Children under the age of 16 won't be able to access a range of social media platforms in the UK. In an expected announcement, UK Prime Minister Keir Starmer says he will fight back if technology companies resist.

Starmer did not immediately say what apps would be covered. He said it would take effect early next year.

He says he is "not prepared to compromise on the safety and happiness of our children."

With this ban, the UK joins a growing global movement to tighten online safety for children. Australia, Canada, Brazil and Indonesia have introduced legislation or announced age-based restrictions or requirements for children’s access to social media.

Other countries such as Spain, Denmark, and South Korea are still studying or developing similar legislation. France has been debating whether to ban all social media for teens or target specific platforms.
