Mayor & Assembly

The Greater London Authority (GLA) is made up of the Mayor and the London Assembly. The Mayor is in charge of the GLA, while the 25 Assembly Members hold the Mayor to account on behalf of Londoners and investigate ways of improving the quality of life in the capital.

GLA group

The Mayor has a wide range of responsibilities across London. Some of these are carried out by the Greater London Authority and others by the wider GLA group, which includes:

GLA role

The Mayor’s main priorities cover a range of public services. Some of his priorities are set out in the GLA Act and related legislation, while the Mayor has chosen others like the GLA’s youth and volunteering programmes. 

The GLA Act gives the organisation a lead strategic role in London's:

  • Economy
  • Housing
  • Policing
  • Transport
  • Planning
  • Environment
  • Culture
  • Health improvement

The GLA also manages Parliament Square and Trafalgar Square and leads on London Resilience, which prepares the capital’s response to major emergencies.

Central and local government

Central government and local government represent the other two tiers of London government. The GLA and London boroughs are mostly funded by central government. It also leads on:

  • National Health Service (NHS)
  • Social security
  • Defence
  • Foreign Policy
  • Most forms of taxation

There are 33 local authorities in London, the 32 London boroughs and the City of London Corporation (external website)These are elected directly by the local communities which they serve. In London, their collective views are represented by London Councils (external website). Boroughs lead at a local level on:

  • Education
  • Social services
  • Housing
  • Planning
  • Environment and waste

The London boroughs and City of London Corporation collect council tax from their local residents, part of which is the GLA precept, which helps fund the GLA and wider GLA group’s work.
