fyi.....only Greek Prime Minister
The guy is a bald-face liar. No one is impeding Greece's right to hold a referendum. Greece could have held it a week (or a month) ago and the EU decision not to extend the June 30 deadline - of which Tsipras's gov't has long been aware - is a clear message that his duplicity is known and rejected. He played out his mendacious cards with the creditors and Greece's EZ partners and is reduced now to trying the same with his Greek constituents.
Watch for Tsipras to suddenly "find" a few billion with which to satisfy the IMF and buy a few days of breathing space from the EZ.
