Former cabinet minister Liam Byrne is to publish a paper setting out his proposals for the powers a metro mayor could weild.
Mr Byrne (Lab Hodge Hill) had hoped to stand for the post of Birmingham mayor if city voters had backed the idea of a directly-elected city leader in the 2012 election.
In the event, voters rejected a mayor by 58 per cent to 42 per cent, but supporters of a mayor argue this was partly because it was unclear what powers a mayor would have.
Mr Byrne said: “I was delighted to see Manchester’s metro-mayor proposal get the green light.
"As Chief Secretary to the Treasury in the last government, I worked hard to accelerate the devolution of powers to Manchester and its neighbours – and the model Manchester has designed ensures strong accountability of any new mayor to local government leaders.
"In effect, the mayor is a member of a Cabinet of leaders drawn from the Manchester metro-area. That is a good idea as it keeps the mayor’s feet on the ground.
"A metro-mayor in the West Midlands would make a big difference.”
His proposed metro mayor would have responsibility for:
* Economic development, including chairing the Local Enterprise Partnership
* Skills and education, including appointing schools commissioners and having some control over the schools curriculum
* Chairing a new transport authority
* Replacing the Police and Crime Commissioner to scrutinise the work of police forces
* A role co-ordinating health and social care
* Taking over the powers of the Arts Council in their region
* Co-ordinating public procurement contracts to ensure that as much as possible goes to firms creating local jobs.
