# Cornwall Council elections

Cornwall Council in England, UK, was established in 2009 and is elected every four years. From 1973 to 2005 elections were for Cornwall County Council, with the first election for the new unitary Cornwall Council held in June 2009. This election saw 123 members elected, replacing the previous 82 councillors on Cornwall County Council and the 249 on the six district and borough councils (Caradon, Carrick, Kerrier, North Cornwall, Penwith, and Restormel). In June 2013 the Local Government Boundary Commission for England announced a public consultation on its proposal that Cornwall Council should have 87 councillors in future.
