It's no great surprise why the support is as it is.The two main parties would be unlikely to support it as it means they will both end up with fewer MPs, and winning an outright majority would become very unlikely.The other parties all want it because they would get more MPs.2011 was purely on the AV system which comes with its own set of quirks and unfairness (you can mathematically prove that no voting system can be truly fair if there are more than three or more parties[1], but some are better than others). Of course, if the question had been "Shall we keep FPTP or move to a form of proportional representation?" and the latter had won (with a small majority) the Government would probably still be arguing about what type of PR we should have.As with most referendums, it's best repeated at steady intervals to gauge how public perception is changing over time (countries who do Referendums more often, like Switzerland, do this all the time) along with proper minimum requirements (i.e. a supermajority of 2/3 of the votes required for change, or 75% of the electorate voting) rather than taking a single vote from an mostly ill-informed public and then using it to enact their own private agendas and political gamesmanship in order to (temporarily) grab power.1. https://en.wikipedia.org/wiki/Arrow%27s_impossibility_theorem
