Prevention and Suppression of Terrorism

We have had a number of commitments from Members over the years on issues to do with this matter—I am thinking of control orders in particular. Members have stood up and made a very similar speech to that which the right hon. Gentleman is making, in which they have said, "I'm putting the Government on notice. Next year, we're not going to do this," but that has not then transpired. Is the right hon. Gentleman making a firm commitment that if this Government—or perhaps another Government—come forward with this proposal again next year, he will vote against it?
