I will certainly vote for FPTP, there is too much danger of extremists being voted in by default, in my opinion.

Victoria Derbyshire ran a mock election on her Radio 5 programme last week, whereby a group of people voted using both FPTP and AV.  Interestingly, the result in both cases was the same - in that case, a Labour candidate won both., (and in a seat that is currently held by the Tories).  What was interesting was that the first person to lose out under AV was the BNP candidate, whilst the UKIP was the third candidate to be discarded.  In the end, the final two were the Labour and the Green Party candidates with the Tory candidate being the final (4th IIRC) discard.

Interestingly, despite the recounts, the Labour candidate did not get 50% of the 'popular vote' - as some advocates of AV claim will always be the case - but her proportion of the vote rose from 35% to 49%.

I think that Tangnefedd's fear about extremists being allowed in through the back door with Av is an unfounded fear - after all, we use PR for the Welsh Assembly Government elections (as do the Scots for their MSPs), and it is used in the internal elections in most of the main political parties.

I agree that AV isn't proper PR, but it is a step in the right direction, as it tends to provide larger proportions of votes for the final winners.  We know that, apart from one or two constituencies, the extreme parties have very small followings let alone underlying support; I think that we will find that the likes of the BNP and the SWP will suffer the same degree of results under both FPTP and AV systems.
