A significant majority of people seeking asylum in Ireland over the past few years may have entered the country through Northern Ireland, according to official data that has intensified debate over migration management and border controls on the island of Ireland. The findings have renewed political and public scrutiny of the Common Travel Area (CTA), the long-standing arrangement that allows free movement between Ireland and the United Kingdom.
Figures released by Ireland’s Department of Foreign Affairs indicate that as many as 90% of asylum applicants in Ireland in recent years are believed to have travelled through Northern Ireland after first arriving in the United Kingdom. In 2024 alone, approximately 18,500 people applied for asylum in Ireland, with authorities estimating that most of them had entered the country after travelling from Great Britain to Belfast by air or sea before crossing the open land border into the Republic of Ireland.
The issue has gained increased attention following a recent knife attack in Belfast allegedly carried out by a Sudanese refugee. The suspect, who has been charged with attempted murder, reportedly entered the island through the Republic of Ireland before moving into Northern Ireland and subsequently seeking asylum in the United Kingdom. The case has fuelled wider discussions about immigration controls and the challenges of monitoring movement across the largely invisible border separating Northern Ireland from the Republic.
The Common Travel Area, which predates both countries’ membership of the European Union, allows British and Irish citizens to move freely between the two jurisdictions. The arrangement became even more politically sensitive after Brexit, as policymakers sought to avoid the return of physical border infrastructure that could undermine the peace process established by the 1998 Good Friday Agreement. As a result, the border remains open, with hundreds of crossing points and no routine immigration checks.
Officials on both sides of the border have acknowledged that monitoring migration flows is challenging under the current system. While Irish authorities believe large numbers of asylum seekers are entering Ireland through Northern Ireland, British authorities have also reported concerns about migrants using the route in the opposite direction. The UK Home Office recently said it had identified hundreds of immigration offenders allegedly exploiting the open border during the past year.
In response, Irish and British ministers have begun discussions aimed at strengthening cooperation, increasing information sharing and improving enforcement measures without disrupting the free movement rights enjoyed by British and Irish citizens. Both governments have emphasised the importance of protecting the Common Travel Area while preventing its misuse by irregular migrants.
The debate comes at a time when Ireland is implementing new asylum legislation aligned with the European Union’s Migration and Asylum Pact, which seeks to streamline asylum procedures and strengthen border management across member states. The reforms are expected to introduce faster processing timelines and new screening measures for asylum applicants.
As migration pressures continue across Europe, policymakers face the difficult challenge of balancing humanitarian obligations, border security concerns and the political sensitivities surrounding one of Europe’s most unique and historically significant open borders.
