I have thought long and hard about this, and I am sure that Chi will have spent considerably more time tussling with what is the right thing to do. I support her decision: leadership does not come naturally and it is clear that, despite his policies, his great work as an an MP, and having let us believe we could have a socialist Labour Party once again, Jeremy Corbyn does not have the skills and personal qualities to lead or to unite the Party. This is a sad conclusion to reach but unavoidable.
