According to the UK Independence Party website UKIP will try to achieve the following if they gain power at the 2010 general election:

The single member constituency system would be retained, which provides strong representation, and introduce the Alternative Vote for all national and local elections allowing voters to list their candidate preferences. We will oppose measures that allow electoral fraud, and tighten up postal voting criteria.

I would be interested to hear both positive and negative views on UK Independence Party’s Voting Systems policies in the comments below?
