Depending on where I am in the country, whatever the left-wing alternative is in my constituency. Probably Green or Respect, but it may be a smaller party or an independent. I won't vote for Labour, even to stop the Tories getting in. I just can't do it....
Seems funny that this question was asked by someone who cant vote yet. Because I don't pay attention to these things but what I can say is that I'm not voting for labour! Even if I still dont know what 'the counciler of the exchequer' is. I got my political understanding from Dead Ringers though, so don't listen to me!
