They seem to think that the Greece problem is the only one they face. However if they renege on written agreements to the UK, they may find that Greece is the least of their problems.
No matter how we feel about the EU and the referendum, lying to us and telling us that signed written commitments are "negotiable" on a QMV basis on which we can be voted down; is not a referendum winner.
That written agreement was given in order for the UK to sign into power the ESM which they used to bail out the PIIGS. To now state that it's "political" and can be ignored is more than unacceptable. It calls into question every written agreement made in Brussels.
This will be presented as exactly what it is come referendum time. You can't trust the signed commitment of the EU. They LIE.
