So looks like - as expected - Deal is off the table.
What should happen next:
Johnson and Corbyn put their heads together and make a deal that a) Boris requests a three month extension from the EU, and b) Jeremy agrees to a General Election before the end of the year. BoJo then campaigns in favour of a No Deal Brexit in January, the Lib Dems campaign in favour of revoking Article 50, Labour do whatever they do, and the British people elect a government to make a Brexit decision, this time with a much better (although still incomplete) idea of what it means.
What will happen next:
With this government, and this parliament? God knows. But I bet there'll be lots of shouting.
