The really important point from Jeremy Corbyn's "how would you vote in another EU referendum?" interview was his quiet insistence that there was not going to be another EU referendum.
Of course, that was a key part of the prospectus on which he beat Owen Smith, and on which he strengthened Labour's hold on the Leave heartlands. But the message has still never quite got through to some people.
So it bears repetition. There is not going to be another EU referendum. At least, certainly not under Corbyn. And thus, certainly not under Labour. As for the other lot, who knows anymore? Or even cares?
