A new EU border on the island and the imposition of controls could seriously impede freedom of movement between the two jurisdictions, for both goods and people.

According to UNITE “the imposition of passport controls at the border with Northern Ireland would be at best inconvenient and at worst a worrying regressive step in terms of facilitating cooperation between both parts of the island… the maintenance of the Common Travel Area cannot be taken for granted.”

This would have serious implications for Irish citizens seeking work in the UK and NI (and vice versa) and might also undermine the right to residency of a large number of UK born nationals in this jurisdiction and vice versa.
