May I add my voice and that of my party to the expressions of sympathy for all those whose lives were touched by this dreadful incident and condolences to all those who mourn the loss of a loved one? Three months after I was first elected to this House in 2001, we saw the horrific events in New York and Washington on 9/11. That was followed by emergency anti-terror legislation. I struggle to think of a year since in which we have not had anti-terror legislation of some sort, but still the problem continues. I think we can be fairly certain that, if the answer to this problem were to be found in a formulation of the law, we would have found it by now. As the Home Secretary considers the formulation of a new counter-terror and counter-extremism strategy, we need the involvement of people who do not have any skin in the game—who, in the nicest way possible, have not been part of the failure that has taken us to this place. In particular, can that strategy be informed by an honest assessment of what it will do to end the radicalisation of those in prison?
