Graffiti of one particular word is smothering Greece

Greece is set to vote in the bailout referendum on Sunday July 5, and the outcome could lead to Greece leaving the euro.

If Greeks vote "No" - "OXI" in Greek - that means they reject the demands of the country's European creditors. It will also be a rejection of a bailout offer that may not even be on offer any more, considering Greece has since defaulted on its payments and the deadline for that batch of negotiations expired.

If Greeks vote "Yes" - "NAI" in Greek - it means citizens accept the terms of the bailout deal that were tabled prior to June 30, and it is then likely that Greece will stay in the Euro and work through new terms of the bailout programme.

My colleague Mike Bird, who is in Athens this week, reported this morning that two of the latest polls show that both the "Yes" and the "No" camp are neck-and-neck.

Meanwhile, citizens are getting more and more vocal about how they are going to vote. According to a number of picture agencies, some of the most populated areas are now being smattered with referendum related graffiti.

Notably, "OXI" - "No" - is the most prevalent word daubed in red across Athens. Here is a prominent symbol on the Bank of Greece:

And even if official posters are up from the two sides of the campaign - "OXI" or "No" - is being spray painted over the top. Here, according to Getty picture agency, is a "Yes" poster on a bus stop defaced with "No":

Here is how overwhelming the "OXI" vote is advertised:

Greece's ATM locations are probably the most densely populated areas at the moment. Queues are getting crazy as the country's cash withdrawal restrictions continue.

So it is no surprise that many ATMs are daubed with graffiti and, again, mainly with "OXI" spray paint, according to Reuters pictures:

No flat surface is safe from it. Here, Getty took a picture outside the Athens Academy building with more "OXI" graffiti:

All concrete structures seem to emblazon the "No" sign in Athens:
