The Oxi or No vote handsomely won this referendum  61 – 39 rejecting the European bailout of Greece and the attached preconditions.

The question itself was rather convoluted “Should the agreement plan submitted by the European Commission, the European Central Bank and the International Monetary Fund to the Eurogroup of 25 June 2015, and comprised of two parts which make up their joint proposal, be accepted?”  This is the only plebiscite of its kind to ever take place in Greece.  All previous votes have related to the constitutional questions of how Greece should be governed.  A similar referendum to this one was called in 2011 but subsequently cancelled after pressure from Eurozone members.

The ballot itself is relatively copiable.  There doesnt appeat to be any safety feature on it at all including serial numbers, watermarks or seals.  The size is the only distinguishable feature.
