That looks a bit pointlessly nuanced, and time-wastey, and weak. "I'm not talking to you until you put the matches and and petrol down" sounds better to me than "Yes I know she's waving that petrol can around but I'll just go and see what she wants". Her offer is really not worth dignifying, and whether he points that out now or tomorrow or next week after she's run the clock down further, the Sensibles are still going to be united in praising her surprising last minute flexibility and Corbyn's failure to put the country first. There really is no point playing to that crowd, and no point pretending any longer that there's room for any kind of consensus here. The Tories have spent the last two and a half years spelling it out for us: the only way through this is through their charred remains. The Conservative PArty want to set something on fire, and it's either going to be themselves or the country. They are close to doing the former. All we can do is keep the pressure on until they actually do it. Why pretend we're dealing with rational people here?
