UK Prime Minister Keir Starmer announced on June 15, 2026 that Britain plans to ban social media use for anyone under 16, covering major platforms like TikTok, YouTube, X, Instagram, Facebook, and Snapchat starting in spring 2027. The move aligns the UK with a growing international trend toward stricter online safety rules for children, following similar restrictions in other countries. Enforcement mechanisms and how platforms will verify age remain in development, with Starmer warning that the government will fight back if tech companies resist compliance.
