They've been talking about applying it to postal votes too, I have no idea how that'll work, but it'll disinfranchise myself and my partner, disgusting slimebags that the tories are.
The act of needing to apply for it will disenfranchise people. You won't be able to just pop in and do it on the way back from one of your jobs if you didn't have time to apply in the first place. If you have caring responsibilities and/or multiple jobs it's something that is easily forgotten about due to a lack of time.
Not hugely in favour of ID cards but if we all had them automatically it wouldn't be as much of an issue.
I don't drive, and don't have a (valid*) passport, they've claimed you can apply for an ID (not free), but as a trans woman it's unlikely I can possibly have the documentation required - I believe a birth certificate is required for one; mine does not match my legal name obviously, and all other government documentation (NHS details, National Insurance card, tax documents) are in my legal name.
Besides which, the government knows who I am, and where I live, since I have to be registered on the electoral roll to even be eligable for postal voting in the first place, so what, other than finding a reason to deny me my rights, is the purpose of a voter ID for a postal vote?
* I do, somewhere, have an expired passport that expired in 2016, but I was unable to find it in time to renew it, and my permission slip for getting a passport in my legal name expired years ago, it would also be expensive, given that I have no need to travel abroad, so £90+ on sorting out a passport just for voting would be outrageous.
Your local council has to provide you with an ID. The Tories want to impose a 3 year timeout period on postal votes. This means you would have to replay in advance once every three years. Postal votes will still be a thing. If they get this through then Labour may prioritise this as something to be removed. There is already so much crap to get rid of and only so much time parliamentary available.
Interestingly in Aus this rule couldn't disenfranchise people because voting is compulsory. Seems like a bit of a strange thing to implement when it isn't, it's not like the UK is getting 110% turnout.
