To ask the Secretary of State for the Home Department, what assessment she has made of the extent to which Northern Ireland's land border with another EU member state creates a challenge in protecting Northern Ireland from terrorist threats.

The UK and the Republic of Ireland have long enjoyed a Common Travel Area (CTA) free of routine border controls. However, there are long-established and effective working relationships between the police and intelligence agencies in both the Republic of Ireland and Northern Ireland to mitigate threats. The Government takes protecting our border security very seriously, and there is a high level of collaboration on work with the Republic of Ireland to also strengthen the CTA’s external border.
