Greater London Authority (GLA)
The Greater London Authority (GLA), known colloquially as City Hall, is the devolved regional governance body of London, with jurisdiction over both the City of London and the ceremonial county of Greater London. It consists of two political branches: the executive Mayoralty (currently led by Sadiq Khan) and the 25-member London Assembly, which serves as a means of checks and balances on the former. Since May 2016, both branches have been under the control of the London Labour Party. The authority was established in 2000, following a local referendum, and derives most of its powers from the Greater London Authority Act 1999 and the Greater London Authority Act 2007.
It is a strategic regional authority, with powers over transport, policing, economic development, and fire and emergency planning. Three functional bodies—Transport for London, the Mayor's Office for Policing and Crime, and the London Fire Commissioner—are responsible for delivery of services in these areas. The planning policies of the Mayor of London are detailed in a statutory London Plan that is regularly updated and published.
The Greater London Authority is mostly funded by direct government grant and it is also a precepting authority, with some money collected with local Council Tax. The GLA is unique in the British devolved and local government system, in terms of structure (it uses a presidential system-esque model), elections and selection of powers. The authority was established to replace a range of joint boards and quangos and provided an elected upper tier of local government in London for the first time since the abolition of the Greater London Council in 1986.
