THE single transferrable vote (STV) voting system used in Scottish local elections is more rigorously proportional than the additional member system used in Holyrood elections.
It is a system designed to militate against a local authority being controlled by a single party which has not received an absolute majority of votes, such as we saw in Glasgow during the 1980s and 1990s when the Labour party often took all but a handful of council seats despite the other parties winning a significant percentage share of votes cast.
