Ms Oonagh McPhillips:

It changes from time to time. It is quite a dynamic situation. The Garda - our colleagues in the Garda National Immigration Bureau - work closely with the border management unit and immigration service around that analysis so that they can respond. What happens is that if there is an airport of particular concern and you focus on that, it moves to another airport or another country. It can vary quite a lot. That is the nature of what the Garda is doing at the moment. It is basing its responses on an intelligence-led approach. The Garda would be better able to answer that than I would. I do not have responsibility for that.
