This book provides the first analysis of the EU-UK Trade and Cooperation Agreement (TCA), which was established to ensure mutual respect and preferential trading relationships between the UK (as a non-Member State) and the European Union. In addition to offering a clear and comprehensible overview of the legal and institutional framework under international, European and UK law, it gives detailed guidance to trade in specific sectors. These include: trade in goods, services and capital; digital trade; energy; fisheries; and investment. It also examines broader themes such as sustainability; health security; cybersecurity; and dispute resolution. This is an invaluable tool for all commercial lawyers working on international trade in the EU and in the United Kingdom.
