An order to postpone elections in Daventry and Northamptonshire has been made to Parliament by the local government secretary.
James Brokenshire, acting under the Local Government Act 2000, has delayed all district and parish elections in Northamptonshire due to be held in May 2019.
Daventry District Council was scheduled to hold elections for one-third of its seats, along with elections for 20 parish councils.
District councillors that were due for re-election in spring will continue their position the extra year and parish councils will instead have their elections in May 2020.
Councillor Chris Millar, leader of Daventry District Council said: “Postponing next spring’s elections in Northamptonshire is a sensible move by the Government in the light of the continuing developments towards creating two new unitary authorities by May 2020.
“This will not only avoid any confusion and unnecessary election costs for our taxpayers but enable us to focus our minds on preparing for changes ahead of us in Northamptonshire."
The order states that changes will come into effect on January 14, 2019, and councillors will continue in their position until the postponed elections in May 2020.
