Polls open in crucial Greece vote

Greeks have begun voting in their second election in six weeks, and arguably their country’s most critical vote in 40 years, with its treasured place within the European Union’s joint currency in the balance.

The political turmoil has unsettled markets across the world, with fears that a vote in favour of parties that have vowed to cancel the country’s international bailout agreements and accompanying austerity measures could see it forced out of the euro.
