1) Broken duopoly

  • under STV, RLS and AMS
  • smaller parties would gain more representation + opportunity to share in coalition power
  • encourages creation of successful new parties with prospect of winning significant representation quickly
  • i.e Greens, UKIP, SDP (despite 25% of vote in 1987, only won a few seats + joined Liberals in 1988

2) Creation of coalitions

  • no majority so ∴ coalition or minority gov.
  • i.e Scotland, Wales
  • supporters: healthy consensus politics, more continuity, represent wider spectrum of political opinion
  • opposers: unstable gov. without clear electoral mandate

3) Creation of minority gov.

  • no party capable of winning overall majority in HoC
  • supporters: consensus built on indiv. issues, gov. no longer unaccountable + overpowerful
  • opposers: unstable, frequent elections, no continuity
  • i.e Italy (18 post-war elections)

  • more equality among voters
  • accurate reflection of voter opinion
  • less wasted votes
  • more choice
  • potential reduction in public disillusionment with party politics + higher turnouts

5) Indiv. effects

  • STV: multi party system with more than two parties reasonably competing for power + more independents like NI/Eire
  • AMS: less parties being successful + only two parties dominating without ability to form single party gov.
  • RLS: potentially 6+ parties gaining significant number of seats + most unstable
