Overall, there seem to be two solutions available on Brexit. Either the single market, or no deal. May is trying to concoct a kind of half single market, but the EU will not accept this, as it smashes the single market.
On no deal, there are very different predictions, ranging from it making little difference, to blocked borders and ports, shortages of food and medicines, and grounded planes. I would have thought the latter would produce an election, but ironically it might not change much, as Corbyn seems hostile to single market. Another possibility is an emergency settlement.
Some people are getting nervous about shortages of medicines, I think the food thing is still a joke, isn't it?
