UK Prime Minister Keir Starmer announced plans to ban children under 16 from social media, following similar bans in Australia and other countries. The government is currently consulting on the policy and preparing legislation, with officials including Technology Secretary Liz Kendall working with the media regulator Ofcom to develop age verification systems by October. This is part of a broader global trend toward stricter regulation of social media access for minors, though implementation details and enforcement mechanisms remain to be determined.
