This section examines the external relations implications of the UK’s withdrawal from the EU. Understanding the impact of Brexit on the EU’s international agreements and the UK’s legal status in relation to these agreements, once it leaves the EU, is of particular salience as any final arrangement made with the UK will act as a precedent and will thus have significant implications for any future Member State withdrawal from the EU. From the EU’s perspective, the main concern is the impact of Brexit on the EU’s relationship with third countries that are parties to its international agreements. From the UK’s perspective, the UK is bound by all of them even though it is not a party to all of the EU’s international agreements, as they form an integral part of EU law. The paper intends to examine what the possible scenarios might be in a post-Brexit scenario.
