As the hon. and learned Gentleman was speaking—he recalled having a cold towel placed upon him last week—I wondered, as his peroration ranged across so many different clauses of the Bill, whether he wished the same fate for the whole Committee, although I fully appreciate his point on the complexities of this particular area of our consideration. They are such that, to get to the basis of why he tabled the amendments, it is necessary to look across a range of parts of the Bill.
In essence, this is probably the difference between us—perhaps it is not, but let me present that at least as my hypothesis. We recognise, as the Bill reflects that different levels of authorisation should apply in relation to different investigative techniques. I think the hon. and learned Gentleman is with us that far, but it is important to say why those different levels should apply. The differences plainly reflect the different operational contexts in which the powers are exercised, and that includes the different organisations, how they use the capabilities, and the statutory purposes for which those capabilities are utilised. We are absolutely clear that those differences are necessary, and that the safeguards that apply to different powers are satisfactory, coherent and effective.
