My Lords, I do not agree with the noble Lord, Lord Kerr, on the matter of alchemy. Nevertheless, I agree with much of what he had to say. These further agreements inject a greater element of urgency into the whole process that is to be carried on and underline that this process will be carried on in good faith. That being so, there remains the outlier risk that a solution will not be found by December 2020. We remain confident that it will be. But in the event that it is not, the backstop will continue for a period. Wherein lies the disaster?
