Is Brexit propelling Northern Ireland towards Irish Unity?

Guest post by Katy Hayward, Queens University Belfast. This article is part of an ongoing blog series ‘Brexit Countdown’ by the Political Studies Association of Ireland (PSAI) and Political Studies Association (PSA).

One of the unwitting effects of the Good Friday (Belfast) Agreement of 1998 is that it potentially put enormous power in the hands of pollsters in Northern Ireland. If there are sure signs of a majority in favour of Irish unity, the British government is required to bring forward legislation to hold a referendum on the matter.

A key means of assessing changing views in Northern Ireland is through attitudinal surveys, the leading example being the Northern Ireland Life and Times Survey (NILT). Every year, NILT poses the question: What do you think the long-term policy Northern Ireland should be? In the 20 years since the 1998 Agreement, the firm preference of the majority of respondents has been ‘devolved government within the UK’, whilst the proportion of those wanting Irish unity has remained on average around 21% (albeit with wide fluctuations).

There have always been differences between the preferences of Catholic and Protestant respondents on this question, but not in quite such a clear-cut way as typically depicted. Although it is rare for Protestant respondents to want Irish unity, it is not unusual for Catholic respondents to see Northern Ireland’s long-term future as being within the UK. This common ground of accepting devolution is, however, conditional on the terms established by the 1998 Agreement.

It is vital for the union to ensure that devolution works. This is seen in the fact that the highest preference for Irish unity recorded by NILT was 30% (inc. 56% of Catholic respondents) in 2006, after 4 years of direct rule. The trend in polarisation of Catholic/Protestant opinions was only reversed by the restoration of the devolved power-sharing institutions in 2007.

In the present day, Brexit is not only coinciding with the absence of a NI Assembly and Executive, it also diminishes trust between the parties and propels them in different ideological directions. Furthermore, it disrupts the context and functioning of relations across all three strands of the Agreement. British-Irish cooperation will have to adjust to operating outside the common environment of the EU. The significance of the Irish border will change in symbolic and practical ways. And the very issue of Brexit is a fierce point of contention between unionists and nationalists.

Will it also see a change in preferences for Northern Ireland’s long-term future? In 2017 (the latest survey for which data is available), NILT asked the direct question: ‘does Brexit make you more in favour of a united Ireland?’ A clear majority of respondents (64%) said it made no difference. There was, however, a community divide on this; 30% of Catholics reported Brexit making them more favourable towards Irish unity, compared to 18% of those of No Religion, and 5% of Protestants.

Perhaps more illuminating is a comparison between 2015 and 2017 on the question of long-term policy for Northern Ireland, the later results having been gathered after the triggering of Article 50. From this we see a significant rise in the proportion of Catholics thinking that Irish unification is the best long-term policy for NI (from 32 to 41%). For Protestant respondents, there is a more complicated trend: a growth in support for devolution, ‘don’t knows’ and ‘other’, plus a very slight increase in preference for a united Ireland (1 to 3%). Among those claiming ‘No Religion’ there is an increase both in those wanting Irish unity and those wanting direct rule in the UK, which suggests growing discomfort in the ‘middle ground’.

Overall, these results indicate that there is no one clear direction of travel in public opinion in Northern Ireland, but rather that opinion is going in differing directions according to community background. The obvious way to manage such divergence peacefully and constructively would be to bolster the effectiveness of the 1998 Agreement institutions. The multi-level governance of Northern Ireland (including British-Irish and cross-border as well as power-sharing dimensions) is the key to its stability – far more so than any simple binary choice of UK vs. united Ireland.

History shows that the stability of Northern Ireland cannot be secured by the firmness of commitment to the union among a majority of people or elected representatives in Northern Ireland. As such, even if there is little evidence of a changing majority to compel the Secretary of State to call a border poll soon, the British government must adhere to its stated commitment (in the Withdrawal Agreement Protocol) to protect the 1998 Agreement in all its dimensions. In the first instance, this means prioritising the restoration of devolution in the interests of Northern Ireland and the union as a whole.

  1. Who is invited to take part in the NILT? I have lived here all my life and never been asked my opinion, and a quick straw poll says neither have any of my friends! If a biased group is being polled then that will give inaccurate results. I would also suggest that polling in 2019 after over two years of shambolic Brexit behaviour at Westminster will yield very different results.

  2. Please can you outline how people are chosen as part of the NILT polling group, as I would suggest from the opinions above that they may not be representative of the overall pop of NI, given that the results conflict markedly with several, more recent, polls carried out on behalf of the BBC and The Times UK, also outcomes listed by Lucid Polls NI regular opinion tracker. Is this a polling cohort that anyone can sign up to or is it chosen by QUB/NUU? In which case I would very much like to know how. If the UK is basing decisions regarding calling an Irish Border poll on NILT outcomes then I would suggest you are providing an out of date and false basis.

  3. As a life long Republican living in the occupied territory I should say no. The 1998 Good Friday Agreement, forced down our throats by my former Party Fianna Fáil, with full support of Fine Gael et. al brought into Irish politics the reality of the principle of consent, in other words, the reality that we cannot impose upon the unionist minority an imposed re-unification without their agreement or, the overturning of their consent through majority in two referenda in both jurisdictions.
    One poll carried in the Belfast Telegraph in 1998 predicted a Catholic/ Nationalist majority by 2022, the problem with this is the age of majority is, of course, 18 so a majority in favour of re-unification would be most unlikely before 2040, to wit, reunification would be unlikely in my lifetime and certainly not that of iar Uachtarian Sinn Fein so, in light of the landmark judgement R. (Millar et al) v. Secretary of State for Exiting the European Union (2017) the United Kingdom shall, after March 29th 2019, if all goes according to the law, be substantially more a republic than the Republic of Ireland which was only one between 1949-73 whenever it surrendered itself to the, then EEC jurisdiction.
    In light of the above, despite the attempted murder of myself, my Father, his Grandfather by British forces I freely voted to exit the EUmpire in June 2016. Facts, as any lawyer can tell you are all one can rely upon. No less than 86% of Irish law emanates from unelected bureaucrats in Brussels, one may ask why our high taxes pay for politicians? 100% of our laws must, in every respect, conform with the diktat of Brussels, remind me why our forebears fought one empire, and if not our exchequer is subject to fines imposed with little ground for appeal.
    So no, Brexit is not propelling re-unification, rather, and it was my Great Grandfather who made the point regarding his one time enemies the unionists, ‘It’s not the crown they’re interested in it’s the half crown’, so too most people, I fully suspect project fears i and ii to be proven false soon after April and the economy of the U.K. to surge, if I am alive in 2040 and a referendum is called while the Republic is still beholden to toe Berlinucrats I shall vote Nil, pending the rest of my country awakening to the real world.
