I've just re-read your opening post again, Barden of England. Couple of points:

1) Your thread-title is "Bring back democracy..." The implication is that the UK once had democracy but has it no longer. Comments?

2) I don't think that the way we elect our representatives is at fault -- the problem is with the representatives we elect. Sure, you can argue that this or that PR method would be "better" or that the Lords should be elected, but nothing will improve things until we have MPs of integrity rather than those seeking to be first at the trough.
