The people behind 'Who should you vote for' have put together a quiz about electoral systems. Here are my results:
Key: FPPTP = First Past the Post; AMS = Additional Member System; SYV = Single Transferable Vote; JAV+ = Jenkins Alternate Vote Plus; PLS = Party List System; CC = Cellular Constituencies. For explanations of these systems, please read the electoral reform FAQ
You should support: Single Transferable Vote (STV).
STV requires larger constituencies than is currently the case, each electing between 3 and 5 MPs - with parties able to field more than one candidate in a constituency. Voters rank the candidates in order of preference with candidates being elected through a combination of first preference and weighted second/third/fourth etc preference votes. The system delivers a more proportional result, but is complex and still biases against smaller parties and is more likely to deliver multi-party coalition governments.
