A petition calling on Sir Keir Starmer not to push ahead with plans to introduce digital ID for all British adults has reached 155,000 signatures.
The petition, which is awaiting a response from Sir Keir's Government and might yet be subject to a debate in Westminster Hall, soared by more than 20,000 sign-ups in the past hour.
More than 330 people have signed the petition in Nigel Farage's seat of Clacton, with the Prime Minister facing a local fight from more than 160 residents in his own seat of Holborn & St Pancras.
However, the largest number of signatures so far have come from Labour-held seats.
Hartlepool, which was won by Jonathan Brash in the 2024 General Election, registered more than 500 sign-ups.
Meanwhile, Alyn & Deeside, Bolsover, Easington, Houghton & Sunderland South, Jarrow & Gateshead East all recorded more than 400 signatures.
Sir Keir is expected to unveil his proposal to introduce mandatory digital ID cards during a keynote speech tomorrow, sources have told GB News.
The card, which is reportedly called a "Brit Card", should be able to verify an individual’s right to live and work in the UK.
However, the ID card will need to undergo a consultation and would require legislation to implement.
Sir Keir's Government began looking at proposals for some form of digital ID for adults in Britain as illegal migrants continued to cross the Channel in their droves.
Ministers believe the scheme could prove vital in tackling illegal migrants working in the black economy.
Home Secretary Shabana Mahmood has already voiced her support for digital ID cards.
Speaking earlier this month, Ms Mahmood confirmed she has "always been in favour" of the scheme.
The Home Secretary added: “In fact, I supported the last Labour Government’s introduction of ID cards.
"The first bill I spoke on in Parliament was the ID cards bill, which the then Conservative-Lib Dem coalition scrapped.”
However, civil liberties groups have also put pressure on the Home Office not to reintroduce digital ID cards.
In a letter to the Prime Minister, the group of organisations said: “Mandatory digital ID is highly unlikely to achieve the Government’s objective of tackling unauthorised immigration.
“The proposed schemes fundamentally misunderstand the ‘pull factors’ that drive migration to the UK and would do very little to tackle criminal people-smuggling gangs or employers and landlords who operate ‘off the books’.
“Instead, it would push unauthorised migrants further into the shadows, into more precarious work and unsafe housing.”
Big Brother Watch's interim director, Rebecca Vincent, also warned the scheme would be “uniquely harmful to privacy, equality and civil liberties”.
Polling conducted by More in Common last November found that 53 per cent of Britons support the introduction of digital ID cards, with just 19 per cent against.
More than two-thirds of 2024 Tory voters backed the proposal, with 60 per cent of Labour supporters and 59 per cent of Reform UK backers also supporting digital ID cards.
Ex-Prime Minister Sir Tony Blair has been pushing for the reintroduction of digital ID cards over recent years.
Sir Tony's think tank this week published a report that suggested there is growing public support for a “super-digital identity card” which would allow people to access public services and report problems in their local area.
