I am grateful to my hon. Friend for that. Again, it is important to have it on the record in this debate for the House’s consideration that we are dealing with things that could have precedents with wide ramifications that go way beyond the next few days and whether we leave in accordance with the views of the British people or not.
The final of my three points is perhaps even more relevant to this particular proposal: it is tradition that the Government have vested in them Crown prerogative, and the Prime Minister and Ministers act on behalf of the Crown in all international negotiations. That is not just our view, important though that is, in this House of Commons; while we still remain subject to the superior law of Brussels, it is also the law of Brussels. The Brussels authorities—the European Union—do not wish to negotiate with groups of MPs. They wish to negotiate with the UK Government, because it is the UK Government who are the signatory to the treaty and the UK Government who have sought the agreement of the EU to our withdrawal—or indeed to our automatic withdrawal under article 50 should no agreement be reached.
