The Politics of EU diaspora in the UK post-Brexit: civic organisations' multi-scalar lobbying and mobilisation strategies

Focusing on the3million—a major organisation that was formed after the 2016 Brexit Referendum to represent EU citizens in the UK, this article explores the role of online communication in supporting civic actors’ lobbying and mobilisation strategies at local, national and international levels. Apart from multi-scalar dimensions of these civic organisations’ work and of the way EU citizens themselves engage, we identify different strategies of impact. These are inter-linked and performed in a nonlinear fashion and include: emotionalising; politicising; channelling; contesting. These findings elaborate on the way multinational diaspora formation and mobilisation in the 21st century should be conceptualised, and their importance for stakeholder empowerment. We argue that contextual factors—both in terms of the socio-political capital of the people engaged in mobilisation and the features and dynamics of opportunity structures in a particular country and historical moment—are important in understanding why civic actors emerge, how they mobilise and the way their status and focus of their work transforms over time. The article significantly contributes to research studying the use of digital communications and especially e-newsletters and e-mails by non-state actors for mobilising and lobbying purposes.
