My hon. Friend is making a very strong speech and getting to the nub of this issue. She has explained why we should be concerned about unilateralism. I share her concerns about food and environmental standards. We have also seen this with covid testing in recent days, including in her own constituency—unilateral decisions are being taken at a UK level to reduce testing in Wales, which is having an impact on our constituents. Does she agree that there is absolutely a reason why we are so concerned about the way that the Bill is being put forward?
