The project examining the levelling-up of Britain’s regions seeks to help address the problem of profound spatial inequality in the UK by drawing lessons from international success stories of cities that bounced back from decline. The lessons drawn by the team of world leading experts will utilise the government's Levelling Up policy agenda to seize the opportunity to solve what is a fundamental problem. Eight in-depth case studies inform this research. This note summarises some of the emerging insights to inform the debates at the South Yorkshire Economic Summit.
