Labour's position on Brexit is total opposition to the May botched deal. Once the deal is voted down, Labour wants a general election. They may get that by tabling a motion of no confidence in the government. If that fails, I should think that Labour would support a new referendum. If that happens and the electorate votes to remain, that is NOT the Labour Party "betraying brexit." As a member of the party I feel frustrated that Corbyn has not been far more assertive in setting out the party's stance, and that will come back to bite him. But let's not forget that the party in charge of brexit is the Tory party. There are people here who ridicule and dismiss Corbyn, so I find it odd that they are braying for him to reveal his stance, which you'd have thought would be of no interest to them, at least until he gets power. I have a feeling that increasing numbers of one-time leavers are now losing courage and are secretly hoping for no-brexit. If that is achieved they'll be accusing us of betraying brexit, undermining democracy, etc, whilst at the same time breathing a quiet sigh of relief.
