At the start of his remarks, my hon. Friend said that we must be careful about repercussive measures. My concern is that the new clause is repercussive and will lead to calls for similar prompts for other kinds of people—new citizens, for example, or those turning 18. My other slight concern is about what kind of information registration officers are likely to receive about those intending to leave, or who have left. Surely if such a provision is to work, the email addresses of many more people would need to be available to registration officers, otherwise we will have no way of knowing that people have left or are intending to leave.
