Labour made big gains in the UK election and has stopped the Tories from having a majority of Parliament.

This advance is due to Corbyn and the anti-austerity Labour manifesto, as well as to the lousy Tory campaign which revealed its shortcomings.

Although Corbyn's Labour didn't win a majority, it achieved an almost record fraction of votes.

Previous Labour leaders were "convinced that if the public saw their true political nature they’d lose that election that they ended up losing anyway."
