I honestly can't see a No Deal happening. I dont think there's ever been anything like this happen before? It would be absolutely disastrous for the entire UK populace... Banking, employment, medicine, trade, transport, and so much more.
May has showed her ability to buy herself more time when things got rough, therefore I believe she will probably look to extend article 50 and renegotiate or withdraw article 50 altogether. I honestly can't see any other outcome happening. It's not realistic or feasible.
