Leigh, Atherton and Ashton are the areas that see the most significant change if the new political map of Wigan is approved by Parliament.
All but two of the 25 wards will see their boundaries changed in a proposed overhaul of the current makeup of the borough.
Each ward will continue to be served by three councillors - 75 in total -according to the Local Government Boundary Commission, the independent body which has proposed these changes.
This has been done to ensure councillors will represent about the same number of electors, and that ward arrangements will help the council work effectively.
