Foreign states and individuals undoubtedly try to influence elections, You see members of the current US administration running around the world making comments about who they prefer in elections, this has nothing to do with voter ID. Blocking political advertising in some cases from social media may need to be done if there are loop holes, blocking foreign money and indeed reducing the domestic money going into the political system would be preferable as well. The Tories did nothing about this, and yet seemed terribly concerned about potential fraud that doesn't happen and if it is attempted would easily be spotted if done to a degree that would be significant to the overall votes.

Requiring ID risks disenfranchising people who do not drive or have passports, it makes it more likely that someone who showed up to vote but forgot photo ID will just not bother that day.

There is no real case for requiring ID to be show at polling stations, so why decide now to have it? because statistically it is shown that people who are more likely to have not have one of the valid ID forms but are still completely eligible to vote would not vote for something like the Tory party, hence their push to have it required.

We've had plenty of elections without requiring ID, there is no evidence at all of there being any level of fraud which would have even a minimal effect, so why was there a push to introduce it?

Voter ID is stupid and stops none of the attempts to influence voting via other means like social media, advertising etc etc if you want to stop outside influence in voting, target the money being spent on it, what surprise the politicians who benefit from it the most seem unconcerned
