The hon. Gentleman raises an important point. As I set out in my answer to this group of questions, we are considering whether a period beyond that minimum should be introduced. I also reassure him that, from my conversations with the head of the United Kingdom Human Trafficking Centre, I know that longer periods are allowed in individual situations. I take his point, however, that that may not be having the effect that he seeks because it is not known about more widely. We will certainly consider that point.
