Voting under way in polarised and undecided Spain

Polls have opened across Spain for the country's third general election in four years. The incumbent prime minister, Pedro Sanchez is set to win the most votes.

Madrid: Polling opened in Spain on Sunday with the country voting in a general election for the third time in four years.

Pedro Sanchez, the incumbent prime minister, is set to win the most votes, but his Socialists seem far from scoring a majority in parliament to form a government on their own.

An uncertain outcome and the likelihood of a far-right party entering parliament are the backdrop for Spain's most polarised national election in decades.
