One of the promises of Brexit was to allow the UK to regain its legislative sovereignty from the EU. However, after Brexit, UK data protection law must remain in line with EU standards in order not to lose the adequacy status that allows personal data to be transferred from the EU. This circumstance generates tensions between the EU, which is committed to preserving its digital sovereignty by ensuring an adequate protection of personal data even beyond its borders, and the UK's ambition to become a champion of the digital economy by adopting an innovative and pro-business legislation in the digital field. The book analyses the latest legal and policy developments in this context, focusing on data protection but also exploring its intersection with other related regulatory areas, such as artificial intelligence and online safety. Renowned international experts contextualise current regulatory trends and policy proposals to understand whether a new UK model in the field of digital regulation is emerging and to what extent this will exacerbate existing tensions between the UK and the EU. The book includes an accessible and detailed analysis of the major judicial decisions, laws, and current bills offering an invaluable guide to academics, practitioners, and policymakers navigating the complex issues of cross-border data protection post-Brexit.
