I completely agree with my hon. Friend. As I have said repeatedly, this House needs to look at this issue in a much wider context and much more consistently. Members have jumped up and down in this place—I have heard them time and again—talking about greater protections for 16 and 17-year-olds. The problem with extending the franchise to them is how we maintain the idea that they are still somehow a second-class citizen having made them a first-class citizen through allowing them to vote.
The latest protection we have seen is around the rise of e-cigarettes. This House decided in its wisdom that people under 18 could not buy e-cigarettes—they are not allowed to vape. More than that, adults are not allowed to use an e-cigarette or smoke in a car with somebody who is 16 or 17 because it is bad for their health. I just do not see how, logically, we can maintain that position. We can give someone the vote and they may vote for somebody who will campaign and enact legislation that will bring those harmful things to bear on them. That is the fundamental inconsistency.
A number of Members have talked about gradations of development. It is certainly true that different people develop at different times. We all know that the brain develops strongly during adolescence. It starts at the back and moves to the front. Those who are medically minded will know that the science proves that. Our system of capacity has evolved over the years to recognise that we have different capacity at different ages. This whole idea is illogical and makes no sense to me. I welcome the idea that we should decide on a line, but we should level everything up to it, and for me that age is 18. As my hon. Friend the Member for Harwich and North Essex said, 18 is generally accepted across the world and we should have the same.
My hon. Friend is making a very good speech. His tone of reasonableness and balance is a big contrast to what we heard at the start of this debate. If we level everything, that would include the age of consent with all its implications. Is he also saying that we should remove national insurance payments from the under-18s, and that if we keep them those under-18s must have a say?
No. Under-18s should not participate in the taxation system at all. Many are low paid and do not. There is only a very small number who pay tax. In broader social policy terms, because they are among the lower paid, they should not necessarily pay tax as other people do. The current system is very confusing. It indicates that at some stages they are adults, and at others they are not. That might be a reflection of reality: those who have lived with a teenager will know that from time to time they appear mature and then, for no possible explanation, they will be illogical, impulsive or emotional. That is part of the developmental process through they are going through.
