"the definition set out in Article One of the1933 Montevideo Convention on the Rights and Duties of States: “The state as a person of international law should possess the following qualifications: (a) a permanent population; (b) a defined territory; (c) government; and (d) capacity to enter into relations with the other states.”

Until yesterday, the EU qualified on grounds (a), (b) and (c). Now it has ticked the final box. Under the Lisbon Treaty, which came into force today, it acquires “legal personality”, which gives it the right to sign accords and treat with other states. Nor is this right simply theoretical: the EU now has a foreign minister, a diplomatic corps (the European External Action Service) and 160 overseas embassies."
