Greater London Authority

Jul 20

We work to make London the best big city in the world.

The Mayor runs important services in London like policing, fire and transport, with an annual budget of £17bn. The London Assembly holds the Mayor to account on behalf of Londoners. It regularly questions the Mayor and investigates important issues in London.

Together, we are the Greater London Authority. Based at City Hall, more than 800 staff are employed to support the Mayor and Assembly in their roles.
