In the UK, there's a website that shows you the policies from each party running for election, but it doesn't tell you which party they belong to. The idea is that you pick the policy you most agree with in each category and at the end it will tell you which party you agree with the most. When I took it last year, 2/3 of the policies I chose were from centre-left/left wing parties and 1/3 were from centre-right/right wing parties. I've never voted for a right leaning party in a general election (and don't plan to), but over the past decade, I've felt more and more alienated by the direction that left wing politics has been heading in, and it's pushed me closer to the centre, but I'd still consider myself centre-left, just about.
