Allow me to rephrase that for you....
The voting ID requirement was introduced as a political tactic by the present UK government.
Pure and simple.
Don't believe me ? Look at the ID requirements. They are blatantly centered on the age-group that is known to support the Conservative party, i.e. the elderly.
For example:
Oyster photo-card (RFID travel card with your name and photo on it) .... over 60 ? Yes, you may use it as voting ID. 18–59 ? No, you may not use it as voting ID.
