Midland local authorities have warned the Government to forget about plans to abolish county and district councils.
The West Midlands Local Government Association said the time was not right for radical change.
The WMLGA executive committee, representing 38 councils, is urging Local Government Minister David Miliband to drop proposals to turn scores of county and district councils into unitary authorities.
Mr Miliband is believed to be considering a comprehensive reorganisation of local government, which could see smaller county councils such as Shropshire and Warwickshire abolished. Some district councils could also be scrapped, with powers transferring to the counties.
WMLGA chairman David Smith, who is the leader of Lichfield District Council, said the additional duties heaped on local authorities by the Government in recent years meant that a period of consolidation was necessary.
Coun Smith (Con) said: "While we welcome any discussions on how local government can operate more effectively, we first need to know what the requirements will be on local government over the next ten years. We need to understand what we have to do, what we are expected to deliver and look at how we can do that more effectively before we begin to look at the structure of local government.
"Local government has already demonstrated its flexibility and responsiveness to the changing requirements of national government."
Coun Smith listed three areas where local authorities were struggling to cope with government directives. These were the Comprehensive Performance Assessment process, which ranks councils, the Gershon agenda for improving performance and efficiency, which seeks savings, and the Lyons Review of local government spending, which will make recommendations about changes to the council tax.
Coun Smith added: "Until central government confirms the future role and funding of local authorities it makes no sense to get distracted by debates around structural changes."
