If the whole of Northern-Ireland (NI) would be made into a free trade zone. It would:
- boost the Norther-Irish economy
- boost the Irish economy
- The UK can do this (declaring NI a Free trade zone)
A consequence will be that the border around NI has to be made tight. As well the sea border as the land border with Ireland. But not because of the EU but because of Northern-Ireland her new special status.
