I wish to return to the issue of the island of Ireland and the Minister's statement that duty free shops would be at airports and ports. In the context of a no-deal scenario, our island would have a European frontier, and on this island there are well-established ferry crossings, for example, Greencastle to Magilligan in Derry, Carlingford to Portaferry and Omeath to Warrenpoint. I am referring to ports that would be deemed to be in different jurisdictions from one another. Could a duty free scenario not arise in respect of those points of crossing?
