In a recent trial, voters were required to show ID before voting. 819 people were turned away from a few trial polling stations and did not return, losing their votes.
The total number of cases of voter impersonation recorded at the 2018 local elections NATIONALLY was just 8!
the problem the current government claims to be solving simply does not exist. This might seem like a pointless waste of a policy because it is not evidence based but of course this IS evidence based – It is highly likely that mostly non-tory voters were turned away.
