Parliamentary Voting System and Constituencies Bill

Perhaps the Leader of the House can enlighten me, but I had understood that the fundamental principle of data sharing was that the use to which data would be put would be made explicit.

Have the Government given permission that the data can be used for adding to the list, or is it simply for checking whether people have erroneously registered?
