Minister, if I can, and the question I do pose to you, is: when do you see it being commercially available, given that a Minister outside of Cabinet but in Government has said that he agreed with your statements when asked by me in select committee that the national herd size didn't need to be reduced? You and I agreed. He then agreed and then flip-flopped on that position. So is it not a case that we have a tax before technology and this is a back-to-front conversation?
