Greek debt crisis: Rivals rally as Greek vote looms

The people of Greece will be given their say on the country's bailout crisis, in a crucial referendum on Sunday.

The rival "Yes" and "No" camps have held simultaneous rallies in Athens, and Prime Minister Alexis Tsipras has called on voters to reject "blackmail" and the "sirens of scaremongering" when they vote.

EU leaders have warned that a "No" vote could see Greece leave the Eurozone.
