Almost 4.5 million people will go to the polls today in regional elections in Spain’s turbulent Basque region and in north western Galicia.

A powerful bomb exploded today near the Basque city of Bilbao, killing a policeman in an attack blamed on the separatist group Eta.

Spaniards voted today in local and regional elections following an acrimonious campaign centring on major issues such as terrorism and the Basque conflict.
