I haven't left the country since I was 18 as I can't afford it. I definitely can't afford £75 for a passport just so that I can exercise my right to vote.
A first provisional driving licence is £43, then £20 plus at least £5 for photos every 10 years to replace it. I have one to prove my age even though I can't afford to learn to drive but many people can't afford that kind of money just to vote.
If we're to provide photo id to vote then it needs to be free or its a kind of voter suppression akin to the ridiculous lines in poorer areas of the US.
I'm all for everyone having compulsory (free) basic id cards but I am against the ones Blair wanted with biometric data etc. A basic card with photo, name, address, dob and maybe medical alerts on would be good. Then there'd be no need to have a licence if you can't afford to drive just to prove your age, wouldn't need a school bus pass to get half price bus fare, can easily prove name/address at the bank etc.
