When the local councils are, in many cases, not the same party as the seat in Westminster (ie. My local council is Lib-Dem, but the MP is Conservative) they obviously have no real control over what happens in constituencies. It seems to me they become, after being elected, simply a device to be used by their own party to add weight to the cabinet's decisions and completely pointless to those that elected them.
Why can't local representatives at general election be the same as our local representatives all the time ? I cannot see how a Westminster MP is accountable for anything otherwise.
