EU Exit Negotiations

Despite trying to cave in on every EU ask so far, the Government have not been able to conclude the preliminary negotiations in 18 months, yet we are to believe that they will conclude the substantive negotiations in 15 months. They have not been able to agree a good deal with the DUP, yet we are to believe that they will get a good deal from the 27 member states. It is obvious that they do not know a good deal from a bad deal and we are heading towards a no-deal scenario, so when will they start planning and present transparent information on the implications?
