Greece - The polls have opened in Greece for crucial elections which could determine the country's future in the eurozone.
The main contenders, the right-wing New Democracy and left-wing Syriza, are at odds over whether broadly to stick with the tough EU bailout deal, or reject it and boost social spending.
Opinion polls are banned for two weeks before voting but unofficial polls say the result is too close to call.
EU leaders say if Greece rejects the bailout, it may have to leave the euro.
The poll, the second in six weeks, was called after a vote on 6 May proved inconclusive.
Sunday's vote is being watched around the world, amid fears that a Greek exit from the euro could spread contagion to other eurozone members and send turmoil throughout the global economy.
Tough austerity measures were attached to the two international bailouts awarded to Greece, an initial package worth 110bn euros (£89bn; $138bn) in 2010, then a follow-up last year worth 130bn euros.
