My Lords, this has again been an excellent debate and let me say at the outset that I note that support for the amendments comes from noble Lords on all sides of the House. I am not trying to imply that this is a partisan issue, but it is one of principle. I hope that the noble Lord, Lord Butler, the noble Baroness, Lady Wheatcroft, and the noble Lords, Lord Newby, Lord Wigley and Lord Foulkes, who have tabled Amendments 226, 227BH and 357, will believe me when I say that I respect their positions. But this debate has been held many times before, and I therefore hope that noble Lords will forgive me if my argument sounds familiar. The referendum question, agreed by Parliament and presented to the people, was whether we wished to leave or remain in the European Union. Parliament attached no conditions or caveats to that vote.
It was clear in the campaign that a leave vote could lead to a range of outcomes and that not all of us advocating leave agreed about the way to do so. People knew this at the time, it was extensively debated and, in the biggest democratic mandate for a course of action ever directed at any UK Government, voters instructed the Government to leave the European Union.
