Some Labour people seem to think that if they explicitly come out as anti-Brexit, they will lose votes, presumably Labour leave voters. I don't know if that is backed up by analysis. But I suppose the leadership think that in the recent election they garnered both Brexit voters (because Labour were saying they would accept the referendum), and also Remain voters (because they figured that May was going for hard Brexit). This is what I meant by ambiguity. I don't know where this goes now, as Starmer seems to be making noises about the single market, and there is generally an anti-hard Brexit atmosphere in Labour circles, except for the weirdos. I see Corbyn as plugging anti-austerity, which probably works quite well. Plus, of course, the Napoleonic line, why interrupt your enemy when they're making a bollocks of things.
