I hesitate to intervene again, but I hope these exchanges are proving helpful to the House, as well as to my right hon. and learned Friend and me—and to you, Mr Deputy Speaker. My right hon. and learned Friend touches on an important issue. I think he will acknowledge that it would be undesirable to set an arbitrary figure, but it is certainly the case that the Home Secretary, the Foreign Secretary and the Northern Ireland Secretary would want to take into account the numbers. It seems to me that the numerical case that my right hon. and learned Friend is making is not without merit. I am not sure that this is a matter to be dealt with on the face of the Bill, but it certainly should be dealt with.
