I want to return to the topic under debate, which is how this House will scrutinise the Brexit process. To do that, we need to go back to first principles. What is the power and authority of this House? What is the sovereignty of Parliament, and where does it come from? Here, I take a view that will be popular with the SNP. I believe that the sovereignty of Parliament is delegated by the British people. We do not have sovereignty in this House in a vacuum. It is not that God suddenly created the House of Commons and said it would be sovereign over the United Kingdom. Every five years, the British people delegate their sovereignty and rights to us, to implement as we see fit; we then present ourselves for re-election when that period is ended.
Within that, we have had a referendum. It is fascinating to hear from all sides, left, right and centre, that everyone has accepted the result and that the will of the British people must be obeyed, respected and followed—[Interruption.] That is the will of the people of the United Kingdom of Great Britain and Northern Ireland, which, I am glad to say, includes the good people and crofters of Na h-Eileanan an Iar. That needs to be put into practice.
We also know, because this is the legal advice that has gone unchallenged, that the only legal way of leaving the European Union is to exercise article 50. We therefore know that the vote on 23 June was a vote to exercise article 50. All that is under debate is the point at which that is done; the big decision has been taken by the British people.
