The Brexit issue continues to fuel speculation about the prospects of Irish unity following a border poll. Here Alan Whysall, Senior Honorary Research Associate at the Constitution Unit, author of the Unit’s paper on the subject published in March, and a member of the working group bringing in colleagues from Belfast and Dublin that will look further at the implications of a poll, warns that there are serious dangers looming here for both parts of Ireland – as well as the British government and the wider UK.
The potential breakup of the UK is now spoken about more often than it has perhaps been since the 1920s, fed by the heated politics of Brexit and by evolutions in opinion revealed in polling in Northern Ireland (and Scotland). Some polling in England suggests a willingness to contemplate this, especially if it is the price of Brexit. The subject is sometimes raised rather matter-of-factly in discussion in Great Britain, on an apparent assumption that quick and clean breaks are possible.
In the case of Ireland, at least, this is not so. There are a number of hard realities meaning that any process of Irish unity is likely to be drawn out, and at all stages capable of tipping over into heightened tensions, instability and conflict. And hence a serious preoccupation for the UK, as well as for Ireland. The situation requires handling with extreme care and sensitivity, and not least from London. But its conduct in the last few weeks has all tended to exacerbate the situation.
This blog sets out some of the realities and pitfalls – and why the latter are at present becoming more likely and more serious.
Northern Ireland has a right to leave the UK on the basis of the majority vote
Northern Ireland differs from other parts of the UK in that there is a principle already established in political agreements and in international law that it should leave the UK and become part of a United Ireland in certain circumstances – if a majority of its inhabitants voting in a poll, and the majority also in the rest of Ireland, is in favour. This is a cornerstone of the Good Friday Agreement, and embodied also the parallel Treaty between the UK and Ireland.
And there is a mechanism to bring the principle to life: the Secretary of State for Northern Ireland, with parliamentary approval, must call a referendum (usually called in Northern Ireland a ‘border poll’) at any time it seems likely that a majority would favour Irish unity.
