Sorry Ponty, but they will only form the next government due to our awful FPTP voting system. Only one of two parties can get elected with this system and as more people want rid of the Tories than want to keep them by default Labour will form the next government. Other than doing something really stupid policy wise they cannot lose... the fact that they are likely to be barely any better than the Tories is of no matter... and whether they are closer to Thatcherism than the Tories is an irrelevance. People are voting for them as they don't want the Tories not because they want Labour or their policies.The current Labour Party is closer to the ‘old school’ tory party than the current tory party. Which is why they will form the next govt.
My personal vote will be going to the Greens as quite aside from anything else I could never vote for parties who actively support and encourage mass murder by a sovereign state. The fact that the rest of their policies and beliefs are also hugely weighted towards politics I despise helps I guess. I used to be a Labour Party member and, like my friend mentioned above with the Tories, I find the current Labour Party unrecognisable and abhorrent.
