Most councillors, including most Labour councillors, have no say in council policy or decision making. That is in the hands of only TEN people. So if you don't live in Burngreave, Birley, Park and Arbourthorne, Nether Edge, Walkley, Darnall, Southey or Gleadless Valley YOUR councillor has little say in decision making in Sheffield. The idea of It's Our City is to allow ALL COUNCILLORS to have more say, and to represent their constituents (ie those of us who don't live in that handful of wards, which is most of us) more effectively.

Under a committee system the committees would still be made up of elected councillors - it's just that more of them would be directly involved in decision making, which means that more Sheffielders would be directly represented by their chosen councillors.
