Electoral Administration Bill

Does my hon. Friend agree that using national insurance numbers and data sharing between local authorities would help to overcome not only the problem of people who are entitled to vote not being on the electoral register but of those who live in more than one place voting twice in general elections? The latter is especially applicable to students who are registered in their university town where they live temporarily and in their home town where they have been brought up. There is an opportunity to vote twice in general elections and no easy way of tracking that and ensuring that it does not happen.
