My right hon. Friend was not listening; she probably made up her question before she heard the last paragraph. I said that there would be no law changed in this country without the approval of the House of Commons.
Let me come back to the issue of customs union, since it is important. There are several options on customs union. One is shown by Norway, which is in the single market but not in the customs union. One is shown by Switzerland, which is neither in the customs union nor in the single market, but has a customs agreement. A whole series of options exists, and we will come back to the House about that when we are ready.
On my right hon. Friend’s other point, she intimated that because I gave the undertaking to the Opposition spokesman, it was somehow to the Opposition, not the House of Commons. Any undertaking made from this Dispatch Box is to the whole House of Commons, and she should understand that.
A further area in which our aims have been made very clear is justice and home affairs. As I said in the House last week, our aim is to preserve the current relationship as best we can, consistent with our broader aims. That clearly extends to areas such as security and law enforcement. Even after we leave the EU, the UK and the EU will face common threats, from terrorism to organised crime. As such, I believe that there is a clear mutual interest in continued co-operation in these areas. The security of Europe will remain of paramount importance to us, meaning that we will continue to co-operate as we do now with our European partners to help to maintain it.
As for the area that has dominated the debate so far—trade and the European market—the Government have been as clear as is sensible at this stage. We have said that we seek the freest possible trading arrangements, in respect of both tariffs and non-tariff barriers. The Government’s view is that the best deal is most likely to be achieved by a negotiated outcome.
