We are always looking to improve them. We agree that security is paramount. If there are areas that the Chief Inspector of Borders and Immigration brings to the attention of the Government, they will certainly consider them.
Amendment 241A in the name of the noble Lord, Lord Teverson, requires the Secretary of State to undertake or commission an annual survey on illegal migrants residing within the United Kingdom. I completely understand his reasoning and agree with it in theory. He asked whether we agree with the list, I think it is a good start but there are problems. We are committed to tackling illegal immigration. The primary aim of this Bill is to introduce measures to make it harder for illegal migrants to live and work in the UK. However, we do not believe that a Home Office survey of illegal immigration in immigration is achievable, nor that it would deliver the information set out in the amendment. Given the clandestine nature of illegal migration we do not see a practical way to sample a representative population of illegal immigrants to meet the aims set out in the amendment.
As the noble Lord said, there have been research exercises in the past to estimate the illegal population, but these, as he said, have been very speculative with very wide margins of error. They have looked only to estimate the overall level of illegal migration and are not surveys of illegal migrants, which is a wholly different exercise. Very few government surveys are mandated in this way. However, I reassure the Committee that the Government are taking action to improve our understanding of the scale of illegal immigration in the UK. From 8 April 2015 the Home Office introduced exit checks to provide more comprehensive information on travel movements across the UK border since that date. These will help us take more effective action against those who remain here illegally. In the longer term the data will also provide valuable information on the immigration routes and visas that are most subject to abuse, enabling the Government to make targeted changes to tackle this.
I am afraid that the noble Lord will be disappointed that I am unable to give the Government’s support for this amendment, but I hope that the thrust of the new legislation provides reassurance that the Government take the issue of illegal immigration seriously and are taking active steps to counter the problem. In light of the points I have made on these matters, I invite the noble Lords not to press their amendments.
