In normal peacetime, these elections wouldn't matter a damn. I was chair of the PLP Northern Ireland committee at one point and I don't recall being called on to comment on the peace process at regular intervals. But these are not normal times. PLP committee chairs can now be expected to have wildly differing views from their Shadow Cabinet equivalents — or at least will have, as Corbyn uses his mandate to roll out whatever policy-making process he will inevitably use to stamp his authority upon policy.
