The Far-right Vox is projected to become the third-largest party in Spain's parliament after Sunday's national election.
It made its debut in parliament as recently as April, marking the first time a far-right party had won more than one seat since the country's return to democracy in the 1970s.
Founded in 2013 by former members of the mainstream conservative People's Party, Vox is anti-muslim, nationalist, anti-feminist, Eurosceptical, socially conservative, economically liberal, and staunchly pro-Spanish unity.
Vox is aligned with the broader populist movement that has also risen swiftly in other European countries, notably Italy, Austria, Germany, Denmark and France.
On Catalonia: Vox is vehemently anti-secessionist and wants to rewrite the constitution to abolish regional autonomy and parliaments - a theme that has struck a chord after Catalonia's failed independence bid and unrest in the region.
On Franco's legacy: Vox opposed the recent exhumation of Fascist leader Francisco Franco to a lesser grave. Vox's rhetoric talks of a Spanish "rebirth", with party leader Santiago Abascal referencing founders of fascist ideology.
On the economy: Vox's manifesto includes halving the highest income tax rate to 15%, reducing corporate tax, and abolishing wealth and inheritance taxes. It also proposes to partially privatise Spain's pension system.
