My company is only one example but I know of many others.I don't get these references about trading with the world etc, it's been a fantastic tool of the Brexiteers to message to the general public "we can trade with the world" as if that wasn't happening before.
It's up there with "other economies are growing at a faster rate than the EU" argument. Yeh, they are, my 5 year old is also growing at a faster rate than i am. Doesn't mean you'd want to trade cars with him though does it.
We cannot trade with the world because we are too expensive. We are too expensive (in part) because of EU regulation that is not required in the countries we want to sell to, such as the US and the Middle East.
The EU (for reasons I cannot fathom) also places tariffs and quotas on imports.
