My Lords, I am not sure that the noble Lord, Lord Stevenson, did me a great favour by alleging that I had partial paternity of this amendment, but I will leave that to one side. It is a very simple amendment, setting in statute the view that has been expressed twice by this House, by massive majorities, and once in the House of Commons last week: that leaving the European Union on 29 March by default without an agreement should be excluded. That is what this amendment proposes to do. It does not prevent this Act, as it would be, coming into effect in the event of the meaningful process being successfully completed in the other place. Nor does it do so if the other place should, in the extraordinarily unlikely circumstances, actually decide that we should leave without a deal. However, it rules out leaving by default as a condition for the entry into force of the provisions in this Act. No more needs to be said, and I have a feeling that we may wish to debate that rather more decisively on Report.
