Immigration, Asylum and Nationality Bill

My Lords, there are comments in the recent report by the noble Lord, Lord Carlile, on the operation of the Terrorism Act 2000, about lax security at small ports and airports and poor management of passenger manifests. I will not go through the quotes from the report, as I am sure that the noble Baroness is familiar with them. The report expresses anxiety that manifest information may be inaccurate, inadequate and given a low level of importance by transport operators, and that vital clues to terrorism may therefore be missed. Conversely, good manifest information can save lives. Why the selectivity? What is the purpose of allowing only the collection of information on certain limited flights or routes when, according to the noble Lord, Lord Carlile, we should be collecting all that information if we want to be safe from terrorism?
