“This is a question of whether we remain in the euro zone. This is very clear. It’s clear to everyone” – Papandreou

Ok, here is the itinerary: The ECB is meeting on November 3rd. The G20 is meeting on November 3-4, The Papandreou is attending on the 2nd day. A Eurogroup meeting will follow on November 7th, followed by an EU Ecofin meeting on November 8.
The Troika was meant to disburse the sixth tranche of the first program in the first or second week of November, as Papandreou returns from G20 weaker we may not see this funding pass.
