I know we're not really talking Brexit economic impact but consider this - 70-80% of all trade takes place within supply chains global or regional. If the UK drops out of even some of these (automotive, engineering most likely) it is very hard to see how we get back in.

The government belief, insofar as there appears to be one, is that the global supply chain driven economy is going to be replaced by a handful of global technology players. But it isn't clear why this is a replacement, and successful modern economies tend to be diverse.

Threatening international law makes the UK less attractive for global multinational investors, as do increasing barriers to trade including for example difficulties with data transfer to and from the EU.

We'll still have strengths including niche product manufacturing (Maclaren) and various services but we're overall less attractive. Freeports are irrelevant to this. But where overall is the UK economic vision? Nowhere, and that should worry us.
