Leicester's Labour mayor Sir Peter Soulsby plans to expand his city's boundaries have been opposed by neighbouring district councils and Rutland CC.
District councils have rejected the expansion scheme, instead proposing a three unitary plan.
The Labour leader of Melton BC, Pip Allnatt, said: ‘We understand the city council's ambition for growth, but the leaders believe that by delivering devolution quickly and collaboratively, we can support growth and deliver economic improvements across Leicester, Leicestershire and Rutland.'
Sir Peter said: ‘I am convinced that any realistic option for local government reorganisation in Leicester, Leicestershire and Rutland must address the historic accident of our city's boundaries.
‘Unlike other cities, Leicester's boundaries have not changed in more than 100 years and no longer reflect the reality of the wider urban area and how people live their lives.
‘An expanded city is key to unlocking devolution and boosting local economic growth, as well as delivering more efficient and cost-effective council services across the wider area.'
