BoysofMelody, no ID, no vote.
See my previous
With regard to ID, in Northern Ireland I refer you to
www.eoni.org.uk/Electoral-Identity-Card/Electoral-Identity-Card-FAQs
The following documents are accepted at polling stations as proof of identity:
A UK, Irish or EEA driving licence (photographic part) (provisional accepted)
A UK, Irish or EU passport (note: EU passports are not accepted at UK Parliamentary elections)
An Electoral Identity Card
A Translink Senior SmartPass
A Translink 60+ SmartPass
A Translink War Disabled SmartPass
A Translink Blind Person’s SmartPass
These documents are listed in legislation and no other forms of identity can be accepted.
The identification document does not need to be current, but the photograph must be of a good enough likeness to allow polling station staff to confirm the identity of the holder.
As you will see if you go to the link, an Electoral ID card is free.
