I think my hon. Friend has missed his calling: his forensic examination of these documents is to be admired. During the course of the debate I will seek an answer to the question that he raises; I do not have it at the moment. In response to an earlier point that he raised, it is not just the police who are the users of forensic services; very often defence will use them.
Having a consistent regulatory environment that is observed by all means that we will get greater consistency in courts, and therefore there will presumably be less time lost—and a saving—in trials that are broken, cracked or have to be delayed because of differences in forensic evidence.
