Martin Kettle in yesterday's Guardian listed the objectives the Corbyn faction are working on in the Labour Party.
"The left faction around Corbyn is focused not so much on new politics or new ideas but simply on taking control of the party machinery. This is an entirely logical approach because, until that is achieved, it is harder to change policy or commitments. The left’s priorities – and they are certainly the priorities of the Leninists Corbyn has brought in – are therefore to make procedural changes. Altering the rules for electing the leader to reduce the influence of MPs; strengthening the grip of the annual conference over policymaking; boosting the national executive at the expense of the shadow cabinet; clearing out opponents in the upper reaches of the party organisation; and, ultimately, deselecting centrist MPs and getting more leftwing, union-endorsed candidates in safe seats."
So now we know what they are up to.
