In recent years, having opted-out of the single currency and the Schengen area (which allows Europeans to cross borders without passports), the UK has distanced itself from important EU initiatives. Nonetheless, Prime Minister David Cameron surprised everyone by vetoing a new EU treaty on December 9 – a first for the UK since joining the Union – leaving the other 26 member states to press ahead with greater fiscal integration on their own.
近几年来，英国选择退出单一货币和申根协议（允许欧洲人在不用护照的情况下自由地穿越国境），一直与重要的欧盟计划保持着距离。尽管如此，12月9日卡梅伦首相否决欧盟新条约的举动还是令世人震惊，这是英国加入欧盟以来第一次这样做。否决新条约将使剩下26个成员国领先英国一步，走向更深层次的财政一体化。更令人震惊的是，条约谈判是在金融监管的细枝末节上谈崩的。
