At the beginning of November 2018, things are changing fast: it seems that parties are now willing to compromise a bit.
From what we can understand from the rumors spilling from Downing Street (caveat emptor, as everything can change in 24h), post Brexit the UK will stop freedom of movement and (possibly) ECJ jurisdiction.
By giving up voice, vote and veto (and still paying considerable amount to the EU budget), the UK is allowed a sort of (very painful and expensive) cherry-picking (ie. it will still be — fully as a EU rule-taker — in the custom union for goods and, possibly in the future, for services under a new Canada-style FTA): in these strange days, this by itself will be a heralded as victory by Brexiters.
