“Why did the Greek government call for a Referendum in the first place?
It looks like it was an escalation of a negotiating strategy that, in retrospect, has gone very badly wrong.”
It really has been an odd strategy and bizarre form of brinkmanship, which as you say has backfired on all levels.
From what I make out, although a high level proposal has been agreed, it's far from a done deal and there are still elements that could scupper it when they through all the details.
Not a good time to be a business owner. VAT up, Corp Tax up, luxury tax on nice motors in case you did make a healthy profit. As U turns go, this has to be one of the most spectacular.
I think this Greek tragedy still has a long way to go, and no doubt will turn up a few more unexpected surprises. But it looks like they will cling on to the Euro by their fingernails, even if the Germans are stamping on their hands
