My right hon. Friend makes a good point, to which I will return in a moment because it impinges on another claim made by the Home Office that is plainly not true.
We have established what these people are not—they are not all foreign national offenders—but we should understand what they are. I do not have time in the six minutes available to me to go through all of them, but I have in front of me case after case of people who have suffered human trafficking, torture, rape, forced prostitution and modern slavery—mostly before they got to these shores, but in some cases after they arrived here too. Many are damaged people to whom the world has dealt a very, very rough hand. And what do we do when they come here for our help? We lock them up for an indefinite period.
