Lord Richard Hermer suggested the information held by the system would be limitedDigital IDs will “probably” hold much less personal data than online cookies, the Government’s most senior law officer has said. The Prime Minister announced on Friday that the Government would introduce a new ID system by 2029 that would be mandatory for people working in the UK. Sir Keir said earlier on Sunday that the system would deter migrants from coming to the UK. You must have ID, mandatory digital ID, in order to work, because we have to stop illegal working. Opposition parties have criticised the plans, with the Conservatives describing it as a “gimmick” that would not help cut illegal immigration.
