This article explores how sovereignty fictions have been used to advance different legal, political and economic aims in the articulation of the United Kingdom's future approach to global regulation. By mapping the transformative shifts in sovereignty paradigms, this article highlights the disconnect between the absolutist sovereignty popularised in the UK government's political rhetoric and the concept of regulatory sovereignty that underpins the UK's future trading strategy. To maintain its status as a global leader in regulation and standards-setting, the UK government will need to diffuse power and delegate autonomy through networked orders of public and private actors. These competing sovereignty paradigms are analysed with reference to European Union (EU) law and practice, to highlight the opportunities and challenges for the UK as an independent trade actor. This article concludes by evaluating how sovereignty fictions can disrupt the objectives of the UK's proposed ‘common law’ approach to regulatory governance and discusses the policy interventions that may be required to enable the UK to harness its potential as a regulatory leader.
