Newborns could be allocated digital IDs in a 'sinister' expansion of the controversial policy.

Ministers have privately raised the prospect of issuing the new technology to children at birth, along with the 'red book' of health records given to new parents.

It would mark a major expansion of the digital ID scheme announced by Sir Keir Starmer in September to tackle illegal immigration by making all job candidates prove they have the right to work in the UK.

The idea has been discussed in secret meetings held recently by Cabinet Office minister Josh Simons, the Daily Mail can reveal.

He has told civil society groups that other countries already issue lifelong digital identities to babies.

Estonia, whose own scheme is seen by Labour figures as a blueprint, creates a unique number for each infant when their birth is registered. Later on, it gives them access to public services.

Mr Simons also suggested that digital ID could be a way for teenagers to sign in to social media, following Australia's ban on under-16s using addictive apps such as TikTok.

Since announcing the scheme, which is due to be introduced by the end of this Parliament in 2028-29, Sir Keir has tried to highlight the ways in which the technology could make everyday tasks easier – such as childcare or applying for a bank account – in the face of a backlash from the public and many of his MPs.

A protest was also staged against the policy outside Labour's party conference in Liverpool 

But the Government has refused to set out exactly what its plans for ID cards involve or how the scheme will be paid for. The Office for Budget Responsibility estimates it will cost £1.8billion.

Shadow Cabinet Office minister Mike Wood said last night: 'Labour said their plan for mandatory digital ID was about tackling illegal immigration.

'But now we hear they are secretly considering forcing it on newborns.

'What do babies have to do with stopping the boats?

'This would be a deeply sinister overreach by Labour – and all without any proper national debate.

'This policy is just another distraction from the Government's total inability to deal with the crisis in the Channel.

'Only the Conservatives have a plan to stop illegal migration – without infringing on the public's rights and freedoms.'

Former Tory Cabinet minister Sir David Davis said: 'This is creeping state surveillance. The idea that we should allocate children ID at birth is frankly an affront to centuries of British history, and is being put out by stupid ministers who really don't understand the technology they are playing with.
