For the person on the sign-up screen, the politics of the under-16 plans are invisible. What they meet is an age check that either takes seconds or sends them away. For the platform behind that screen, the politics matter only up to the point where they settle into a duty, and then the same practical task appears whichever way the argument lands.
The government’s 15 June 2026 announcement that it will legislate to keep under-16s off social media drew reaction from every part of the House. Read together, the responses agree on more than they dispute.
What each party is saying
Labour, as the government, owns the proposal. It sets a minimum age of sixteen for the main platforms, adds limits on features such as livestreaming and contact from unknown adults, and puts enforcement on the companies rather than on children. It is a firmer line than ministers held for much of the past year, when they favoured flexible powers over a hard age limit.
The Conservatives have welcomed the move and claimed a share of the credit. Leader Kemi Badenoch said the government had “finally woken up to the dangers of social media for young people”, and pointed to Conservative-led efforts in the House of Lords earlier in the year. The party’s posture is supportive of restriction, with a charge that the government arrived late.
The Liberal Democrats want action but are not satisfied with this version of it. Leader Sir Ed Davey said families “have been crying out for action”, while calling the policy “half-baked” and questioning whether it will keep children safe in practice. The party’s position is to push for more, not less.
Reform UK has opposed the plan, arguing that determined users will find ways around it and raising what it describes as concerns about where mandatory age checking leads. The party frames the measure as ineffective and as a step towards wider identity requirements.
A fair reading of the spread is that the disagreement is real but narrow. Three of the four parties accept that under-16s should be kept off mainstream social media. The argument is about how far to go and how to enforce it, not about whether children need better protection.
How Parliament got here
The cross-party history is the clearest evidence that this is a shared concern rather than a single-party project. A backbench bill on children’s online safety, introduced in late 2024 with support from both main parties, was narrowed during 2025 but kept the question alive. In January 2026 the House of Lords voted, with cross-party backing, to require platforms to block under-16s within a year. The House of Commons rejected that timetable in favour of more flexible ministerial powers, and routed the question through the national consultation that has now reported.
That consultation drew 116,211 responses, with ninety per cent of parents saying they would support under-16s not being allowed on social media. The June announcement is the government acting on a mandate that built across two Houses and several votes, rather than a position taken in isolation.
Why every party is relying on age verification
Every party in this debate, whatever its view on the age limit, is relying on the same assumption. That a platform can tell, accurately and at scale, who is under sixteen and who is not. Without dependable age checking, a statutory age limit is a line nobody can enforce and a flexible power nobody can exercise.
That is an age-assurance question, and it is the part of the debate that is already further along than the legislation. Under the Online Safety Act, services accessible by children have had to use age assurance Ofcom considers highly effective, with enforcement live and fines already issued. Ofcom has named the methods it regards as capable of meeting that bar, including open banking, mobile network operator checks, photo ID matching, credit card checks and digital identity services.
The parties will keep arguing about the mechanism, as they should. Underneath the argument, the means of doing the check already exists, certified and operating today.
Where OneID sits in this
OneID is certified under the UK Digital Verification Services Trust Framework, the standard that governs how verification providers operate. It supports five of these methods, so a platform can confirm a user’s age in the way that suits its audience, without collecting more personal data than the check requires.
Whichever way the legislation settles, the question Parliament is really asking, whether a platform can reliably tell who is under sixteen, already has a working answer.
