Re: So what businesses are coming *to* the UK following Brexit, in preference to the EU?
You've named two types of growth business there yourself. Britain will be able to offer greatness and sovereignty after Brexit. It's not to cause foreign business to move to the UK, it's to grow small UK businesses long stiffled by foreign competition; lamplighters, chimney sweeps, scrap dealers, rag and bone men etc.
As for services, there will need to be customs officers, border guards, revenue men, rationing staff, security guards for food and medicine, undertakers, social welfare clerks, special constables, immigration and custody officers, citizenship police, prison warders, the list goes on.
