I do not oppose Clause 50 stand part, but I ask the Minister to clarify how it is anticipated the clause provides for disclosure of the details of a warrant to the Intelligence and Security Committee. On Tuesday, we had a lively debate about the extent to which Committees of this House can question and protest to the Secretary of State on warrants. My understanding is that if that process is to perform the function that was claimed on Tuesday, it must be done under this provision or not at all because there is an absolute prohibition on the disclosure and that covers the existence or content of a warrant, the details and so on. That stops the Secretary of State or anyone else disclosing to the House, a Committee or anyone else, and goes to the heart of the discussion about accountability.

It was argued that the ISC can hold the Secretary of State to account and it is important that, if this Bill passes into law, we understand how that is intended to take place. It would not come under head 1, head 3 does not apply, and head 4 is for a different purpose. Head 2 may be the answer, but to assist all of us in our further scrutiny of the provisions relating to the role of the Secretary of State and the judicial commissioners, it is important to identify the legal route by which the Secretary of State can be held to account and answer questions within the territory demarcated by clause 49(4). At the moment, it would be an offence for her to disclose any of those matters. Unless there is a route that allows her to do so, that seems to be an absolute bar.
