HELEN WHITE (Labour): I can only join my colleagues and, actually, first of all congratulate the House for actually, at this point, all being in consensus on this. I actually just perhaps want to take the time to have just one particular thing that I'd like to talk about, and that is the saliva testing itself. Now, Mr Woodhouse talked earlier about how this had been earlier floated in a time when the science around saliva testing was not very sound. I was thrilled to see that it had improved, because I actually worked on a lot of drug-testing cases in the employment arena, and at that point there was a real difference between the testing that was available with regard to urine testing and the saliva-testing process, and one is much less invasive than the other.
