Dave Semple has a post up which I pretty much agree with. I think there is currency in the argument that MPs should nominate who they want, but from the point of view of the left, it is very important to get McDonnell on – and MPs know they can indulge this push for a wider debate if they wish. The fact that there will likely be no ‘left candidate’ is a great shame.

What’s good about Dave’s post however is the deeper reasoning, so it’s worth reading it here.
