That's the thing about "no deal". The UK then exits and crashes out of existing deals without replacing them with other deals. The only reason these articles appear in the papers is because some Brexit headbangers like the Redwoods of this world don't understand that "no deal" is exactly that: no deal. Nothing. In their heads however it seems to mean "out of the EU and of course the common sense bit miraculously remains untouched because we never voted to bin that". But that is either magical thinking or it would mean........ a deal (however bad that deal would be).
There is a solution for everything so it is not impossible. However, the question is whether it all can be done before the end of March 2019.
