My right hon. Friend will be aware that in the course of the court case the Government laid great stress on the irrevocability, in their opinion, of article 50. In those circumstances, I am sure he can understand that the problem facing the House is that in triggering article 50, that irrevocability has to be matched against the excellent words of my right hon. Friend the Prime Minister in setting out a plan that envisages a future relationship with the European Union from outside of it. Will he therefore keep in mind that the debate on article 50 is likely to be greatly facilitated if the ideas expressed by the Prime Minister are put into a White Paper, or similar document, to which reference can be made in the triggering of article 50, without fettering the Government’s discretion in their negotiations thereafter, because ultimately, as he may agree, this comes down to an issue of trust? If the Government can build that trust, they will greatly facilitate their task, and, if I may say so, those such as myself who wish to help them in what they are trying to achieve.
