The UK’s decision to leave the European Union (EU) has presented innumerable challenges for both the leaving state and the EU. In these unchartered waters, the future of UK involvement in EU policies is very much in doubt. The Common Foreign and Security Policy (CFSP) has not been at the forefront of the debates about Brexit, despite the increasing focus on the EU’s global role, and the UK’s own vision of a ‘Global Britain’. The purpose of this article is to consider the past, present, and future role played by the UK in the CFSP since its inception in the Treaty on European Union. This necessitates consideration of how the CFSP might develop in the future and fulfil the goals of the recent Global Strategy. The article explores the UK’s constant opposition to greater integration in EU foreign policy and how it has purported to distance itself from the CFSP machinery. This can be contrasted with the UK’s apparent post-referendum enthusiasm for pursuing shared foreign policy goals. The future direction of the CFSP may not be affected to a significant degree by the UK’s departure. However, the CFSP will not necessarily become more integrated after Brexit. To achieve this, greater commitment will need to be shown by the EU27 to the aims of the CFSP, and other Member States will no longer be able to count on the UK as the lead voice of opposition or ‘brake’ on integration. If there is a continued desire for the UK to be involved in the CFSP, finding an acceptable model for cooperation is likely to prove a substantial, long-term challenge.

英国与欧盟共同的外交与安全政策：从脱欧前的“尴尬伙伴”到脱欧后的“未来伙伴关系”？

英国退出欧盟的决定给离开欧盟和欧盟都带来了无数挑战。在这些未知的水域中，英国参与欧盟政策的未来充满了疑问。尽管越来越关注欧盟的全球角色以及英国对“全球英国”的愿景，但共同外交与安全政策（CFSP）并未一直处于有关英国退欧的辩论的最前沿。本文的目的是考虑自《欧盟条约》生效以来，英国在CFSP中扮演的过去，现在和将来的角色。因此，有必要考虑CFSP将来如何发展并实现最新全球战略的目标。本文探讨了英国一贯反对在欧盟外交政策中进行更大程度的整合，以及英国如何声称自己与CFSP机制保持距离。这与英国明显的全民公决后追求共同外交政策目标的热情形成了鲜明对比。英国的离任可能不会在很大程度上影响CFSP的未来发展方向。但是，脱欧后，CFSP不一定会变得更加一体化。为了实现这一目标，欧盟27国将需要对CFSP的目标做出更大的承诺，其他成员国将不再能够指望英国成为反对派或整合的“刹车”的主要声音。如果英国一直希望参与CFSP，那么寻找一种可接受的合作模式可能会证明是一个长期的重大挑战。
