id

The government says its controversial digital ID scheme will not be applied retrospectively, with UK workers only needing it when they apply for a job after its proposed introduction by 2028.

In his BBC interview, Sir Keir set out what he said would be the advantages of digital ID, which will be available to all UK citizens and legal residents.

The PM also told the BBC digital ID could reduce banking fraud because it would make it harder for criminals to access private accounts using forged or stolen physical documents.

She said there was a "fairly thriving" market in the UK for independent digital ID providers, which she called "a local home grown industry".

"If the government expands its digital ID offering, this it could kill off a growth industry," she said.
