Reading the news this morning, it's obvious that the DUP and the Tory rebels are going to tank any deal. That will force a general election but instead of that being a cause for celebration, we will get Corbyn who also intends to tank any deal - he's consistently voted against all EU treaties in his career.
The only saving grace would be if the government at the highest level decided to put the brakes on leaving, but the cabinet is stuffed with Brexiters and David Davis is stoking them up to vote down any deal or to resign. Unless the HoL comes up with a genius plan or a plot from House of Cards appears before our eyes and Her Maj steps up, we're screwed.
