Parliamentary Voting System and Constituencies Bill

In my constituency, a not insubstantial number of people are registered for a postal vote only for local elections, and not necessarily because they are EU residents who are unable to vote in a general election. Although they opted to register for a postal vote only for the local elections, they will expect a postal vote both for those elections and for the referendum and will be disappointed when they receive a ballot paper only for the council elections. Does my hon. Friend think there ought to be more publicity to make such people aware that they will not be able to vote by post in the referendum?
