Gone but not forgotten (yet): Interreg in post-Brexit UK.

Territorial cooperation has a long history in the UK. Numerous stakeholders in the UK have a long-standing and active engagement in the EU's Territorial Cooperation Programmes (also known as ETC and Interreg). Launched in 1990, Interreg is the EU's framework for territorial cooperation, enabling joint actions and policy exchanges between national, regional and local actors from different Member States. Brexit led to the decision on the part of the UK Government not to participate in EU territorial cooperation programmes after 2021, except for the PEACE Plus programme covering Northern Ireland. This article examines what will be lost because of this decision, especially in terms of what, where and what types of organisations are impacted, and what will be 'missed' in terms of the added value associated with territorial cooperation. At a time when cooperation is seen as a key lever to support efforts in addressing major economic, political, social and environmental challenges, and border relations, the article examines what, if anything, is being/can be done to fill the gaps? The article is based on documentary analysis, programme data and engagement with policy, programme and project stakeholders. [ABSTRACT FROM AUTHOR]
