As Cameron himself stated after a recent visit to Iceland, the Norwegian option of engaging in free trade with the EU as a non-member is far from ideal. Norway, like Switzerland, still has to abide by EU single-market rules, without having any say in formulating them.
事实上，现实可能远非如此理想。正如卡梅伦本人最近出访冰岛后所指出的那样，挪威以非成员国身份与欧盟自由贸易的条件远非那么理想。挪威像瑞士一样仍需遵守欧盟单一市场规则，但却对规则的制定没有发言权。挪威还需支付大量资金用于欧盟预算，同时必须接受人员（包括难民在内）的跨境自由流动。
