I thank the noble Lord, Lord Purvis, for his clear elucidation of the impact of these amendments. To give a practical example, the dairy industry in Northern Ireland, which I mentioned earlier, is largely all-Ireland in nature, because the greater proportion of the processing of dairy products is in the Republic of Ireland. If grain comes into Northern Ireland through either the red or green lane and could be used by a dairy farmer, the DAERA vet—the department vet—cannot certify whether the milk is produced to EU standards. How can he do so with no certificate? The milk is therefore not going south for processing. That also applies to animal healthcare products. The green and red lanes probably work for retail, but not for food processing. It does not work for primary processers who export.
It is worth noting that in 2021 the Northern Ireland dairy industry represented 31% of UK dairy exports overall. Green and red lanes, or the dual regulatory zones envisaged in this Bill, would cause huge damage to the dairy industry. I know that certain elements of the dairy industry, such as Lakeland Dairies, have had discussions with the noble Lord, Lord Caine, and, prior to that, former Minister of State Burns. I know it would be deeply appreciated if the noble Lord could have further discussions with them, because they know the practical outworkings of that.
Further to that, it is clear that these issues are fundamental to the negotiations, including the technical negotiations, that should be going on between the UK and the EU. We want to see resolutions to these issues. I recall what my noble friend Lord Hain said: where there are problems with the protocol—such as with its implementation—there are solutions. If there is good will on all sides, exactly those negotiations will try to resolve those wrinkles and difficulties.
