There are six metropolitan counties based on the most heavily urbanised areas, which do not have county councils. In these areas the principal authorities are the councils of the subdivisions, the metropolitan boroughs. Elsewhere, 27 non-metropolitan "shire" counties have a county council and are divided into districts, each with a district council. They are typically, though not always, found in more rural areas. The remaining non-metropolitan counties are of a single district and usually correspond to large towns or sparsely populated counties; they are known as unitary authorities. Greater London has a different system for local government, with 32 London boroughs, plus the City of London covering a small area at the core governed by the City of London Corporation. At the most localised level, much of England is divided into civil parishes with councils; in Greater London only one, Queen's Park, exists after they were abolished in 1965 until legislation allowed their recreation in 2007.
