尽管英国继续保留欧盟成员国资格从本质上讲与欧盟一体化并不矛盾（本质上这就是我所提出的两个欧洲合一 ） ， 但创建能够支持永久性多币种联盟的体制将构成极大的政治和法律挑战。
Though Britain’s continued EU membership is not fundamentally incompatible with a more integrated eurozone, creating institutions that can support a permanent multi-currency union – essentially, as I have argued, two Europes in one – will be politically and legally challenging.
