My Lords, briefly, I want to support this amendment. I think I was probably responsible for the previous three occasions that the noble Baroness, Lady McIntosh, referred to, in that very early in this debate I asked the Government to set out for each of the European agencies their intention for future co-operation. I did that because, like the noble Lord, Lord Teverson, as chair of one of the sub-committees I know that every industrial and professional sector wants to know what its future relationship would be, as that is the normal way of doing business: they operate with their European counterparts through those European agencies. I then asked further questions about the environment, food safety and, vitally, transport, which would otherwise close down.
I am very grateful that the Prime Minister has picked out aviation as an area on which we must continue to co-operate, and chemicals—the European Chemicals Agency regulates 20,000-plus day-to-day chemicals. Unless we have very close relationships with all those industrial sectors, and on issues such as security and Europol, Brexit will be a serious blow to the way large parts of our industry, public sector and professions operate day to day. We need to give them certainty. I still think it would have been helpful had the Minister produced a detailed list, because we are gradually working our way round to saying that, on all these issues, co-operation will need to continue.
