Mr. Drew Harris:

In respect of movement across the land border, that is covered by an operation called Operation Sonnet. Last year, there were 37 days of action, which resulted in 235 persons being refused leave to land and, in effect, being returned to Northern Ireland. The abuse of the common travel area - the polarity of that can switch both ways - is still a major problem for us in terms of individuals entering the State illegally. Last year, there were 156 deportations and 1,116 individuals voluntarily returned. That gives some idea of the scale, yet there are individuals who regularly turn up and apply for international protection who have not come through our airports or ports. We can only then surmise they are using the land border to enter the State. That is still the most significant entry point. At this moment, I cannot say what that percentage is. Mr. Kelly might be able to help with regard to the recent work on that.
