It all seems like guesswork to me. Currently, there is a wide spectrum of views on no deal, ranging from those who see a blockage of transport routes to Europe, hence ports and airports would be closed, to those who say everything will be OK. I don't know how you pick a position, but then the uncertainty might lead to a deal, or lots of mini-deals, e.g., on aviation, pharma, haulage, etc. What a mad way to run a country though, a bit like playing in a casino. If transport is blocked, how could the govt survive?
