It is very interesting to see that when people are asked to vote on policies the Green party come out best - see http://voteforpolicies.org.uk/

Greens are still at 28% with the largest share of the vote with over 137,000 people having voted already. Do have a go! The other website that might be of interest is the BBC's site which compares party policies. You can go to it here.
