The councils say the Boundary Committee, which is conducting the consultation, had received responses from only 0.4% of Norfolk’s population.
The leaders and chief executives of Norfolk’s five district councils will be writing to Archie Gall, Director of the committee, to demand an extension to the public consultation period.
The Boundary Committee’s initial twelve week public consultation period on its proposals to create a single unitary covering the whole of Norfolk and Lowestoft ended last Friday.
Cllr John Fuller, Leader of South Norfolk Council speaking on behalf of the district councils, said: “The government’s Boundary Committee is currently considering proposing a single, mammoth council covering the whole of Norfolk and to abolish all of the local councils in the county.
"But they have canvassed the views of less than half of one percent of the people who live in this county. That’s a disgrace. You cannot make an important decision like this without having talked to people.
"The Boundary Committee must extend the consultation period and start listening to local residents.”
