Business always wants more business, it’s the oxygen that keeps trade alive.
The EU will not crumble, nor will the UK - business will survive on both sides.
Trade deals are not easily made, there is a forest of bureaucracy and politics to navigate, e.g the plan of Liam Fox was to roll over existing EU deals with non EU countries. He said it would be easy in a no deal scenario. The plan was for 40 such deals by yesterday - he has 8 including with the Palestinian Authority and Faroe Islands.
The easiest of these should have been CHF and so it was, they are the largest of the 8.
Problem is that our astute politicians often forget that it’s business that conduct the deals and decisions on buying/selling never take account of politics.
The Swiss deal in a no deal situation is useless, if in Switzerland I buy from UK tariff free under the Liam Fox agreement, then attempt to resell to my largest market - the EU - I will face sales tariffs - country of origin rules.
Perhaps an explanation of why the PM has changed from no deal vs bad deal etc.
The chances of a no deal by default have increased quite substantially.
Edit: Uk will not be able to reapply with GBP as it’s currency so the exit will be permanent when it happens.
