Identity Cards Bill

Has the hon. Lady, in the course of her diligent analysis, considered the extremely difficult problem of assessing the extent to which the wide-ranging powers in the Bill will be used or not used? There is a great deal of uncertainty about the extent to which certain powers will be used, and indeed about whether the whole process will be extended to involve designated documents. As I said in an earlier intervention, the process seems to be endless. Has the hon. Lady seen any calculation that reveals the impact of the powers if they are used? When an aircraft or a ship is being built, it is possible to see that it will end up as a product. Here, we are talking merely about a vague use of powers.
