I am extremely glad that the right hon. Gentleman has made that point. I was going to address it in just a moment, because he raised it at the very outset, so I will come back to it shortly.
Let us be realistic. What is the prerogative power here for? It is a bit more like “break glass in case of emergency” than it is the kind of scheme that I think the Liberal Democrats are looking for. I think we can all agree that people do not welcome needless upheaval—Brenda from Bristol put it pretty well—but they do want their role in resolving a crisis. Vernon Bogdanor, in evidence to Committees along the journey of this Bill, made the point very well. Essentially, unsuccessful Governments have attempted to get to five years. Successful Governments have gone to the people at four years. Anything short of that is a national emergency. What we are talking about today is what needs to happen in the cases of emergency or crisis. I note the arguments made for fixed terms, particularly by the hon. Member for Edinburgh West (Christine Jardine), but we have tried designing those and they have not worked, so what we are returning to here is an arrangement that did work.
I want to reassure the House on a couple of points, as I said I would to the right hon. Member for Orkney and Shetland. The long campaign expenditure controls are not changed by this repeal. Those arrangements are that if Parliament is not dissolved 55 months from its first meeting, then the long campaign controls apply. That situation continues. That has not changed. I also point out that there is a measure in the schedule to this Bill that adds to that in respect of third party donations. The schedule also provides that the trigger for the election timetable in the case of a general election is the Dissolution of Parliament. That is an important safeguard that we have built into the Bill, acknowledging arguments made on that note from the Joint Committee.
I conclude by thanking hon. Members once again for their contributions this afternoon. It has been a very good debate, and I am delighted to be back and to be part of it. My priority with this Bill is to encourage consensus, because that is what will give us the most effective operation of the conventions that must endure once again.
I close with the points made by the Public Administration and Constitutional Affairs Committee on the nature of our constitution:
“at the heart of the UK’s constitutional arrangements is a fine but constantly-shifting balance of convention, principle and law, that provides clear guidance, but also flexibility… In areas of prerogative power, the Sovereign remains the constitutional backstop.”
I could not have put it better. None the less, the hon. Member for Strangford (Jim Shannon), in his inimitable style, did put it better. He said that our institutions are often the envy of the world, and I could not agree more. It is those that I want to uphold. This Bill will return our country to successful constitutional arrangements that have stood the test of time and will continue to serve the people, with the choice ultimately in their hands.
