REMEMBER if you registered to vote but you don't have a polling card, *YOU CAN STILL VOTE.*
Go along to your polling station and give them your name and address, they will find you on the roll.
I forget mine a lot, I've never had a problem doing it this way.
Also you absolutely do not need a pen, but it does not void your ballot if you opt to use one. Just make your voting intention clear. #UKGeneralElection
