I will give way to my right hon. and learned Friend in a moment.
In addition, it is a question about what this House requests. I am perfectly aware that sometimes I may say that the Government may be acting abusively, so I am the first to understand that there is a capacity for this House to act abusively. However, what is being asked for, and ought to be respected by any self-respecting Government employee, is that if they are asked to look and see whether they have carried out a communication, within the relevant request, that goes to their official work, they ought to be willing to provide it. It should not be a question of coercion; it should be a question of willingness. If we move from that, that will be the destruction of another convention under which this country has been run, and it will be greatly to our detriment.
