Sinn Féin has warned the British government against blocking an Irish Border poll, joining forces with nationalist leaders from Scotland and Wales to sign a joint pact predicting “Westminster’s time is coming to an end”.
Sinn Féin Signs Tri-Nation Pact in Cardiff
Sinn Féin leader Mary Lou McDonald and deputy leader Michelle O’Neill travelled to Cardiff to sign the co-operation agreement alongside Plaid Cymru’s Rhun ap Iorwerth and Scottish National Party’s (SNP) John Swinney, the first ministers of Wales and Scotland. According to the joint memorandum, each nation maintains the right to determine its own future, backed by momentum behind their movements. The document explicitly calls on the UK government in Westminster to prepare for, plan, and facilitate constitutional change.
Did you know? The last time a border poll was held in 1973, 99% of people voted for Northern Ireland to remain a part of the United Kingdom, while 1% cast a vote for the six counties to join the Republic of Ireland.
Clashing Views on Border Poll Criteria
The push for a referendum comes as political figures spar over the feasibility and rules governing a vote. According to Sinn Féin MP John Finucane, speaking on Newstalk Breakfast, his party acknowledges that the “fairly ambiguous criteria” for triggering a border poll under the Good Friday Agreement has not been met. However, Finucane emphasized that the democratic right to a future referendum cannot simply be dismissed or taken off the table by any British prime minister.
In contrast, DUP MP Gregory Campbell argued against holding a vote, stating that such a debate is divisive and would fracture communities. According to Campbell, there is no prospect of the criteria being met, and political leaders should focus instead on uniting people.
Westminster Opposition and International Reaction
UK Prime Minister Andy Burnham stated during a visit to Belfast that a border poll is “off the table” for now, preferring instead to focus on the things right in front of us in the here and now. Downing Street officials reiterated in Westminster that the Prime Minister believes strongly in the union and wants to focus on the cost of living instead of constitutional debates and referendums. These remarks follow polling in May by the Institute of Irish Studies showing that 50% would vote against a united Ireland if there was a referendum tomorrow, compared to 36% in favor and 14% undecided.
Meanwhile, international figures have also weighed in on the debate. During a visit to the Republic for the Irish Open golf tournament at his Doonbeg course in Co Clare, US President Donald Trump stated that he would “love” to see a united Ireland. According to McDonald, Trump’s intervention showed the US believed reunification was “inevitable”.
