Counter-Terrorism and Border Security Bill

Before the noble Lord withdraws his amendment, does he share my concern about the creation of a provision where the boundaries are so woolly and grey? His amendment would have the benefit of being quite clear about proscribed organisations—everyone would know where they were. Essentially we have heard the Minister say that the Executive and the agencies that support them will know things that the rest of us do not know and will stop travel in a situation that they cannot necessarily describe. I am not entirely sure how in that situation Parliament can scrutinise the decision through the procedure to which we have been referred.
