 The City of London has its own "sui generis" form of local government and is divided into wards, which are ancient and very long-standing sub-divisions of the City.The Council of the Isles of Scilly, is also a "sui generis" unitary authority, has five wards, each returning either 2 or (in the case of St Mary's) 13 councillors to the Council of the Isles of Scilly.Civil parishes in England are sometimes divided into wards for elections to the parish council (or town/city council).
