In a report on the potential impact of PR on local government, the think-tank warns that the choice of an electoral system for a mayor would limit the choice of system for the council. 'Electoral reform therefore needs to be considered alongside and not after a decision to move to a mayoral model,' it says.
Other proposals on the government's reform agenda such as annual elections are also incompatible with a system of PR, the report warns.
The think-tank says that although PR will reduce the number of single-party dominated councils it may not, as many hope, make members more responsive to their electorate or increase turnout at the polls.
