Rishi Sunak has defended the controversial voter ID policy as "entirely reasonable" - despite thousands of people in England being turned away from polling stations.
It comes just days after the ex-Cabinet minister Jacob Rees-Mogg appeared to describe the law as an attempt at gerrymandering that backfired to suppress the Tory vote.
May's local elections in which the Tories suffered heavy defeats - losing in excess of 1,000 councillors - was the first time the law applied across England.
