Offaly County Council will lose two councillors, following recommendations by a special Boundary Committee today, while Birr, Tullamore and Edenderry Town Councils will all be abolished.
Details of the changes were released today as part of a report published by Minister for the Environment and Local Government Phil Hogan.
The Minister said he has accepted the report in full and will be making the necessary orders to give effect to the changes in due course. The new system will come into effect for the 2014 local elections.
As part of the changes, the number of county councillors in Offaly will be reduced from 21 to 19.
The existing four electoral areas will be changed to three municipal districts.
