P.R.(4)

So it can be argued that STV produces a "fairer" result than either FPTP or ATV - although you can certainly come up with scenarios where this isn't so, and there is an argument that STV tends to favour "wallpaper" candidates who have no strong views (or at least don't express them) on anything, and are therefore more likely to end up as voters' second preferences. But the main problem with STV is that it needs bigger, multi-member constituencies which some would say dilutes - or even breaks - the link between a voter and his MP. At present, I know who my MP is - whether or not I voted for them - but under STV I could be represented by 3 or 4 MPs covering a far larger area, and it might be more difficult to know who to approach if I felt the need. So there have been various attempts to come up with some sort of hybrid solution which keeps the one-to-one link between the voter and their MP, and this has led to a form of PR known as AMS - the Additional Member System, and we'll look at that next time.
