Combined Authority

A combined authority (CA) is a type of local government body introduced in England outside Greater London by the Local Democracy, Economic Development and Construction Act 2009. CAs are created voluntarily and allow a group of local authorities to pool appropriate responsibility and receive certain devolved functions from the central government, creating a form of regional government able to deliver transport and economic policy more effectively over a wider area. In areas where local government is two-tier, both tiers must participate in the combined authority.
