I thank my right hon. Friend for his comments in relation to what I have been doing. I recognise that that concern has been raised, but there are a number of reasons why I believe that it is met by the arrangements in the withdrawal agreement. It is very clear in the withdrawal agreement that, if the backstop is implemented—and it does not have to be implemented—it is only temporary. It is clear from the point of view of the European Union that the legal base of the withdrawal agreement is article 50, and that that cannot be used to set up a permanent arrangement. Finally, if the backstop is exercised, we have the ability to ensure that it is superseded by the future relationship, and the intent to develop that future relationship in time for the backstop not to be used is clear throughout the document.
