Data Protection Bill [Lords]

Of course there should be national security opt-outs, and when we were changing the rule from 30 to 20 years, I was one of the Ministers who ensured that they were strong. My anxiety is, however, that all too often the security services impose a complete blanket ban, which means that we as a nation are not properly able to understand what happened in the 1930s, 1940s and 1950s. If we were better informed about that, we might be able to make better decisions for our own national security in the future.
