The whole reason for the backstop being in the Withdrawal Agreement that sets out the terms of the UK’s divorce from the EU is that the Republic’s border with Northern Ireland would, after Brexit, be the external border of the EU’s single market – and therefore has to be governed by a treaty between the UK and EU, and not one between the UK and the ROI.
An official from an EU capital also questioned whether the Republic could possibly accept „a bilateralisation that would deprive it of the clout of the EU“.
The plan, it is reported, is to “amend” the 1998 Good Friday Agreement in order make a new joint Anglo-Irish commitment that there will be no return to a hard border in Ireland and no infrastructure on that border in any eventuality.
It is argued that this, coupled with some new EU concessions time-limiting the backstop, will be enough get a decent slice of the 118 Tory and 10 DUP on board.
