Rows over Eta and racism loom large as Spain holds local elections

Votes will allow the parties to hone their strategies before December's general election

Spain heads to the polls on Sunday to elect 12 regional governments and 8,000 municipal councils in votes that will allow the governing Socialists and the opposition conservatives to gauge their strengths and hone their strategies before December's general election.

Isabel Diaz Ayuso, the rightwing, populist president of the Madrid region, will be aiming to secure an absolute majority for the People's party (PP), while Barcelona's leftwing mayor, Ada Colau, will be hoping to see off challenges from the regional branch of the Socialist party and a centre-right Catalan pro-independence party.
