The claim is that photo ID will reduce voter fraud. But fraud is not a major issue in the UK, and many people cannot afford photo ID.
''Out of 44.4 million votes cast in 2017, there was one conviction resulting from the 28 allegations of in-person voter fraud – that’s 0.000063%. ''
''Here in the UK, 3.5 million citizens do not have access to photo ID and 11 million citizens do not have a passport or driving licence – in 2013/14 1.7 million lack even a bank account. That makes mandatory voter ID – with no free provision – a barrier to many people exercising their right to vote.''
