In times of fast-paced and unprecedented change, places that stand still fall behind. The response to unprecedented change and challenges must be characterised by action and delivery, which cannot just be led by national governments. When a large part of the UK's productivity struggles is down to significant regional disparities in productivity growth, a one-size-fits-all approach to policy-making cannot be an option. City leaders know their area and the potential of their area better than any London-based Minister or civil servant. Successful cities will be the foundation for a thriving United Kingdom in the post-Brexit era.

In terms of potential, look no further than the UK's mid-sized cities. That is why we as the 24 cities in the Key Cities Group, a cross-party alliance of city leaders, are launching our latest report, Cities in Action [link/reference].
