'You are embarrassing': Tony Abbott slapped down over Brexit claim, page-77

Interesting what your idea of sovereignty is and why you think nation have lost theirs.

All countries in the EU still have their sovereignty, being in the EU just means they operate as a common market so it's much easier to trade with each other and cross borders

Sovereignty is more than anything else a matter of legitimacy [...that] requires reciprocal recognition. Sovereignty is a hypothetical trade, in which two potentially conflicting sides, respecting de facto realities of power, exchange such recognitions as their least costly strategy.
