Ah, politics: always so inconvenient. Faced with intraparty dissent and horrible polls, Papandreou announced he is going to call a referendum on the debt deal. In the meantime, another PASOK MP resigned, the party's majority in parliament is now down to two MP's, and six members of PASOK's national council called for Papandreou's resignation. And a recent poll shows 60% of Greeks to be against the deal.
According to the database at the Center for Research on Direct Demcracy, Greece has not held a referendum in 37 years. The last time was in 1974, after the collapse of the military Junta, to decide whether Greece would remain a Republic. Indeed it did, 69% to 31%. Turnout was 76%.
Apparently, judging from this Venice Commission document, this is the procedure:
1. Government proposes referendum.
2. A majority of MP's must support a resolution.
3. The President calls the referendum.
And Friday there's a confidence vote in parliament. So we're not quite there yet...
