Had been looking for a map that showed what multi-member constituencies might actually look like under proportional representation (STV). Here is one.
They're bigger than the current constituencies, but each constituency would have more MPs, so the effect would be the same. And the MPs would be competing between themselves to help constituents (as councillors do now) so it would improve things.
What is there to object to about this sort of system? (the Lib Dems' preferred one?)
