Both sides of the house are in part responsible for not agreeing a deal. Labour's position is simply that the deal the conservatives have put on the table, is a shit deal, and most conservatives agree that it's a shit deal, so it's not really on Labour if the people vote for a far right candidate.
They're still going to get accused of being to blame by the Tories at every opportunity though if as a result of these 11th hour talks an A50 extension happens that necessitates an election in which it happens. Very explosive political mud to be able throw too.
