On 26th September, the House of Commons Library published a briefing paper saying that the UK has a new legislative framework for imposing sanctions post-Brexit. What effect would the UK’s departure from the EU have on sanctions policy in the UK and in the EU? What is the broader international outlook? A new 2018 Act provides for creating sanctions regimes independently of the EU, although the sanctions powers are not yet in force, something that will happen by EU exit day. The UK has often pushed for a robust sanctions policy within the EU; after Brexit there is a strong possibility that the EU will become less enthusiastic about sanctions in general, how independent will the UK sanctions regime really be?
