asked the Secretary of State for the Home Department how many people certified under the Mental Deficiency Act are on the registers of voters.

The information asked for is not available.

Resisting the temptation to ask a frivolous supplementary question, may I ask whether, as certification under the Mental Deficiency Act is not a bar to a vote, the Home Secretary does not think that something ought to be done to debar people like that?

As I have informed the House on previous occasions, this is one of the matters that is marked for consideration when fresh legislation is considered.

When the Home Secretary does get this information will he add as a footnote: "A number of Members of His Majesty's Government are included"?
