I thank all right hon. and hon. Members for their contributions on a range of issues, which have highlighted the concerns, passion and interest that so many people have shown throughout the consideration of this Bill. The debate we have had over the last hour and 50 minutes has again underlined that interest and focus, and it is important that the House has been able to debate in this way.
I want to start with the issue of immigration detention, which is one of the key elements of the debate. I want to underline at the outset the fact that the Home Office has a policy to safeguard against unnecessary or arbitrary detention. The presumption is in favour of liberty. Cases must be considered on their individual circumstances. Detention must be used sparingly and for the shortest period necessary. That goes to the heart of some of the elements in new clause 13, which was tabled by my hon. Friend the Member for Enfield, Southgate (Mr Burrowes). This is about having a system that is efficient and effective, but that also treats those within it with dignity and respect.
