The supposed “problem” of the post-Brexit border between the UK and Ireland has become a much-debated topic. It is alleged that, unless the UK (or at least Northern Ireland) remains within the EU customs union or, as sometimes claimed, inside the single market, the resulting bureaucracy will lead to massive tailbacks at the UK/Irish border while paperwork is checked, and that this will lead to a breakdown of the better community relations of recent years and even a return to terrorism.

This paper explains why these assumptions are not only unfounded, but grossly exaggerated. It explains the issues involved, sets out some practical measures which have the endorsement of leading authorities in the field and outlines a proposal for how UK/Irish trade could be conducted after Brexit to achieve a frictionless border.
