As the core of devolved powers relate to social policy, identifying the impact of leaving the EU on aspects of social policy is highly significant. This article examines the impact of EU programmes, funding, directives and regulations as delivered in recent years, noting the nature of the participation of the devolved administrations in EU decision making. The post-referendum concerns of the devolved governments and their approaches to Brexit and Brexit negotiations are explained.
