Counter-Terrorism Bill (Programme) (No. 2)

I gain the impression that my right hon. Friend is bringing his remarks to a close. I would like to press one final point on him—the question of whether it is appropriate to have a maximum period for a control order. I am not wedded to two years, which was simply the suggestion put forward by the Government's own independent reviewer. We tabled the new clauses to allow Parliament to consider that, but let us remember that some of these people have been subject—without a criminal trial and without being found guilty of anything—to six years of control either in Belmarsh or under control orders. Does my right hon. Friend accept that, apart from in exceptional circumstances, there is a case for specifying a maximum length of time, or not?
