Well, that's going to do interesting things to the Euro. Greece has overwhelmingly voted to reject the austerity package that goes with the bailout they want from the ECB, which they desperately need to repay the IMF and the previous bailout from the ECB.
I can't help but think it all went a bit like this...
"I'm calling your bluff! You're not really going to withhold the loan"
"No, I'm calling your bluff first! You're not really going to reject austerity"
"I'm not bluffing!"
"I'm not bluffing either!"
