Contributor(s): Yiannis Boutaris | Amidst the economic crisis in Greece, something unusual emerged in Thessaloniki, the idiosyncratic “co-Capital” of the country.

In this lecture, the Mayor of Thessaloniki will talk about the challenges of administrative modernisation and the necessary institutional changes Greece needs to accomplish at the level of local administration so as to accommodate the principle of subsidiarity.
