It would be a) short sighted and b) a failure in duty for a ward councillor not to let the parish councils in the ward they represent be fully informed of what matters at county level affects the parish. The best way for politicians to stay in power is for them to be in the public eye as much as possible via interaction with the parish council. Championing and seeking solutions to problems of the PC with county level is again, I would view as a necessary duty of a ward councillor.
