I've only just come across this excellent piece by the wonderful Austrian investigative journalist, Jane Burgermeister:
It's interesting to read with the benefit of hind-sight, given the swiftness with which the 'EU' moved to depose Papandreau after this referendum idea, and who they replaced him with (see this blog). Now same is happening to Italy, etc, etc. Serious stuff.
I'll be looking out for Jane's next piece with interest.
