Off topic and unfair to single you out Dobba, but I do detest all this narrative bollocks. It's always the other lot that has a narrative, never us. Narratives are what bad people have. We on the other hand can be nuanced now apparently, that works the other way, we're nuanced, but they aren't.
Anyway, sorry about that, to address your point, I don't think Corbyn is a weak leader at all, he's continually strengthened his position within the party, which is what you would expect an effective leader to do. My problem is that I can't trust what it is the party actually wants. Normally I would look at the manifesto to see if I preferred it to the others, but when a manifesto says one thing and the party leader wants another, over such huge topics as brexit and defence, then which do I believe?
