I am very grateful for that answer. Of course, this is a problem we have seen in Wycombe. I have seen evidence of it, which is why I raise it. On the point about a single national database, the House will remember that we had this conversation in relation to the NHS track and trace app. As a software engineer, may I, through the hon. Member, encourage the Electoral Commission to take the advice of expert software engineers on how such uniqueness could be assured on registrations without having a single national database?
