UK threatens hard under-16 social media ban after Downing Street ultimatum

The UK Prime Minister summoned senior social media executives to Downing Street in April 2026 and warned of a legislative age ban if platforms fail to improve child safety. The threat follows government acquisition of new enforcement powers under the Online Safety Act. Australia's 2024 ban on under-16s serves as the explicit model. The government's consultation on children's digital wellbeing will determine whether it pursues primary legislation, strengthens existing enforcement, or relies on regulators.
