If Greece leaves the Euro, Cameron should start the British renegotiation all over again

Tonight, it is still not clear how the Greek situation will be resolved. The European Central Bank–which is desperate to avoid being dragged into the politics of this situation–has chosen a middle way on its emergency assistance to Greek banks. It has neither ended it—which would have crashed the whole Greek banking system—nor extended it, which would have enabled the banks to stay open and eased the pressure on the Syriza-led government. Greek banks will definitely be closed tomorrow and probably until the referendum on Sunday.

The next big question is what happens on Tuesday when the bailout programme ends and a payment comes due to the IMF which Athens will not be able to make. It is worth remembering, though, that there is no mechanism for a country leaving the single currency.

If Greece does end up being forced out of or quitting the Euro, which is more likely now than it has ever been, the rest of the European Union will be far too distracted to pay much attention to the British renegotiation.
