Following the UK’s departure from the EU on 31 January 2020 the UK-EU Withdrawal Act (EUWA) provided for a transition period (which ended on 31st December 2020) during which the UK’s listing regime remained unchanged. From 1st January 2021 the EUWA repealed the European Communities Act 1972 - so ending the supremacy of EU law – while at the same time preserving the existing UK laws which implemented applicable EU law into UK law. Consequently, the current UK listing regime continues to be derived from EU law.
