The missing 6% (?plus) of voters now missing from the EDDC electoral roll

What happens if you don’t register
If you meet the conditions for registering to vote (eg you’re 16 or over and you’re British or a national of an EU or Commonwealth country) and you’re asked to register, you have to do so.

If you don’t, your local Electoral Registration Office could fine you £80. They won’t fine you if you have a valid reason for not registering – eg a long stay in hospital, or you have severe learning difficulties.

So why is the Electoral Registration Officer not doing something about this? Could it be that there is a worry that the missing people may not be majority party voters?
