I took a lengthy intervention from the hon. Gentleman, so I will make a little progress.
The issue of the so-called missing voters was raised by the hon. Member for Walsall South and in a couple of interventions, including from the hon. Member for Blaenau Gwent (Nick Smith). Matt Singh from Number Cruncher Politics has done a significant piece of work on this, which was also validated by the Library. There would be an issue if the distribution of new voters who are not on the register used for the current boundary review was significantly different across the country. However, analysis shows that the distribution of new voters on the electoral roll is broadly consistent with the distribution of those on the existing registers. In other words, although the absolute number of voters is different, those voters are not significantly differently
distributed across the country, which means that they will not make a material difference to the distribution of constituencies.
It is worth pointing out that we have to carry out a review and draw a line somewhere, and that as soon as we start a review, it will effectively be out of date. The Bill promoted by the hon. Member for Manchester, Gorton refers to the register for the 2017 general election. That is already out of date because there has been another one. If we take his logic, we will never have a boundary review, because every time we start, a new register arrives and is out of date.
