Retained EU Law (Revocation and Reform) Bill

I have listened carefully to the Minister’s response. When I spoke earlier, I said that the letter from the noble Lord, Lord Callanan, was very helpful, but I have not had a specific answer, taking my example of fragments of plastic in bottles of water, as to whether the Government would respond to that requirement for change in food and food safety legislation. Would the Government regard it as a technical advance, which the Minister referred to, or as unduly onerous regulation, which she also referred to? What would happen if, for example, the Welsh Government decided they wanted to go to a higher standard of plastic in water bottles but the UK Government decided they did not want them to go to that higher standard? If the Minister cannot answer that now, could she give us a commitment to write with that worked example and give us an indication of what is unduly onerous EU-based legislation and regulation and what is technical advance?
