Do I have to give my details to 'tellers' outside polling stations?published at 18:19 BST
Image source, ADAM VAUGHAN/EPA/ShutterstockSometimes so-called "tellers" stand outside the polling station and ask voters for the number on their polling card.
They are volunteers who work for candidates. They use the information to check who has voted, so they can remind people who have not yet done so.
They are allowed to ask for your polling card number, but you do not have to give it to them.
