Among much else, in the event of a no deal there are some 40,000 items that would need to be negotiated individually, across every department, and with all remaining EU members having to agree on each. No way could the current hopeless gov cope, I don't believe it could be done by the most devoted gov, and even if it could be there is no incentive for the EU to cooperate.
Any public no-deal contingencies being worked on by Frau, um, the EU, would be backed by a very private malicious intent toward varying degrees of disruption, delay, inconvenience and economic losses. They, she, will be pressing the buttons.
Meanwhile, the EU are as worried at the prospect of a no-deal as we should be, they never viewed this as a remote possibility, they don't want it, and they would hate it, but unless they realise it is their intransigence that has brought it to the brink, and backtrack using the 'clarification' camouflage to make concessions, then it could become a reality.
My thoughts, fire away.
