Greece crisis: Berlin accuses Tsipras of seeking scapegoats outside own ranks

Criticism of Greek prime minister reinforces view that Germany might refuse to negotiate with Syriza administration on rescue package until after referendum

Berlin has delivered a blistering attack on Greece's beleaguered radical prime minister, Alexis Tsipras, accusing him of lying to his own people and seeking scapegoats for the country's misery everywhere but in his own ranks.

The German government dismissed desperate attempts by Athens to salvage some form of bailout, prompting Tsipras to hit back, accusing the country's creditors of trying to "blackmail" Greek voters with dire warnings that a vote against austerity in this weekend's referendum would be a vote to leave the euro.
