The LGA is the national equivalent of London Councils: it represents all the councils in England and Wales, nearly 500 of them in total.
It describes itself as a voluntary lobbying organisation that exists to promote better local government.
It was formed in 1997 from a merger of the three separate organisations that represented metropolitan, district and county councils. When lobbying, the LGA leads on national issues that affect local government, while London Councils concentrates on those that have a particular relevance to London.
