I wish to speak briefly, as chair of the all-party group on the chemical industries, to new clause 61, tabled by my hon. Friend the Member for Wakefield (Mary Creagh). I am not going to rehearse the arguments that she has already made; she gave an incredibly strong account of why we should stay within REACH. It suffices only to say that the chemicals industry does not want to see any drop in regulatory standards. It wants to stay within REACH, for obvious reasons, not least because it wants a smooth transition post-Brexit, and staying within REACH makes sense in that regard. When an industry as big and as important to our export profile as chemicals is so vociferous in its argument that it wants to stay within REACH, this House and every Member of this House should take notice and think very carefully about how they proceed on that point.
The remaining comments I want to make are on new clause 13. It really saddens me to say this, but I am very sad to see those on my own Front Bench making an argument about new clause 13 that I believe to be erroneous. Their argument tonight has been—on paper, if not on the Floor of the House—that the clause actually ties us into the customs union. Nothing could be further from the truth. My hon. Friend the Member for Nottingham East (Mr Leslie) made it absolutely clear that this clause is about making sure that the option of staying in the customs union is not taken off the table.
I shall not go into all the various arguments that have been made, because we have not got time, but I do want to ask every Member of this House, particularly my colleagues, to bear in mind the importance of not ruling out membership of the customs union. Voting for the new clause tonight will be an act of conscience that will send a powerful signal to the country and the Government that we understand the importance, potentially, of the customs union and the importance of giving the Government the strongest possible negotiating position when it comes to that regulatory alignment that we have heard so much about in recent days.
On Ireland—I will finish on this point—my hon. Friend the Member for Nottingham East made the case about avoiding a hard border between Northern Ireland and southern Ireland, and made the point that that is one of the key reasons why this new clause, and the potential for staying in the customs union, is so important.
