Spain's far-right Vox surges in wake of Catalan independence protests

Catalan question again dominates campaign ahead of Sunday's general election

Barcelona no longer goes to bed to the smell of smoke, the whoop of sirens or the clattering of helicopters. Three weeks after violent unrest greeted the Spanish supreme court's decision to jail nine Catalan separatist leaders for sedition over their roles in the failed push for regional independence two years ago, the city is slowly returning to something resembling normality.

While sporadic roadblocks set up by protesters have become just another irritation of urban life and rubbish piles up on the streets after most of the bins in central Barcelona were burned on the barricades, the true impact may be more accurately measured on Sunday when Spain holds its fourth general election in as many years. The Catalan question is once again dominating the political debate and could help the far-right Vox party surge into third place, its best-ever result.
