What I am asking for is to ensure that we can deal with the concerns expressed by the right hon. Gentleman and other Members of the House about whether the backstop could or would be indefinite. There are two ways to deal with that. The first is to put in place arrangements to ensure that the backstop is not triggered in the first place, and the second is to ensure that if it is triggered, it is only temporary. As I said in my statement, I am seeking further political and legal assurances in relation to those issues, which can be achieved in a number of ways.
