Voters are going to the polls in Portugal’s general election, with mainstream moderates trying to keep a populist party at bay.

The election, with 10.8 million registered voters, is set against a backdrop of corruption and economic hardship that have eroded faith in moderate mainstream parties and could push a significant number of voters into the arms of a radical right populist party.
