It's perhaps a stark indication of how threatened Greek politicians feel that Anna Diamantopoulou's (minister for education) presence on the future of university education required the attendence of nearly 100 police officer and secret service members.

Despite press announcements that the conference woud be open to the public, the authorities refused entry to anyone without an invitaion, including university students who wished to take part in the discussions about their future.
