@douginamug @resl my perception is he was held to an impossible standard with Brexit.
His own personal position was anti-EU (old school Labour left style — look at who took which side in the 70s referendum). But party policy was pro-EU, and as far as I know he consistently stuck to that position. (It’s obviously not the only thing he differed from the party on, even as leader.)
But that wasn’t good enough for some people — even though he was willing to put his own preference aside in favour of the party’s (and rightly so), the fact that he even had that opinion was unacceptable. (Either because Brexit was such a divisive subject and some people were unwilling to hear nuanced views, or because some people would latch onto anything they could find to criticise Corbyn with, or both.)
