As far as I understand there will still be an election on September, 12th. And what do you mean the three bigger left parties? PdA, the socialists and who is the third?

 I assume neither D66 nor the "greens" (what greens surely not groenleft?) can be plausibly a part of a left coalition now after voting for the budget.

Failure of austerity: Isn't between now and the elections a bit short time period to get any results if austerity works? They will discuss July numbers in early September.
