the first time a far-Right party has achieved parliamentary representation on any level in Spain’s recent history as a democracy.

The party that favours the end of autonomy in Catalonia and the expulsion of all immigrants who entered Spain illegally won 12 out of 109 seats in Andalucia’s parliament with 11 per cent of the vote.

“Vox was the party that led the political debate,” said the party’s secretary general, Javier Ortega.

“We put on the table the need to control our borders and end illegal immigration, end abusive levels of taxation and the need to put an end to ideological laws relating to gender.”

Despite running out narrow winner in the region it has ruled continuously for 36 years, the PSOE Socialist party of Spanish Prime Minister Pedro Sánchez suffered a hugely disappointing result in Andalucia. The party’s all-time low of 28 per cent and 33 seats mean it will not be able to govern with a majority, even with the support of the Left-wing coalition Adelante Andalucia, which includes Podemos.

Spain’s main conservative opposition force, the Popular Party (PP), also lost ground, sliding six percentage points to just under 21 per cent, while the liberal Ciudadanos was the night’s only winner among the established parties, doubling its share to 18 per cent.
