Picture shows ballots in a booth for the regional elections in Cadiz on March 22, 2015. Two parties, ruling Popular Party and Socialist Party (PSOE), have taken turns to govern Spain since the 1980s but now face a rival pair of surging protest movements, radical left wing Podemos and centre right party Cuidadanos, in a dress rehearsal for the national polls due around November.  The vote in Andalusia, one of the poorest parts of Spain, will be a key test ahead of the country's most unpredictable general election in decades.
