Every working adult in Britain will require a Government-issued digital ID card under a 'dystopian' plan set to be announced by Sir Keir Starmer. The idea of a mandatory identification system has long been advocated by Labour as a way to tackle illegal migration. But the proposal is fiercely opposed by civil rights campaigners, who warn it will erode civil liberties and turn the UK into a 'papers please' society. Meanwhile, polls show a majority of the public do not trust ministers to keep their personal data safe from cyber-criminals. Detailed proposals for what has been dubbed a 'Brit Card' could be announced by the Prime Minister as early as tomorrow.Under the scheme, anyone starting a new job or renting a property would be required to show their digital ID on an app so it can be automatically checked against a central database. Currently, employees and renters have the option of showing a number of different forms of physical ID, but there are fears these are too easy to fake. There is also little to stop unscrupulous employers claiming they have made a check when they have not. However, critics have dismissed the plan as a reheated version of Tony Blair's failed ID card scheme, which was axed amid concerns over privacy and soaring costs.Sir Keir's proposals will be subject to a consultation and are expected to require legislation. The UK is one of the few countries in Europe without an ID system.
