I take very seriously the points that the hon. Gentleman makes, because there are few deeper scholars of our constitution or parliamentary history than him, but I would say two things. First, sometimes there are constitutional experiments or innovations, and it is understandable that they will have partisans who can see benefits from them; but then we can see in real time and in real circumstances whether those constitutional innovations are right and work, or whether it is appropriate for us to go back to the situation that prevailed before, which has actually proven over time, in a variety of circumstances, to be both more robust and more effective.
The second point is that of course there is always a temptation for Governments or any Administration in power to seek to look to the rules and to derive advantage perhaps from changing them, but the critical thing here is that, ultimately, the decision on whether an election has been called and Parliament has been dissolved appropriately rests with the people. We can look at historical examples; for example, in the 1970s Edward Heath decided to go to the country to ask the question, “Who governs?”. He believed that, in choosing the timing of the election, he was doing so to his party’s advantage, but when he asked, “Who governs?”, the country replied, “Well, not you, mate.” On that occasion, it was the case that a miscalculation on the part of the Prime Minister resulted in the electorate deciding that Edward Heath’s Administration should end and that Harold Wilson’s should take over.
