LONDON (AP) — British Prime Minister Keir Starmer is expected to announce a social media ban for young teenagers Monday, designed to protect children from harmful content and excessive screen time.

Britain would join 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. France, Spain, Denmark, Thailand and South Korea are among others studying or developing similar approaches.
