Generate text that refutes this claim: Mayors would raise the profile of the city they represent  Elected mayors would speak on behalf of their communities, raising the profile of their town or city nationally and internationally. This could be particularly valuable when negotiating with businesses, helping to draw valuable investment into their area and overcoming bureaucratic hurdles that typically hinder development. Chambers of commerce in cities that are holding referendums believe a figurehead will provide a focal point for business relations and a single point of contact that champions the city’s interests. [1] In addition, mayors would give local government in general a higher profile after years of increasing centralisation by national government. Acting collectively, and through the change in attitudes their higher media profile would generate, mayors would be able to draw power away from the centre once again and bring it closer to the people.

local government house would directly elect city mayors
Electing a maverick candidate could do the image of a town or city a great deal of harm rather than good. Cities such as Birmingham have already been highly successful at attracting inward investment under the present system of local government. In any case, the major bureaucratic constraints on investment relate to issues of subsidy and tax-breaks, which are outlawed by the EU, and to national taxation and planning policies, set in Whitehall, none of which will be affected by an elected mayor.
