Prevention and Suppression of Terrorism

I am grateful to the hon. Gentleman for that intervention because he allows me to make my point again. I see that there is a principle involved, but I do not see the difference in principle in changing 96 hours to 28 days, and from 28 days to 42 days. I do not see the difference in principle in those extensions. That is the point I was making. If he thinks it right to detain people without charge for 28 days, but not for 42, I would like him to meet me afterwards to explain where the principle in that difference lies, because I just do not see it. I believe that we must send a strong message to the international terrorist community that Britain is not opening its borders for business from those terrorists and that we are retaining our maximum vigilance and our maximum defence for all our constituents, particularly those who work in London and face that terrorist threat. I would like two simple assurances from the Minister. If we ever see evidence that the 28-day measure, which we are extending tonight, is being abused, I would like the matter to be brought back before the House so we can deal with it. If and when the terrorist threat abates, I would like us to go back to the situation that endured before we introduced 28 days, or indeed 42. I am sure that he will be able to give me those assurances.
