I am grateful to the Minister for his explanation. I did say that the amendments were probing ones and suggested that national security and politically sensitive issues—as with the Lee Rigby case, to which he referred—would have to be outside this provision. The fact is that in 2014 the Home Secretary personally authorised 2,345 interception and property warrants and renewals, which is about 10 a day. Even David Anderson was shocked by the number of warrants that the Home Secretary had to personally sign, which was why he came up with his recommendation. As the noble Lord, Lord Pannick, said, our understanding is that the number of warrants which the Secretary of State will have to sign will increase as a consequence of this legislation. David Blunkett, who has written of his time as Home Secretary, said that:
“My whole world was collapsing around me. I was under the most horrendous pressure. I was barely sleeping, and yet I was being asked to sign government warrants in the middle of the night. My physical and emotional health had cracked”.
I am sure that the current Home Secretary is more resilient than the noble Lord, Lord Blunkett, was in those circumstances.
Another issue, which I spoke about in the previous set of amendments, is the importance of international collaboration, particularly with the United States. I reinforce what my noble friend Lord Strasburger said. In America, federal investigative and law enforcement officers are generally required to obtain judicial authorisation for intercepting wire, oral and electronic communications. A court order must be issued by a judge of a US district court, a US court of appeals or a FISA judge. If we are to have these international co-operation agreements, again, as David Anderson pointed out in his report, it is important as far as possible to harmonise between different countries the authorisation levels of the system of authorisation. I will read what the Minister has said in his response and I agree that the amendments as drafted go too far, but this is something that we can hopefully discuss between now and Report. If not, we may have to bring this matter back on Report. At this stage, I beg leave to withdraw my amendment.
