Will her running allow for open debate within the opposition of their stance on the NIR etc.
I think the answer to that is very much a 'yes', though perhaps not immediately.
Alan Johnson's response to Pete Wishart (got that right this time) in parliament today suggests that ID/NIR are unlikely to be in the next Labour Manifesto but he did add a qualifier about it being up to the party as a whole.
I think 'not immediately', because quite a lot of people would need to do some significant backpedalling on the issue of how we absolutely desperately needed the things before they can leave it unmentioned.
There's still a few that won't let go, and they might still hang on to the idea, but unless something changes they are likely to be in the minority.
I guess we'll find out by the time of the party conferences, but we've already had some of the leadership hopefuls making hints in the right direction and with any luck that drift will continue.
