Hilary Benn
I hope the hon. Lady will recognise that the common travel area, which is more than a century old, is of great benefit to the citizens of the United Kingdom and the Republic of Ireland. Many people in Northern Ireland live their lives across that border every single day. Anyone who suggests—I know that she is not doing so—that there should be immigration controls on that border is not being realistic, and it would not be the appropriate action to take. As I indicated in answer to an earlier question, we are increasing immigration enforcement activity across the United Kingdom, including in Northern Ireland, as a result of which 1,000 people have been removed in the two years since the election, including 500 who have been returned to the Republic of Ireland.
