The hon. Gentleman has been here long enough to know that it is not any particular party that chooses the Prime Minister. It is a question of whether the Prime Minister enjoys the confidence of the House of Commons. That is the constitutional position.
I think that we should stick to the present age limit because we should not set a precedent that might be abused by future Governments. We do not want a pick-and-mix franchise. When referendums are held on issues that would normally be decided by Parliament, it makes sense for us to use the parliamentary franchise rules, while also including Members of the other place who currently cannot vote directly because they have the opportunity to elect a representative here. I shall therefore vote against the amendment, although I have some sympathy for—indeed, I strongly support—the idea of 16-year-olds being able to vote. [Interruption.] The heckling from those who want to deny everyone a vote on this matter is laughable. Last week, they walked through the Lobby to vote against the Bill, apart from one Member who seemed to get a bit lost. This week, they are demanding a vote for everyone who could possibly live here.
We keep hearing about residency. What about citizens of the United States of America, one of our oldest allies, who are resident in this country? We know the answer: the system is based on citizenship and on the parliamentary franchise, and it is right for it to continue on that basis. I shall vote against the amendment, but I hope that Front Benchers have been listening to the debate, because the amendment has raised a legitimate point. In the not too distant future, we should have a proper debate about our franchise, so that we can deal with some of the numerous anomalies that we have discussed today. We could then set a franchise for the 21st century, and give Members who are in favour of reducing the age to 16 the chance to vote for such a move.
