I've just found out that people can use an expired UK passport as ID to vote. As long as they still resemble the image in the photo.
I really think this info has been hidden by the government and wanted to urge everyone to check if they can now vote.
My friends and family members thought they would not be able to as they have no current valid photo ID.
Go through this checklist/ form to see if you have the right ID.

Hope the link works?
Let's all vote!
