I have been asked to write about the so called cliff edge if we leave the EU without a deal. That is easy to do.
There is no cliff edge.
It’s another of those silly metaphors that have characterised much EU debate for years, like the instruction that we must get on the train, or be part of the convoy. The EU was never either a train or a convoy. It is a set of ever increasingly complex laws and rules, a single currency, common borders, the four freedoms and the rest as they progress to political union.
If we leave without a deal the planes will still fly from Paris to London on 30 March 2019, the Danish pig farmers, and French dairy industry and the German car industry will still send us their products.
