My hon. Friend makes a really important point about the quality of evidence and expertise. That was covered in the forensic science regulator’s report, published earlier this year, which talked of:
“Implementation of quality standards is a means to this end, ensuring a systematic approach to scientific validity, competence and quality.”
The report therefore covers the regulator’s approach, and the report produced in the Lords last year touched on such concerns in a more robust way. I think that what we are trying to achieve in this area will reinforce and improve the situation. There is also the perspective that there ought to be better briefing and understanding within the system, so that, in fields where there may be a variable quality or understanding of certainty, that is explained as a trial makes progress.
