Like my hon. Friend, I am a passionate Unionist, and I believe in protecting the integrity of our United Kingdom. He has raised issues and I have spoken before in this Chamber about this question of the regulatory differences between Northern Ireland and Great Britain—some exist already—and, in a temporary backstop period, the commitments that could be given by the Government to ensure that there was not regulatory divergence and we did see that regulatory similarity with Great Britain and Northern Ireland. In fact, there are many who consider that the Northern Ireland backstop is an advantage to businesses in Northern Ireland, which is one of the reasons why the EU would not want us to be kept in the backstop. I can assure him that I am passionately in favour of the Union and will do everything I can to protect it.
