Counter-Terrorism and Security Bill

My Lords, in relation to this group, without I hope stretching anyone’s patience, I will just repeat two questions that I asked at Second Reading, to which I do not think I got an answer. The first question, which may be very daft, is why it is not possible to use powers under Schedule 7 to the Terrorism Act to retain passports for up to seven days. Why can those not be used for outward travel? The Minister may not be able to instantly answer that. Secondly, how do you stop a rolling renewal? I gave the analogy of declaring the whole of Greater London a terrorism exclusion zone. How do you stop that just being renewed on a repetitive basis?
