This is a critical time for the future of the European Union and the U.K’s relationship with it. At this year’s European parliamentary elections and beyond it is vital that progressives offer a genuine alternative based on the principles of environmentalism and social justice. This short paper sets out some of the ideas that could form the basis of that alternative. We hope that this vision and these ideas can be pursue collaboratively by people in different left, green, and regionalist political parties, as well as activists, trade unionists and others outside of party politics.
