What the Mayor of London and the London Assembly do

London has one Mayor and 25 Assembly Members – who are elected by you.

This unique form of government was set up in 2000 and, working with London’s councils, central government and many others, it has an important role in many aspects of London life.

The Mayor of London

The Mayor is responsible for making London a better place for everyone who visits, lives or works in the city. The job ranges from developing policies to setting budgets, from overseeing major programmes to championing London around the world – all in line with his or her vision and in the interests of London.

The London Assembly

The London Assembly acts as the eyes and ears of Londoners at City Hall. It holds the Mayor to account by examining his or her strategies, decisions and actions to make sure they are in the public interest. Assembly Members also champion Londoners’ concerns by investigating important issues and pressing for changes to national, Mayoral or local policy.

What they are responsible for

There are many areas of London life that are affected by the work of the Mayor of London and the London Assembly, such as policing, transport, housing, planning and the environment. The Mayor plays a key role by putting together plans and policies and running and funding projects. Before finalising his or her major strategies the Mayor must consult with Londoners and their elected representatives on the London Assembly.

The responsibilities of the Mayor of London and the London Assembly are detailed below and in the individual pages in the menu to the left.

How the London Assembly works

How London government works

The budget

  • The Mayor of London is responsible for a budget of £17bn which is used, among other things, to run transport, police and fire services, build affordable homes and promote London’s economy. Part of the Council Tax levied by London’s councils is set by the Mayor to help fund these services
  • The London Assembly can amend the Mayor’s budget when two-thirds of the 25 Members agree


What is the Mayor not responsible for?

London’s councils, rather than the Mayor, are directly responsible for many of the services Londoners experience day-to-day like council housing, schools, social services, rubbish collection, street cleaning, parking permits, council tax collection and birth, death and marriage certificates. Central government leads on the NHS, welfare and most forms of taxation.
