Spain votes in fourth election in 4 years

Spain is voting in its fourth general election in as many years amid heightened tensions over the separatist push in Catalonia that has fuelled a surge in support for upstart far-right party Vox. The repeat polls were called after Prime Minister Pedro Sanchez failed to secure support from other parties following an inconclusive election in April which saw his Socialist party win the most votes, but no working majority in parliament.
