Core Cities Group

The Core Cities Group (also Core Cities UK) is a self-selected and self-financed collaborative advocacy group of large regional cities in the United Kingdom outside Greater London and Edinburgh. The group was formed in 1995 and serves as a partnership of eleven city councils: Belfast, Birmingham, Bristol, Cardiff, Glasgow, Leeds, Liverpool, Manchester, Newcastle, Nottingham and Sheffield.

The Core Cities Group has wide-ranging interests, encompassing transport and connectivity, innovation and business support, skills and employment, sustainable communities, culture and creative industries, climate change, finance and industry, and governance. During 2012, the first wave of city deals recognised the eight cities as "the largest and most economically important English cities outside of London". The group in 2020 featured a combined population of over 6 million within eleven of its cities. It has been considered one of the most powerful political lobbying groups in the country.
