Unlike the fully single-member system in place since 1988, STV groups all legislative seats regionally into multiple-member electoral districts. This is done so that seats in the region can be allocated in a way that reflects the distribution of votes among the electorate. For example, Richmond and Delta's five existing constituencies would be combined into one electoral district which would produce five winners, proportional to the votes in the multi-member district. It is very unlikely that all would be from the same party, in contrast to the situation in the 1996 election, when all five of these seats were won by the same political party.
