As the hon. Member for Harwich and North Essex (Sir Bernard Jenkin) pointed out, one of the most important principles of the United Kingdom is to have a common market and trade between the different parts—that is where the prosperity that attracts people to be part of the United Kingdom comes from. My view, which I have expressed in the House many times, is that the withdrawal agreement undermines the United Kingdom’s economic integrity as well as of course undermining its constitutional integrity, because as a result of the withdrawal agreement part of the United Kingdom will now have its laws made in Brussels and not in London or, indeed, in Belfast. That is why I believe this internal market Bill is so important. First, it ensures that standards within the UK internal market are maintained and that each part of the United Kingdom, for maybe very selfish, very parochial and even very temporary reasons, may want to make differences in its laws, regulations and standards, and, in doing so, damage not only the internal market but their own markets as well.
When it comes to the controversial clauses, I believe that the Lords have done a great disservice to Northern Ireland. I believe, as someone has already pointed out, that they are strong on assertions but very poor on
arguments. The withdrawal agreement, while it promises unfettered access, while it promises that Northern Ireland will remain part of the UK customs territory, while it promises that the integrity of the United Kingdom will be maintained, in reality means that we will finish up with a plethora of trade barriers. We will finish up with laws made that are different from the laws in the rest of the United Kingdom. We will finish up with Northern Ireland being part of the EU single market, rather than the UK internal market.
