Increasing workloads mean there should be no change in the number of councillors representing Telford & Wrekin, it has been recommended.
Tory opposition councillors have repeatedly called for the number to be cut from 54 to 40.
But at a meeting of Telford & Wrekin Council they were out-voted.
The meeting agreed that the council should now put the case for a 54-member council to the Local Government Boundary Commission for England, which is reviewing the ward structure of Telford & Wrekin.
Councillor Rob Sloan, chairman of the council’s boundary review committee, said all the information had been looked at, including the results of a workload survey among councillors.
He said: “We have come down to the existing number of 54 councillors but accept each councillor will have a growing number of voters to look after because of the growing nature of the borough. This is just a vote on the number we give to the commission.”
Conservative leader Andrew Eade said: “We have looked at a different model and compared that to the way we did things before and we think there is a compelling case for reducing the number of councillors down to 40.
“We will be making a separate submission to the Boundary Commission to consider the options.”
Labour Councillor Angela McClements said she had originally thought a reduction was a good idea but had changed her mind because of their increasing workload.
