Do you have any thoughts about this? I don't know UK politics, but I'm reading some commentary saying Corbyn will swing Labour so far to the radical left that they'll not be competitive against the Tories. Even as the Tories are moving to the radical right with even greater austerity.
Mainstream UK politics has become rather homogeneous over the last 20 years. UKIP has provided the only "real" alternative to the main parties, with its right-wing agenda, based seemingly on the basis of “ten things that really annoy people”, with no inkling of implementation method or any costings; a wish list for The Annoyed (not unlike Trump's strategy on your own side of the pond).
The only way Labour can distinguish itself from the Conservatives and the Liberals is to move further to the left, otherwise it risks becoming an irrelevance. It might work and it might not. The Scottish National Party have proved that it can work, having swept the board in Scotland on a left-wing platform at the last general election. There could well be an appetite for a left-wing government by the time the Conservative Party has finished its ongoing "Austerity Britain" project. Given the magnitude of his win, Corbyn now has a huge mandate from all sections of the Labour Party. If he manages to keep it together, who's to say he could not repeat his populist leadership win at a general election?
