If some aspects of the EU sanctions regime have not been addressed explicitly through regulations by 31 December 2020, they would continue as retained EU law under the EU (Withdrawal) Act 2018. The government will directly implement UN sanctions in UK domestic law after the transition period. Foreign Policy and Legal uncertainty It is true that as an EU member, the UK already had the ability to enact autonomous measures like any other member state. So far, the U.K was one of the drivers of the EU sanctions policy. For example, the UK, France and Germany were attempting to keep the 2015 Iranian nuclear deal alive. However, after Brexit without the peer pressure and scrutiny by the other Member States and EU institutions, the post-Brexit sanction regime will mirror the orientation of the UK foreign policy choices; policy choices that still remain unclear or at least closely aligned with Trump's politics.
