The right hon. Gentleman has made his point, and we will obviously disagree on what I have just said.
Our view, agreed with by most of the Joint Committee on the draft Bill, is that the data required to link an IP address to a device is one such category of data that is required and therefore we welcome what in principle clause 17 seeks to achieve. I say “in principle” because we do have some concerns about the drafting of clause 17, which is why we have tabled amendment 5.
