Parliamentary Voting System and Constituencies Bill

I am most grateful to the Deputy Prime Minister for giving way and hope not to detach him too long from his speech. Would he be good enough to explain to me, in the light of the announcement earlier today on votes for prisoners, whether under the Bill prisoners who are currently disqualified from voting in parliamentary elections will be unable to vote in the referendum? Do the Government propose to change that to bring it in line with today's announcement?
