I am going to continue. The point about identity is crucial, because we have to understand that the Good Friday agreement's effects were not just economic or governmental, but profoundly psychological. By enshrining these principles, the agreement turned a page. The great danger is that Brexit is seen as going back, and we must not go back in any sense of the term. So if hon. Members want to know why the amendment is important and why it is necessary, I say to them that that is why it is necessary. It is because we must hold dear to these principles in a new political context, where, for the first time in history, one country is going to be outside the European Union and its neighbour is going to be inside it. We have never had that before. When the agreement was signed, it was different: both countries were members of the European Union. Twenty years on, we must guard against any complacency that would see the agreement as a 20-year-old document that can simply be put aside. The agreement was the basis for a new normality, which has not only saved many, many lives-although it certainly has done-but led to a new normality in trade, in relations between the UK and Ireland, and in relationships within Northern Ireland and on both sides of the border. There is peace, but it must not be taken for granted, be treated harshly or be subject to complacency. Great care must be taken. The Minister and Government Members have, essentially, put forward two arguments for not accepting the new clause: first, that it is technically flawed and, secondly, that it is declaratory and does not add anything. Both those things cannot be true. The truth is that if the Minister wanted to avoid a vote tonight, he should have accepted the new clause. That would have shown that he was willing to legislate for what he said at the Dispatch Box. The excuses he has given for not accepting it are out of the standard book of Ministers' excuses for not accepting amendments. He said, “I agree with the sentiment, but it is technically flawed. I will give the hon. Member a meeting.â€ Ministers have been standing at that Dispatch Box saying that kind of thing for decades. The truth is that if he wants to avoid a vote, he has to go much further and guarantee that he will legislate to put in the Bill a commitment to the Good Friday agreement in the new post-Brexit context in which it will have to operate. By doing that, he would be making a statement confirming that we hold dear to the beliefs enshrined in the agreement. I return to the question of identity. Those in Northern Ireland should be able to choose freely to be British or Irish or both. Brexit must not become a divisive wall that separates those identities. It must not mean losing those all-important words “or bothâ€, and all the beneficial consequences that have come from them.
