Introduction To GB RegulationDownload As A PDFThe UK formally departed the European Union at midnight CET on 31st December 2020. The European Union Trade and Cooperation Agreement was finalised on 24 December 2020, setting out the future relationship. It has since been withdrawn and replaced: “The substance of the Agreement has not changed; however, typographical and other errors have been corrected and the Articles have been renumbered from Article 1 – 783.” UK/EU and EAEC: Trade and Cooperation Agreement [TS No.8/2021] - GOV.UK European Chemical Regulation was retained in GB Law at the time of departure, which is reflected in GB legislation. Northern Ireland continues to be governed by European legislation under the terms of the Windsor Framework (formerly the Northern Ireland Protocol).
