No, I don't think they are champions of anyone but themselves, but would labour be any better ? I doubt it. Sure, the poor may get a helping hand, but the one's who will pay for it are the working class, because if he taxes the mega rich and multi nationals, the really mega rich and multinationals won't miss it as much as a worker, who will also have a tax hike and higher prices for goods, as inflation will most likely soar.
What he should have said is anyone who votes for the Conservatives is too thick(though he would still be wrong).
