As Greece teeters on the brink of nobody knows quite what the IMF has issued a revealing report on the state of Greece’s finances which appears helpful to the embattled Tsipras government. It thinks Greece will need another 50 billion euros, its existing debts have to be subject to a major haircut as they can never be repaid and it will take twenty years for the Greek economy to recover. This may be seen by Tsipras and the No campaign as a straw in the wind as, let’s face it, everybody is being pretty nasty to them just now, but in truth it is much more powerful. It is a rebuke to Germany.
