This is tightrope stuff, but Labour have to avoid giving May a lifeline. If they commit to a second referendum then she will accuse him of helping the EU, and use that to unite her party behind what ever shitty deal she can/might get.
Labour’s focus has to be on a general election until such time that there is a deal to vote on. They’ll then reject that deal because it won’t meet their 6 tests.
Looks like the referendum choice that Corbyn will back is to accept May's deal or to reject it.
Given that the "deal" at this stage is the withdrawal agreement (citizens rights, financial settlement. backstop), and that without it we have no transition then it's no choice - it's between fragile stability (planes still flying etc) or total chaos. Who could vote for chaos?
Anyway, Labour are clearly hoping that if the people vote no-deal then:
a) A GE would be announced
b) The EU would extend A50 to allow for the GE
c) Corbyn would win said GE
d) And could then cherry-pick the single market aspects he wants in a way that the EU refused when it was the Tories asking
