Investigatory Powers Bill

I take the noble and learned Lord’s point that “theoretical” is perhaps the wrong word to use and that “speculative” may be more appropriate. I wonder whether he could answer the question I posed earlier. Given that these powers have been available since 2000, can he tell the Committee whether the authorities have ever used them or whether we are talking in abstract terms about something that may have been required in the past? If it has not been used in the past 16 years, it is speculative.
