Pontius Navigator,
Globally integrated but with customs and people movement barriers between us and our largest trading partner, in fact the WORLD's largest trading block. All those foreign companies who base their manufacturing in the UK and export 80% of production, over 50% to the EU, are going to face the issue of having to relocate inside that trading block, and guess what, they are the UK space industry as well.
Brexit, a trading and economic disaster!
