//I have my voting card, I need no more.//
You don't even need that, OG. All you have to do is to present yourself at the polling station and say "I am Mr. O. Geezer of 28 Acacia Avenue" and, provided nobody has impersonated you before you got there, you will be given a voting paper.
I find it an incredibly weak system. I agree that citizens should not routinely be required to carry papers proving who they are. However, it is obvious that to secure certain services or conduct many transactions, proof of identity must be asked for. In an ideal world that would not be so but we do not live in an ideal world and large numbers of people are "at it" in so many ways.
Voting is no different. The ability to cast a vote is a powerful tool and every reasonable precaution should be taken to prevent the kind of abuse that was witnessed in the Tower Hamlets fiasco in 2014. It seems strange that people think nothing of being required to provide proof of identity when collection their Amazon parcel (value £5) from the Post Office but baulk at the idea when they wish to exercise their franchise.
My area was among those where the pilot schemes took place recently and it was no problem whatsoever. Most people have some form of photo identity. Older people (who are usually cited as the "victims" when such schemes are announced) have bus passes; many younger people have photo travel cards, driving licences or passports. Every effort should be made to prevent voter fraud (and another measure should be the removal of "on demand" postal voting). If Mr Corbyn is correct in that such a scheme discriminates against ethnic minorities (which I believe he is not) that's simply hard luck.
