ABSTRACT
This chapter establishes a comprehensive theoretical framework for multi-agency collaboration in the planning and management of large-scale events, drawing upon academic and professional literature across diverse domains. It examines key concepts such as threat and risk management, information and intelligence sharing, leadership and decision-making theories and the role of relational sociology in fostering communication and trust. The chapter contextualises these themes through the case study of ESC23, offering insights into the formation, functioning, and challenges faced by multi-agency groups responsible for event safety and security. It considers how threats and risks are identified, assessed, and mitigated and highlights the importance of collaborative approaches in addressing uncertainties. By integrating theoretical perspectives with practical experiences, this chapter provides a foundation for evaluating the effectiveness of multi-agency working at large events and informs recommendations for future large event management.
