Legislation on the issue will be included in the Queen’s Speech on Tuesday.
The Prime Minister’s official spokesman said: “Showing ID to vote is a reasonable approach to combat the inexcusable potential for voter fraud in our current system and to strengthen the integrity of our elections.
“Showing ID is something people do when they pick up a parcel at the post office or a library book.
“The 2019 voter ID pilots showed that in elections where photo ID was required, 99.6% of electors were able to cast their votes without a problem.”
The Tory 2019 manifesto committed to introducing the requirement to produce identification in order to vote at a polling station.
