Investigatory Powers Bill

I recall that with the noble Lord, Lord Beith, we went round this course a number of times in the ISC trying to work out where the economic well-being issue could be distinguished from national security. Will my noble and learned friend give a few illustrations now or at a later stage of the Bill to show exactly why this is the case? I think we were persuaded on this. My noble and learned friend said that the current ISC and the current chairman are persuaded. However, will he illustrate why they were persuaded?
