Voters in Spain's Basque Country cast their ballots in regional elections on Sunday, April 21.
A Basque separatist party with origins in the political wing of the now-defunct armed group ETA could win the elections there for the first time, with potential implications for the shaky national government.
Opinion polls show the left-wing pro-independence EH Bildu with a narrow lead over the moderate right-wing nationalist PNV that has long governed the northern region - one of Spain's, and Europe's, wealthiest.
Both have around 30% of the vote, according to opinion polls, meaning that neither will be able to govern alone and either would have to seek the support of the ruling Socialist Workers' Party (PSOE) of Prime Minister Pedro Sanchez, which has routinely allied with the PNV before.
Last year, Sanchez became the first Spanish premier to negotiate with Bildu, provoking harsh criticism from conservative opponents.
