UK Borders Bill

My Lords, this is the UK Borders Bill, and therefore it does not just relate to Great Britain but to the whole of the United Kingdom. Will there be any immigration officers on the land boundary between the United Kingdom and the Republic of Ireland? If not, will the Republic of Ireland apply the same entry requirements as immigration officers will require when people enter Great Britain? If not, people will enter the Republic of Ireland—as they now do—and move freely across the land border into the United Kingdom. Therefore, the impact of this Bill will be null and void.
