Re: Brexit just gets better?
Quite simply, they don't tear up trading arrangements that have been built up over decades.
Our arrangement is that we can trade goods and services in the EU (and EFTA to a lesser extent) as though we are all part of a single country.
When we leave we will be most like Turkey, which will mean goods should be OK, but the services we rely on selling will be cut out of the market.
Of course if a Thelma & Louise Brexit were to be allowed to happen, we'd suddenly be trading with the EU on the same status of Mauritania (minus their everything but arms spacial status, of course)
