Everyone should have got theirs by now. Ring the electoral registration department at your local council and check that they DO have you on the register. If you are, you can vote. It's always possible the card just got lost in the post.

Yes you should be worried we have had ours for weeks.
You can still vote, on the day go to the polling station, they should have your details listed. Take ID.
