I referred to the elements of that amendment, which refers to one part of what became known as the Malthouse compromise, in response to an earlier question from one of my hon. Friends. As I said, the Government have already addressed some of those issues. However, my right hon. Friend referred to the amendment tabled by my hon. Friend Sir Graham Brady. That was about alternative arrangements replacing the backstop, and my hon. Friend also indicated other ways in which concern about the backstop could be dealt with. What we have agreed with the European Union, in a legally binding character, is that commitment to ensuring that alternative arrangements are indeed available by the end of December 2020, so that they can do what that amendment required and replace the backstop.
