Investigatory Powers Bill

The difficulty with the hon. Gentleman’s argument is that he assumes that the Prime Minister of the day, regardless of which party he is in, would take such a decision in a vacuum, but it simply could not happen that way. He would have to be satisfied first with proper legal advice that it is in the interests of national security. Secondly, he would have to be satisfied that it is both necessary and proportionate. Passing all those tests requires a lot of advice, and I doubt that any Prime Minister would take the decision lightly. Bringing any Speaker into that decision-making process means that they must be linked to that legal and security advice to satisfy themselves in the same way as the Prime Minister would have to do. I therefore cannot see the difference.
