Numerous social media apps will be banned for under-16s in the UK after Prime Minister Keir Starmer instituted a full ban.

The likes of X, Facebook, YouTube and TikTok are now unavailable to teenagers in the nation, following the lead of Australia, which brought in legislation last year.

Announcing the ban in the past few minutes, Starmer said the UK is taking “world leading action” on social media, and that the legislation would go further than Australia’s. A govenment survey found 90% in favor of a full ban, according to Starmer this morning.

More details are expected in the coming minutes but reports over the weekend said the UK’s ban would include curfews for older teenagers and restrictions on AI chatbots.

During a press conference this morning, Starmer said: “I want this message to be heard loud and clear. I am not prepared to compromise on the safety and happiness of our children, and that is why this ban must happen, and why this ban will happen.”

He told BBC News the regulation will be passed later this year and come into force in early 2027.

The Australian social media ban has been controversial, with American tech giants unsurprisingly reacting with alarm when that one came in. As these giants get closer and closer to Donald Trump in the States, Starmer, who has consistently attempted to keep relations with the U.S. on a solid footing, may find himself falling foul of the U.S. President, although he is at present distracted with Iran.

Starmer’s ban also comes in as his Labour government wavers, with a number challenging him for the leadership.

Deadline has reached out to X, YouTube and Facebook spokespeople for comment on the ban.
