Suppressing the vote of young people?
That would be why those of my grandchildren who are entitled to vote have already got their voter ID. Young people, on the whole, are more used to having to provide identity for things, if what they tell me, is true.
No stable address? I don’t know enough about that one. If you aren’t on the electoral roll somewhere, can you vote anyway, with or without voter ID?
Suppressing the voting rights of older people? If I remember rightly, depending on which statistics you read, older people were blamed for Brexit. Why would the government want to stop older people voting.
Infringement of privacy? Everybody who is on the Internet, even GN, has somebody or someone or something, tracking their every move.
I didn’t vote leave, but at least if we stayed in the EU, we could have blamed the EU for us having to have voter ID as almost all EU countries do, instead of all the other arguments.
