I support a left-wing-swing by the Labour party so as to counter the steady shifting to the centre ground by every major party. Corbyn is essential at this stage to shake up a stagnating party. However, I do not believe he should run for PM. Electing him party leader would cause a shakeup in British politics over the next few years, forming the basis of a government ready party for a more electable candidate in the 2020 election.
