The Greater London Authority (GLA) is the top-tier administrative body for Greater London, England. It consists of a directly elected executive Mayor of London, currently Boris Johnson, and an elected 25-member London Assembly with scrutiny powers. 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 London Fire and Emergency Planning Authority — 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 local government system, in terms of structure, 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.
City Hall is the headquarters of the Greater London Authority (GLA) which comprises the Mayor of London and the London Assembly. It is located in Southwark, on the south bank of the River Thames near Tower Bridge. It was designed by Norman Foster and opened in July 2002, two years after the Greater London Authority was created.
