 These changes would see the existing county council and district councils abolished and two new unitary authorities created in their place.One authority would consist of the existing districts of Daventry, Northampton and South Northamptonshire and the other authority would consist of Corby, East Northamptonshire, Kettering and Wellingborough districts.Unitary authorities combine the powers and functions that are normally delivered separately by the councils of non-metropolitan counties and non-metropolitan districts.
