Greece’s prime minister has warned international creditors not to impose humiliating terms on his country as it seeks urgently needed bailout funds.
Alexis Tsipras said negotiations were at a “critical” stage, but that the lenders’ proposals were “not realistic”.
He was briefing parliament amid growing opposition in his leftist Syriza party to the creditors’ proposals.
Earlier Greece delayed Friday’s €300m (£216m) debt repayment to the IMF.
Mr Tsipras described the EU-IMF lenders’ plan as a “bad moment for Europe” and a “bad negotiating trick”.
He accused Greece’s lenders of massively backtracking on measures agreed in recent months, and of failing to see the need for an end to austerity in their latest offer.
A call for debt relief was a key part of the Greek plan.
The lenders’ proposals were put forward when Mr Tsipras met the head of the eurozone’s finance ministers, Jeroen Dijsselbloem, and European Commission President Jean-Claude Juncker in Brussels this week.
Denouncing their offer on Friday, Mr Tsipras said: “The strangulation of a country is a matter of moral order which conflicts with the founding principles of Europe.”
He said the aim of any deal should be “for a solution and not to… humiliate a whole people”.
He said his own proposals were the only “realistic” option.
Many of his own MPs are expected to object to any concessions by Athens.
All four scheduled repayments to the International Monetary Fund (IMF) in June will now be combined into a single payment at the end of the month.
