If he will bring forward proposals to lower to 16 years the voting age in elections and referendums.

What the Government's policy is on extending the electoral franchise to 16 and 17-year-olds.

The Government have no current plans to lower the voting age to 16, but we will of course keep the issue under review.

My question was one of definition. In what way is a vote at 16 in a referendum different from a vote at 16 in a General Election? If there is no difference, why did the Liberal Democrats, who support votes at 16, whip and vote against lowering the voting age in the referendum on parliamentary voting reform?

You are right that there are different views in this Government, as there were-

Order. May I say to the Deputy prime minister that I am not claiming to be right?

The hon. Lady is right that there are differences of view in this Government, as there were in the previous Government, about the merits or not of moving to votes at 16. On the issue of whether such a move should apply only to the referendum and not to other votes, the feeling, not unreasonably, was that the matter needs to be looked at in the round. If we are to take a decision in this House, it should be taken on the principle, across all elections and votes, and not just the referendum.

A recent Demos report established that, in the past decade, 16 and 17-year-olds contributed £500 million in tax to the UK Exchequer, that 4,500 of them serve in the British armed forces, and that they are now capable of being company directors. Given that, what possible reason is there for excluding them from voting in referendums or elections?

I happen to be a supporter of votes at 16 but we are open about the fact that there are differences of view in this Government. That is why the matter is not included in our coalition agreement. The previous Labour Government also had no consensus on the matter, and I assume that that is why the hon. Gentleman's party never brought such a proposal forward when it was in government.

Given that in the past three general elections it is likely that less than a third of 18 to 25-year-olds bothered to turn out to vote, and given that more of that age group vote for contestants in "The X Factor" than for candidates in general elections or likely referendums, will the Government turn their face against the ridiculous proposal to reduce the voting age to 16, until such time as slightly older people have shown a greater commitment to British democracy?

Whether people are entitled to vote should not in principle depend on whether they exercise that right. One can accept the principle that people should be entitled to vote at certain ages, without making that entitlement contingent on their exercising it.

Does the Deputy prime minister agree that there is something slightly irrational about those who, in the previous Parliament, thought that we should increase the age at which people are allowed to smoke from 16 to 18, but who now think that 16-year-olds have the right level of responsibility for the voting age to be reduced from 18 to 16?

I certainly agree- [Interruption.]

Order. I want to hear the answers from the Deputy prime minister.

I was not going to turn to the sensitive issue, at least in my household, of smoking. However, I agree with the hon. Gentleman that on this issue, as on so many others, the Labour party seems wholly inconsistent. It was silent- [Interruption.] They were silent on votes at 16 when in government, and now they are arch campaigners for a change that they never delivered when they had the chance to do so. [Interruption.]

Order. Opposition Back Benchers must calm down. I am very worried about you, Mr Gwynne. You just calm down. You have a fit of the giggles, but you will overcome it, do not worry.
