When I negotiated the Good Friday Agreement nearly 20 years ago, no one foresaw a day when the -United Kingdom would be leaving the European Union. It was impossible to imagine how the issue of the border between Northern Ireland and the Irish Republic, from which the barriers were removed as part of the agreement, would again become an issue of such political importance.
We have the Taoiseach, Leo Varadkar, threatening to veto the Brexit negotiations unless Theresa May gives a formal written guarantee that there will be no hard -border, and we keep hearing the argument that a departure of the UK from the single market and the customs union would put at risk the peace process and Good Friday Agreement. In other words, if the -border gates go back up again we will be back into the Troubles.
