Over 500,000 people have signed a petition opposing UK Prime Minister Sir Keir Starmer’s plan to introduce mandatory digital ID cards, or “Brit-Cards,” for all adults.

Starmer argues the cards will make it harder to work illegally and improve border security, while critics warn they risk mass surveillance and cyber attacks on personal data.

The digital ID would also integrate driving licences, passports, NHS services, and National Insurance numbers, and aim to curb visa overstayers.

Labour faces pressure to tackle illegal migration, with over 1,100 people arriving on small boats in a single week.

Opponents, including Nigel Farage and Tory leader Kemi Badenoch, dismiss the scheme as a gimmick that will not stop illegal crossings.

Initial cost estimates suggest £400 million to build the system and £10 million annually to run the associated app, the Metro has reported.

Britain remains the only European country without an ID card, after a previous attempt by Tony Blair in 2006 was scrapped.
