Spain and the populist radical right Will Vox become a permanent feature of the Spanish party system?

Vox won the third largest share of the vote in Spain’s general election in November.

Lisa Zanotti and José Rama write that while political resentment and the Catalan independence issue created fertile ground for Vox, the party may find its future growth limited by the resilience of the left-right political cleavage in Spanish politics.
