The UK government has intensified pressure on major technology companies, warning that stronger action is needed to protect children from harmful online content.

Prime Minister Keir Starmer has announced plans that could require technology firms to introduce additional safeguards on smartphones and digital platforms used by young people. The proposals are designed to reduce children's exposure to harmful material and prevent the sharing of explicit content among minors.

The government has reportedly given technology companies a limited timeframe to implement effective safety measures voluntarily. If sufficient progress is not made, ministers could introduce new legislation and financial penalties to enforce compliance.

The move comes amid growing concern from parents, educators and child-safety campaigners about the impact of social media, online exploitation and digital harms affecting young users.

Officials say the initiative forms part of a broader strategy to improve online safety standards and ensure technology platforms take greater responsibility for protecting children in the digital age.

The announcement is expected to fuel debate over the balance between online freedom, privacy and child protection as the UK seeks to strengthen its digital safety framework.
