Firstly, the agreement was established in both countries by accepting EU membership. As a result, issues relating to different business practices have simply not been addressed. He described the “genius” of the agreement as a framework for “all relations on our two islands – between the municipalities of Northern Ireland, between the north and south of the island of Ireland and by the Irish Sea.” It could be argued that a hard border would complicate the work of this part of the agreement. 1 Since the publication of the results of the 2016 Brexit referendum and the BRITISH government, which has begun negotiations with the EU to leave the European Union, the issue of the border between Northern Ireland and Great Britain and the Republic of Ireland has proved to be the main point of contention against London and the EU negotiating teams. More than three years after the referendum, and although Theresa May`s government has promised to find solutions to keep the Irish border as transparent and invisible as it was before Brexit, the backstop, contained in the 2018 draft between London and Michel Barnier`s team, is just a trick to push back the Irish border problem. It has not provided a solution because it lacks political support.1 The purpose of this document is to analyze the reasons that may be responsible for such a complex and complex situation. Mark Lindsay (Northern Ireland Police Federation) spoke of his fears of governing a hard border (23 January 17). It will be “the task of the police offering this protection to these agencies [i.e. customs and excise, the border agency]. That puts our officers in the firing line. 9 All this explains why a purely commercial and strictly technical/technological solution to the problem of Irish border and migration controls after Brexit – and British Eurosceptic conservative circles, The European Research Group, supported by experts such as Shanker Singham, It is extremely imaginative in this regard7 – not only is it insufficient, but it is not politically relevant, as it does not address the total complexity and multidimensionality of the soft border system currently in place.8 The UK`s withdrawal from the EU necessarily means transforming the Irish border into a European external border: as such, it necessarily means going back to both the socio-economic and institutional provisions of the GMA.
