Interesting from pollster John Curtice.
On the evidence of our key wards, turnout is only slightly down on both 2019 and 2022, while there is no marked evidence that turnout has fallen more in places where fewer people possess a passport.
Meanwhile there is no clear evidence that the swing to Labour is lower in wards where turnout has fallen most. Between them, this evidence does not lend much weight to claims that the introduction of voter ID would depress turnout in a way that would be to Labour's disadvantage.
