Data Retention and Investigatory Powers Bill

There is debate about whether the powers are new, and I personally do not think they are, but will the Home Secretary give the assurance I tried to get from her yesterday, when perhaps I was not clear enough in asking for it? If she were asked to sign a warrant—these are mostly warranted powers—which involved a power that it was obvious to her would not have been available other than from this Bill, would she refuse to sign it on the basis that a new power had inadvertently been created?
