Topic - Greater London Authority

The Greater London Authority (GLA), also known as City Hall, is the devolved regional governance body of London, with jurisdiction over both counties of Greater London and the City of 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. - Source: Wikipedia
